Switch to normal is300h ?
Linas.P replied to Dantebloom's topic in Lexus IS 300h / IS 250 / IS 200t Club
I think what is important to understand is that there are different tyre types - Touring > UHP > UUHP. Generally speaking the grip and steering feedback will become better the higher you go, but comfort is opposite. So touring tyres will be most comfortable (Primacy 4), UUHP tyres (PS4S) will handle the best. Asymmetric 5/6 are UHP tyres, still great compromise between comfort and performance, but they will not be as comfortable as Primacy 4. As mentioned Goodyear has Efficient Performance 2 in Touring category, it handles better than Primacy 4, it is more comfortable than Asymmetric 6 and I guess they are cheaper than Primacy 4 as well. Primacy 4 is good tyre, just kind of expensive for my liking and handling is very dull, grip is not exceptional either, that is why I would go with Goodyear instead, but Michelin likely will have best thread life - all tyres are compromise one way or the other. I personally would get Goodyear Asymmetric 6, but that is because I prefer more sporty handling. -

That was not an option once can have, so must have been upgrade after purchase. ALL Bridgestone tyres are kind of mediocre or overpriced, and none as far as I know are considered good in terms of comfort, I guess closest to competitive tyre they have are new Bridgestone Sport - but they are UHP, so not the type you looking after. And don't get me wrong - Bridgestone is premium brand, they make tyres which are safe to use on the road (unlike most of the budget brands), but at any given price point competitors offers a better tyre for less money. -

Almost forgotten to mention... whatever you get - make sure it is NOT run-flat, because all run-flats have just horrible ride quality. Better get spare wheel and have it in the boot, then have run-flats. -
It is kind of nit-picking, but it is "same level" of diagnostics as dealer, not the same software. I am pretty sure dealers would use something more modern like Denso or Maxxis computers with wifi/bluetooth which are like £3000+, because Techstream interface is kind of dated and slow, but that is decent deal considering it doesn't cost said £3000.

Only those specific 18" F-Sport wheels. Easy £1000 for them. -

Sounds like test drive would have been good idea? In my experience at it's softest setting F-Sport is about the same as "normal" car, but then it has hard and harder modes. That said I believe most of the issue can be fixed with different tyres. The Bridgestone Turanzas which normally comes with this model are generally quite bad tyres, they have okeyish thread life, but sub-par in all other departments especially ride comfort and noise. So replacing the tyres after doing some research to identify quiet and comfortable ones would be one way to go (something like Goodyear Efficient Performance2 or Michelin Primacy 4). You can as well change to 17" wheels and as a bonus people will rip your existing ones from your hands at very high price, because they are kind of in demand... so you may end-up making money when downsizing. -
Beyond simple OBD2 reader Techstream can read the codes from each module directly (those are not seen on OBD2), it can calibrate the modules, reset modules and configure what is available for that car. You can read fuel ratio on simple OBD2 anyway, and so you can do it on Techstream. You obviously can't change it on either. I am not sure if OBD2 has so called "instructed" vs. actual fuel ratio, but Techstream shows both. The VVTI timing maps and fuel ratio maps would be in ECU programming, so those cannot be seen by either of the scanners. ECU decoder/programmer is needed for this - not aware of any off the shelf available for say IS250, but I have seen people soldering pins on ECU terminals and finding the ways to change the ECU programming.

DPF Regeneration
Linas.P replied to Heliwilly's topic in Lexus IS 250 / Lexus IS 250C Club / Lexus IS 220D & IS 200D Club
The difference between normal DPF work and "forced regen" is that later removes restrictions on when DPF regenerates. Normally DPF regenerates at speed above 55MPH (or maybe 60) and in 4th gear or above (basically on open road in country side that you don't drive in the city with black smoke behind you and don't poison everyone around you), when you "force regen" it will start regen as soon as DPF gets to temp even if car is stationary. Removing DPF would make your car illegal to use on public road, with potential of losing MOT on the spot (sadly no risk of that in UK, but in Europe police do checks) and driving car which is not road worthy as well invalidates insurance. That is just few reasons if health of people around you isn't enough of the reason. So let's just say - don't do it! -
What's the problem with electric vehicles
Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
With hydrogen it isn't the cars that are the problem. But in most places like UK for example there are no hydrogen stations. There used to be 3 in London, but the one near me was closed recently. So for example for me the only hydrogen station is like 20 miles away, which in London traffic is 2 hours drive. -

Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
It definitely started like 10 years ago, but I agree since the start of pandemic it really became on the nose ridiculous... perhaps lockdowns and general division added to that, because nowadays you can no longer have varied opinion... you are either in one camp or another. Basically, if you disagree with veganism, or cycling or child gender surgery, then you automatically a bigot and anti-waxer... and it doesn't matter what you think about vaccine or women. Or vice versa, if you don't believe in mandatory experimental vaccine and "freedom pass", then you suddenly ruzzian troll... again it does not matter what your actual opinion is... and generally it seems there are only two options now - either be woke post-modernist liberal or be old fashioned conservative bigot and nothing in between. So some underlying currents were already flowing for at least decade, but this "us and them" divide really kicked in since pandemic... perhaps divisions started since brexshaite, but they certainly became much more pronounced in last 3 years. I think probably contributing factor in it becoming worse is the censorship which was implemented with pandemic... I understand why it was done and some may justify that it may have been needed to some extent to prevent conspiracy theories flowing (remember people burning 5G masts at the beginning?!), but censorship killed much more than conspiracy theories, government really overdone it (and perhaps not by accident). It killed all public debate altogether and this is very dangerous, because free speech is very important. Before opposing opinion could be raised and discussed, even if it ends up in crap throwing contest at each other, having that conversation helped to at least explore opposing views, raise arguments and to find some common ground (sometimes)... but post pandemic that is gone, there is no discussion between two camps, each lives in it's own silo, each reads their own newspapers, their own channels, sits in their own facebook groups and perpetually self-congratulates on how brilliant they are. I think it really reached the point where dialog between two groups is no longer possible, they think so far apart and are so isolated that they neither discuss, nor debate and even if they do they would not be able to even begin to understand alternative perspective. I guess that makes me conspiracy theorist... and ruzzian troll... lol 😄 -
Lexus from Japan are better than those from North America?
Linas.P replied to NemesisUK's topic in Lexus General Discussions
They surely haven't seen Tesla... and by the way I strongly advise for anyone just for educational purposes to go and test drive one, or at least look at the demo car in the showroom. Oh my god they are horrible! Panel gaps consistency, I don't even know what to compare, because every single one is different... body lines... again - no clue what is misaligned because trim doesn't fit by as much as 2 fingers (this is specifically Model 3 rear door chrome piece was like 15mm higher)... paint... I am not talking about orange peel being consistent... there was literally stone and hair stuck under the clear coat. And yes I am crapping on Teshla again, but what I wanted to say is that Lexus build quality is so excellent that anything you say about it is going to be nit-picking, it just can't be other way around because tolerances and QA are so tight... and yes I tend to pick on some models for feeling like Toyota... still even the worst Toyota is million miles ahead of best Teshla. But it isn't even an achievement because Teslas are so bad there is no other established car manufacturer even close to how horrible they are... perhaps BL in 70s would have been close match. Why am I saying this - not only workers attitude is different in Japan, buyers attitude is different in Japan, so small things like rear doors harder to close would never be picked-up in US, because even Canadian/American doing QA would not understand that this is something to check for... As for the person who did the review - I really respect him for having that level of attention to the detail, so that he can tell the car which is 99.8% there vs the car which is 99.9% there. And I kind of like to think I have good attention to the detail, but that is why I could not drive Tesla every... it would just drive me mad. P.S. Am I right to think UK Lexus are Japanese made? -
And that would make sense.. but ATF/Oil isn't really fire hazard... I guess if it leaks then it may be difficult to clean, but if delivery company does it's job right and doesn't kick the box then it shouldn't really leak (assuming it is brand new unopened bottle).

