Well despite changing the air intake temperature sensor 2, and the car feeling and driving much better. It has decided to go into limp mode again And as usual, stop the car, turn it back on and it's just like nothing happened. There appears to be a fault with my mini VCI cable so I can't plug it back into the OBDII port until a new one arrives next week. And so the saga continues.....

Hi normski2, Thinking I should have brought petrol version! But I have to say the car just keeps feeling better and better. I would suggest to anyone that has the same problem of a flat spot in power at 2500rpm to change that sensor. And if you can get one second hand one like me for around £10, it's worth a go for that money. I use Millers Diesel Power Ecomax as my usual fill up additive. Works great for me.

Hello everyone,

Well I tried Lexus and Toyota for the sensor but both wanted around £112 inc vat for it. So I managed to find one at a breakers yard that was local to me for only £10! awesome. It came from a Toyota Corolla Verso D4D and the part number is 89424-60010. I imagine any thing that uses the same engine has the same sensors? Any way, I cleaned it up with some alcohol based contact cleaner that does not leave a residue and popped it in on Tuesday (4 days ago) And I have not had a single problem since. I do think the ECU must be getting used to the new sensor readings as the car is feeling a little better each day. But the main thing is no more going into limp mode, well so far any way. And I have driven in conditions that would normally make the fault happen, early morning with cooler air and also raining as well. But all good. Also the problem I had with the car having massive flat spot in power at around 2500rpm seem to be getting better and better the more I drive it. Yesterday I did an 80 mile round trip and really give it some beans on the A and B roads there, and on the way back I put some stuff in with the diesel called "Drive Clean"

(http://www.clean-drive.co.uk) Quite an interesting read. (Available at Motaman if your in Bristol) And on the way back I kept it between 2500 and 3000rpm all the way and again hard acceleration where ever possible. And the flat spots in power are getting less and less noticeable. I will keep you updated as time goes by, well due to the lack of feedback here I don't really know who I'm keeping updated. But if anything I have been talking about helps anyone then I guess it's worth keeping on posting here.

I found it

Any one know where "intake air temperature sensor 2" is located?

Hellooo,

Well I have managed to get some fault codes...

P0093 Fuel System Leak detected - Large Leak (although I can't imagine its true, I cant smell diesel and no Diesel on the floor under car)

P0098 Intake Air Temperature Sensor 2 Circuit High

Any ideas ?

Hi Dave_Wigley,

Thanks for your reply. Well I am getting an "2015 TECHSTREAM TIS TOYOTA LEXUS SCION DIAGNOSTIC MINI OEM VCI Interface scanner" So I will find out what codes are are causing my problems. Well thats if I can figure out how to use it! Although I am quite capable of taking it off, I don't like the look of the job. As the engine was rebuilt just short of 100k miles and now has around 145k I hope it will be ok. I understand they replace the cooler at the same time? Well lets wait and see what the scanner thing tells me. Should arrive this week fingers crossed.

Looks like pics worked! Well I can see them, lol

Hello all,

I had started this in my original post but I think people must be missing it so I thought I would start a new topic about this particular issue.

I was wondering if anyone has any recommendations about cleaning the EGR No.2 on the opposite side of the engine, behind the turbo. Or even if it's worth doing at all. I don't know if it blocks up like the other one does. My engine has almost 140k miles though. Although it had a new engine at 93k miles. The other EGR No.2 appears to be attached the the EGR cooler. But I think it will be possible to detach the EGR and leave the cooler in place. Try these photobucket links for pics, I hope it works...

This one shows the tube and the nuts/bolts that I think need to be removed before I could just take the EGR off...

I can't seem to attach a picture here so I hope the links work. I got
the links by right clicking the pics and clicking "copy link location"
Fingers crossed.

Cheers all.

Well I got a reply. The eBay seller confirms it has firmware virsion 1.4.7 which is good. And confirms it will work and be fully functioning. So I just brought it. Fingers crossed and I will update in due course.

Hi KC14,

Thanks for your reply. Well I am not sure the turbo could cause the sudden loss of power or the imidiate gain of power. We all suffer the turbo lag, although that is more of a problem of the time it takes to spin fast enough. I am just not sure the turbo could loose or gain power so quickly. And also in such a consistant rhythm. I would have thought it would fail, or work. Unless something is making it cut in and out. I also don't really use any oil, 1ltr in 10000 miles. And also, it doesnt chuck out any smoke under hard acceleration. I have no idea, lol. But I am considering getting...

" 2015 TECHSTREAM TIS TOYOTA LEXUS SCION DIAGNOSTIC MINI OEM VCI Interface scanner "

eBay item 271922634101. This seems to be the only one quoting 64 bit compatilibility. Others also say "K-Line" compatible but after contacting they don't think it is. I have read alot about these things and it seems a bit hit or miss as to wheather it will work or not. I have contacted seller for more info. If you google "MVCI 1.4.1" you come accross all sorts of problems from not woking at all to 64bit OS compatibilty issues etc etc. So I want to be sure before I buy. Any way, thanks again and I keep you all updated.

Is any one seeing my posts?