This article might merit a discussion ?
Linas.P replied to royoftherovers's topic in Lexus General Discussions
The problem here is that we don't actually know what the dealer told the customer. Maybe it as response along the lines: "Lexus: sorry the battery is not covered under warranty, we cant help. Customer: yes but it is brand new car... Lexus: yes but it needs to be driven otherwise battery will discharge... Customer: how often I should drive it? Lexus: driving ~20 miles should recharge it... Customer: so are you saying I should be driving 20miles every day (i.e. 7280 year)?!" Obviously I just speculating here, but my point is - it is "AM" who told to the journalist the story, the actual dealer is not named, the actual dealer was not contacted and we do not know the actual advise they gave to the customer. Common sense is that lead-acid batteries will die after a while, I would expect good battery in brand new car to last at least 6 months, but as we know if it got discharged, then it might get damaged and then after that it may only last 3 months next time. And sure AGM batteries are the thing etc. but even then one should be very lucky if battery survives 9 months and suffers no damage after that. So I kind of see Lexus point here - they assume at least basic knowledge from the customer and that car is driven say at least once a month. Now on other we need to recognise that newer Lexus hybrids are kind of crap when it comes to lead-acid battery. Especially something like Lexus CH-R... I mean Toyota UX... ahhh... the tiny crossover thing! It has tiny engine, tiny battery and it just doesn't last if not driven. Other makers like Kia and Hyundai actually uses traction battery to maintain the level of the starter battery and that is smart thing... the Lexus on other hand doesn't have this as an option and it is kind of stupid. The battery doesn't really need that much maintenance... what is consuming it? Just alarm and maybe if you walk by with the keys it triggers smart key module and side lights, with use as such the traction battery is capable of maintaining it for years... So it is kind of weird and kind of backwards that Lexus hasn't thought about it despite having the most experience in hybrid space. -

Seen that one today... cracked me up in the train... what is socially acceptable term now "eggs producing individual"?! 😄 I have no issue listening to the actual experts, the problem is that so called "experts" nowadays more often are the same vegetables who are just pretending to be smart and maybe have degree in gender studies or something laughable like that... but importantly on shows like GMB, they put panel with one actual expert and 3 others who have no qualification at all, but the thing is - they ask and respond to questions in equal way, hosts giving everyone equal time to express themselves and making it look like there is debate between 4 equally qualified people... despite one being actual doctor, other one actual professor in some scientific subject, the third one barista and the last one pink hair lady who hasn't had a job in her life... and she is 37! And we looking at them and expecting a balanced debate where everyone have equal rights to express their "opinion". I am sorry to say, but some people opinion just doesn't matter, because they are not qualified to have an actual opinion... -

Global warming is GLOBAL issue, so it does not matter what EPA says, because EPA is JUST US. This is exactly how vegetables contrive and conflate unrelated issues. There is huge problem with figures from EU and US... why? Because we don't have have industry, we outsourced that to China, India, Mexico etc. etc... and that is why in US and EU transport always has disproportionate % compared to global average. We import the CO2 and don't account it, all out crap is made in China, but we consider that to be China's CO2, but they are not making that crap for themselves, they are making it for us... so if we start correctly attributing the CO2 emitted by the crap we import, suddenly picture changes and transport becomes much smaller part of the issue. The global - that is what matters - global emissions from transportation is fluctuating between years and it is about 10-16%. Passenger cars are 41% of that 10%... but taxis would be passenger cars, police cars will be passenger cars and cars that are not buses and vans are passenger cars, and personal vehicles are subsection of that. What you, me and everyone on this forum are driving are personal vehicles. That is about 24% as far as transportation is concerned. How about not walking next to the road? Do you go to major harbour and complain about ships sailing there? Do you go behind the engine of the plane before boarding and complaining that it blows emissions into your face? Same here - just don't walk next to the busy road, take a walk on the side street (I always do), cycle on the side street or the path further away from the road. Granted it is partially and issue with city planners that they put walks next to the major roads (or none at all)... move them further away from the road and it will be fine. Roads is public infrastructure which helps to move goods and people around, they not meant to be pretty, they don't meant to be nice to walk on the side of... they are meant to bring the chinese crap you ordered on amazon, they meant to be there when you call ambulance or police and they meant for people with cars to get where they going FAST. Besides tailpipe emissions is just part of the pollution, there as well isparticulate matter is from tyres and brakes and road surface wearing down (which us about 25% off all pollution from the cars).. the BEVs being heavier (and all the so popular SUVs - as RX driver you surely part of the problem!) produces much more particle matter (approximately 8% more... that means minimum of 33% of pollution will stay even when tailpipe emissions is 0)... so anyway you cut it there is no avoiding the road pollution, unless you solution is to go back to stone age and just walk everywhere and live "off-grid". -

I travelled across most of the world, if there is one thing I done then travel would be that... been in every single country in Europe, been on all continents and I have never seen SMOG in my life. I only know how it looks from historic footage of like 70's US and then maybe 90's China. But last time there was real smog problem in Europe I was either too young or not even born. I remember when I was a kid they used to spray roads with water in summer, but that was particulate matter issue, not smog. I guess this goes to the same visuals as "child in the pram and smoke being blown from the street in the child's face"... except "it is not smoke, just water vapour on cold foggy morning... and picture is so blurry that one can't even tell if it is coming away from the street or towards the street". Or that picture of pollution raising from the funnels... except they are not funnels, but instead nuclear power station cooling towers... Honestly, I think people nowadays don't know what the smog looks like and with our vegetable vegan pedocylists media they think every time there is fog in the air it must be smog. And by the way as I said - I don't know either as I have never seen smog in my life except of old videos, at least I know what ISN'T a smog. -
I think they are just being over-sensitive... I would just package it well and simply do not declare it is ATF as long as you shipping it domestically. In the end of the day you not shipping something illegal, so I would say it is none of their business to know what is in the package, they getting their money for the weight, their job is to deliver it not to ask questions. That said if it get's damaged or lost I would not expect them to cover it. Now to be fair I have never shipped any oil/ATF, but I have received it many times and there aren't even any stickers to say "oil" inside, so I kind of surprised they mention it is not allowed.

Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
He is full of crap, misinformed and clearly confused between the stats - 41% claimed is flawed "kerbside" emissions test. These are 2 separate measurements - one is global pollution usually converted into CO2 to simplify stats and that is what matters for global warming... and that is clearly only 10-11% for transportation as a whole (road transportation is 5%, so that is probably the measure you mentioning), and private vehicles are only 2.4%, the rest is planes, ships, trucks, public transport etc. So maybe 41% could be private cars within the rest of road transport. There is different measure which has nothing to do with global warming is local/city air quality measures... for that they use so called "kerbside" methodology, which is extremely flawed, easily manipulated. Here is how test is set-up - they put measurement device 1m away from road at 1m height. Now this is all good so far. Seems like quite reasonable set-up representing the emissions from perspective of maybe pedestrian walking on the side of the road, they often like to take example of child being pushed in the pram, because that will be exactly the air they breathing in. This is why I am always amazed that people are so stupid and they do their runs on the side of the road... and cycle on the road... and have their cars set to fresh air (instead of recirculation) when driving in the city. Where this methodology falls apart is that measurements are only correct for that spot, it is not a measurement for overall air quality in the city. Stick the probe next to the exhaust for the gas boiler and you measurement will say that 90% of pollution in the city is from private homes, heating etc. It seems what the agencies conducting these tests are doing is trying to get most flawed results possible. For example I looked at the extensive test in Germany and what they did... they put the probe 20 metres before the traffic lights in busy intersection... they even say in the video "this is pollution hotspot"... Yes absolutely it is because all the cars come to the stop and idle before the intersection, if they for example put the same probe 20 metres after intersection, then measurements would be totally different, or if they put it next to free flowing motorway it would be way lower. Or if they fitted the probe say 25 metres away from the road in somebodies garden, the results will show a lot more pollution from household itself and a lot less from the cars. Besides they don't even know how much exactly private cars are contributing compared to the busses or HGVs, what they do they simply count the number of vehicles passing and attribute it to the number, but that is clearly flawed because bus emits more than a car and loaded HGV more than a bus... and sure in some other tests they specify the weighting e.g HGV is 4x, Bus is 3x, Car is 1x... but that is still way oversimplified and easily manipulated. And this is where they get the ridiculous numbers which The Guardian likes to put on the front page "70% of emissions in London comes from road traffic and 41% of that is from private cars!!!!". So two completely separate measurements which should be used for completely different purposes. The global emissions are important for global warming and this is where BEVs are basically useless and cars are minor issue - basically 2.4% of pollution, which BEVs reduces by about 30%, net improvement of 0.8% in best of circumstances. The second one ("kerbside emissions") which is in theory tool for city planning, logic says - don't put playground next to major intersection... I could figure that out without any measurements, but there is method to madness I guess. In theory it is nothing wrong with the test. For example improved intersection layout could be tested and justified by saying that when you put roundabout or flyover the pollution dropped by 50% in local area. However, this test is susceptible to manipulation and misunderstanding and in last decade was consistently used in anti-car propaganda as the way to "scientifically" claim cars are the issue and fool people who don't know better. Obviously BEVs looks like silver bullet if we just consider this test because they have no tailpipe emissions, but that is because people don't understand the set-up of the test and what it measures. That is like that saying goes - "when the only tool you have is hammer, then all the issues looks like nails"... and that is exactly the case here - if ones is using single flawed test which only measures tailpipe emissions, then the only solution is to eliminate tailpipe emissions. Yes I have been in US, I live in London and I have been in China and I have never seen smog in my life... this thing does not exist since 80s. The dirtiest cities I have been in was Rio and Sao Paulo, Cairo is quite bad as well, and even there I have not seen any smog. Sure there are cloudy days in London, there are foggy days in London, but "smog" induced by sulphur and lead mixed-up with humidity didn't exist at least since leaded fuel was removed from sale. Sure near the major roads it stinks, but I would say major contributor are HGVs which are pumping visible smoke and which are diesel, not private cars and certainly not petrol. Likewise - please share your sources, I am interested! -

Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
It has risen steadily since 90s, so you can count as disagreement... even if it is splitting hairs... I mean we already agree you have arbitrary time measurement for that... so not sure what else is there to discuss. That's is true... the problem is that majority of people can't charge at home and there is nothing that government does to change this situation, the 2030 dates is quickly approaching and we still have massive housing project popping-up not only without charging, but even without parking. And obviously nothing is done to retrofit the existing homes with chargers either. It is not like I disagreeing here - just pointing out the obvious. And the charging is still an issue if you ever go above the range of BEVs, which isn't really that hard to do. Again you talking theory here... "So long as they keep the cells charging at the correct level" basically means charging at 7-22Kw... anything faster than that and it requires cooling and all the fancy "battery management" which was already discussed. You can repeat the same sentence another 100 times, but it won't make you more correct (or rather more wrong). I have no issue with your theories, it is just a fact that it does not happen in practice. Simply said in practice batteries can charge at much lower rate than you would like to think, yes they are managed at the cell level and that is why all the overprovisioning. Basically, no battery can fast charge at the cell level at the moment (depending where we put arbitrary "fast charging" line, according to government even 7Kw is "fast") and any charging at 100, 150, 250Kw are achieved by managing battery pack at cell level. And indeed all advertised charge levels are just up-to (you said that as well basically) and they do hurt batteries. Yes they are designed in such way that even if you always charge them at fast charger, they most likely going to meet or exceed their warranted capacity. But that is not because they don't degrade, but because there is built in spare cells to manage this and still have enough warranted capacity. I don't know if you don't understand it, don't want to understand it or don't want to admit it... The reason there is no perceptible degradation at first is because 75Kwh battery isn't 75Kwh battery, it is most likely starting as 90Kwh or 100Kwh battery and all degradation is absorbed/hidden. You kind of said that in your last sentence, but you still maintain that you right... point is - when computer limits the charging speed is because charging at any faster rate would cause damage beyond the the level of degradation allowed. I think it is you who splitting hair now. Dendrites are what and where they attach to? Still lithium structure, still material transfer between anode and cathode. I am sure you can explain chemistry of all this in more complex way, but that just doesn't matter. End result is same... overtime battery loses capacity and degrades. You calling me out where you disagree with me, whenever I am wrong it remains to be seen. -

Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
I generally with you on this... I am not against BEVs... I am just against the current "type" of BEVs . And I think the "range-anxiety" is misplaced... really it isn't the problem with range, it is problem with charging. Imagine if you would have to pay £500 to refill at petrol station and had to wait 3 hours vs. £5 to do it at home overnight... you would look at the range of your petrol car as well and would always try to have as much range as possible when leaving your home! So it isn't range, it is the cost and the time it takes to charge that is a problem! And sure... Elun the liar Mushk and all the EVangelists keeps saying how it is not an issue - "yeah sure maaaan... but how often you stop at services and you sit down for 40 minutes to have coffee there... and then on occasion as well decide to watch the movie as well... and then as well have massive sticky dump as well which takes you 40 minutes to clean-up after... and then how often you as well just say ffff-it I am just going to stay at stinky Holiday-In for the night... so yeah maaaaan that isn't an issue if it takes 2 hours to charge, because you staying overnight in the motorway services anyway...". NOPE - sorry not for me! Sure on occasion I have to spend 10 minutes looking at some idiot at the till who can't decide what sauce he wants on his hot-dog and maybe overall stop takes much longer than I expected... so instead of taking 2 minutes it takes maybe 15. But I am not waiting more than 15 minutes to refuel... I am not into this "new way of thinking" where I have to alter my perception to convince myself it is ok to spend 2 hours every 200 miles in the motorway services. This "new way of thinking" is basically a brain-rot... it is not just changing "perspective", it is literally dumb and retarded. And ok... I am driving more than 30 miles only once a week, and more than 200 miles only once a month... but when I am driving I want every thing to be ON... and I am not sticking to 60... 70... 80... If I am in Europe I go as fast as it actually goes, because I generally want to get where I am going as fast as possible. Because on 1500 miles trip the last thing I am interested in is my range! (small side note - BEVs not only **** at charging, they as well crap at any speed above 60MPH). So in the end of the day the biggest problem in my mind is charging and that is literally endless pit of problems... capacity, generation, transmission, how long it takes, battery degradation etc. Like there is a lot of problems with that... and until they are resolved I can't see myself in BEV. The global emissions from private vehicles are 2.4% - 2.1 diesel and 0.3% petrol and hybrid combined. So not quite "less than 1%", but the point remains the same - how comes 2.4% are such a big focus, when remaining 97.6% requires no attention. Just doesn't make sense... unless like you say this is a trick to make us all into slaves, who have no freedom and no control... and who can only go where public transport takes them, when it works and only on routes where it goes. -

Linas.P replied to Mr Vlad's topic in Lexus Owners Club Lounge
This was the statement you made... So is it arbitrary or is it not?! I have picked-up two random buzzwords from last few years where it was on every EVangelist dream-list as the tech "which will change the world as we know it tomorrow". Yet nothing come out of it and I have no reason to believe anything going to change that soon. As I said - the discussion is about what exists now and when we have something else tomorrow, then we can make different concussions. For example if there is electric car tomorrow which can do 200miles per charge in most adverse conditions (meaning high altitude, winter, -20C, heating on full blast, everything that could be ON is ON) and most importantly can charge within 5 minutes without degradation of the battery, then I am sold - count me in, I can get rid of my petrol car tomorrow. I don't even need long range, even 150miles will do as long as I can stop and refuel it within the time it takes to ***** and go another 150 miles, because I always said it is not the range that is an issue, most off current BEVs have plenty of range already. But I am not going to count something that doesn't exist yet. That the battery has Lithium in it, that does not mean it is the same battery tech, there is like dozen different types. Then there is battery architecture, other battery aspects like whenever it is passively, actively, water or air cooler. Sure - it seems for the time being water-cooled NCM are the primary type, but it is far from only type... and they all have different properties. Yes the main reason for battery degradation is crystallisation (we can call it "dendrites" if you prefer, crystals are more Lead-Acid terminology, but principal is the same - material transfer between anode and cathode), they grow with every cycle... But this is where we disagree... as you talking purely theoretically and I am talking about what is happening now in practice of BEV ownership/charging. That is where I said - depending on the technology, quality, design etc. they may degrade faster or slower and further it depends on how empty the battery is discharged, how full it is charged, how fast it is discharged and charged, the voltage and amperage of charging, the temperature and a lot more things. Generally speaking charging is what causes this and the faster is the charging the faster battery will crystallise. In theory you right, if battery is overall designed for say 1000 cycles at 100Kw charge, then it should survive 1000 cycles, regardless if it was charged at "1KW, 20KW or 100KW"... However, I simply don't agree that all current batteries are designed for say 100Kw charge, most of batteries in current BEVs are cycle-rated at 7-22Kw, meaning that they will degrade quicker when charging at 100Kw (not saying that all BEVs going to even allow 100Kw). Anyway - point is (and I agree with you here) charging slower than rating won't slowdown battery degradation, but charging faster than rating will increase degradation. Most current fast chargers are above the battery rating for common BEVs, and most current BEVs will allow charging above their rating (obviously not full 350Kw, but many for example allows 55Kw), so in practice it means that "fast charging degrades the batteries" and owner of average BEV basically have to compromise... either choose faster charger to get advertised 40% charged in 30min, but degrade battery faster, or they wait 2 hours and preserve the battery life. Basically you came-up with your strawman interpretation of what you thought I said and then proven the strawman wrong... well done! Calling others uneducated for not being hyped about tech which doesn't exist is not "slightly" optimistic... I would describe it more fanatical... maybe. -

Repair manual usually has them. Some part sellers as well use them on their sites. If it has part numbers I assume it is from parts seller, I assume they have parts journals from manufacturer e.g. https://partsouq.com/en/catalog/genuine/vehicle?c=LEXUS00&ssd=%24*KwEdKThQQEUYX39fcUhFKUVRcXZoGRYbGggODUtuUgpMTQsRVlpWGxwYGh8MBQtUERANFAkKf297ajtaSA8MREsNFAkJMSshHR4EaWp6ZWNUVEQNWEoKFQ4LGERKMw0CCQpJR00JTFhVUgAAAAB-rd-6%24&vid=0&q= Yes - battery mounting is overengineered and at the same time kind of silly on IS mk2... I always thought there must be better way! -

That is true - Lexus itself is an option. I remember needing headlight washer jet cover. Lexus supplies them painted in the right colour for £18+VAT, whereas breakers wanted £60 and you get the colour you get and need to find somebody would will paint it for you. -

It is most likely where it is, Lexus battery clamp design in these models is really finicky and kind of requires 4 hands just to do a simple clamp. That said the old one most likely have it's bottom rotten away or mangled. That is what you need: https://www.ebay.co.uk/itm/394119576960 https://www.ebay.co.uk/itm/225370515158 If you want one from UK, then ask the breakers, but be prepared to pay arm and leg, because they won't go looking for it in the yard for anything less than £50. That is sort of standard fee for any part regardless of the size or value.