Helloooo

Also just checked Differential Pressure Sensor hoses. I blew through each hose whilst still connected to the metal pipes and I could blow quite freely. I can't find any where on here about cleaning the actual Pressure Sensor though. Can you just squirt cleaner into each hole? Oh canyou actually take it apart to clean? Really hoping some one responds to my various posts.

Thanks

Hi,

Just took breather pipe off rocker and also pipe from airbox to turbo inlet. All clear but did notice oil in turbo inlet. Is this normal?

Hi All,

Quick update, Yesterday weather ok, today raining. Got about 500 yards from my house, came to a stop at a T junction and dash lights up and loss of power. Turn engine off, back on again and back to full power and I expect as usual the dash will reset itself by tomorrow. Also still suffering from power loss at 2500rpm under hard acceleration. If you keep your foot down it also happens at 3000, 3500, 4000rpm etc. like its kangarooing. Loss of power accelerate, loss of power accelerate and so on. Like a switch on and off. It’s not a misfire or like an injectors not working, it's just like ignition is turned off and back on. Doesn’t seem to happen in first gear and I haven't been anywhere I can go fast enough to see if it happens in 3rd or 4th gear etc. Maybe because in 2nd gear the load on the engine is higher? I don't know. Also proves cleaning the MAF did not cure the problem, but it was worth doing as I can feel a difference in the car. Again I will keep updating. And does anyone know of a way of getting the fault codes without getting it plugged in at Lexus? Aslo I was wondering if any one has any thoughts on my previous message about the other EGR. I must also apologise for not responding to earlier thread. I now have alot more time on my hands.

Many thanks.

Hello all,

My how the time goes by! Well I have been having ongoing problems for months now. The car's dash lights up and the car looses almost all power. So I pull over and turn the engine off. When I start it again it has normal power again and the dash resets it's self after a day or two. And this happens sometimes every day or it could be a couple of weeks apart. It seems to mainly do it within half a mile of starting a journey and almost always only early in the morning. Maybe something to do with slightly cooler/damper air? I don't know. Any way I cleaned the EGR again a couple of months ago, around 7500 miles after the first time I did it. But that didn't stop the problem. Yesterday I cleaned the MAF sensor, it was as black as the ace of spades. And I must say the car keeps feeling better and better the more I drive it. Power seems smoother and more of it. Pulling better up hill as well. Time will tell if it has cured the problem I have mentioned. Well all this week I will be driving at around 6.45am so lets see what happens.

On another note I was wondering if anyone has any reccomendations about cleaning the EGR No.2 on the opposite side of the engine, behind the turbo. It appears to be attached the the EGR cooler. But I think it will be possible to detach the EGR and leave the cooler in place. Try these photobucket links for pics, I hope it works...

Havn't had chance to take it on a run yet, but around 20 miles around town and all ok at the moment.

Didn't think about the Battery resetting the fault code. But having said that I don't have anything to read the code. I did think about the water aspect, and although it may be likely, I really didn't go through the water fast. But who knows, I guess it only takes a small amount of water in the wrong place. Bare in mind that the smoke only happened after the car got power again. It did not smoke up to that point. I guess it was clearing it's throat so to speak. I will try going on a little journey later today and report back.

Many thanks.

Hello all.

Well it's been a while I'm sorry to say Never been great at keeping in touch. And yep, you've guessed it, another problem. To start with, lets update things. After the service, Lexus said the car was as clean as a whistle. No problems with it at all which was nice to hear as it's got 130000 miles on it. As for the oil consumption, they said it could use up to a litre of oil every 1000 miles, scary. But I have done around 2800 miles now and I suppose it has used around a quarter of a litre of oil. I topped it up on Thursday and as before, it still seems to be breathing a little heavy, smoke from the oil filler hole, but no worse than it was when I got the car. As for the water, since I topped it up, it has gone from full to about a quarter full. Although when I looked at it the engine was hot so I don't know if that makes a difference. Of course I will now check it later when it's cold. As for the smoke, it got better and stopped smoking as the ambient temperatures got higher. I can only assume it was down to the cold weather. Which was nice. The car has been driving well, although I still keep getting an unbelievably bad flat spot in power at 2500 rpm when I accelerate hard, which I don't do often, but when I do need to, its a real pain. I can only liken it to literally taking your foot off the accelerator and then back on again. A total loss power for a second and then continues to take off like a scalded cat! It needs sorting if any one has any ideas.

So, onto the new problem. The dreaded Check VSC light with a warning triangle, the traction control light and a light that looks like and engine have come on. I live in Bristol and had to go to Croydon. Around 140 miles. I thought great as about 95% of my travelling is around town.So I got there no problem. I kept the engine over 2500rpm as much as I could all the way and the car felt great, didn't miss a beat. While I was there, a thunderstorm took place, lots of rain etc. On the way home, less than 3 miles, I drove through two large pools of water, not fast though. After the second pool of water, a couple of minute later after stopping at a roundabout, the dash lit up. OMG I thought, and then I pulled away with virtually no power at all. My heart sank. It would hardly rev above 2000rpm and was so slow I could barely keep up with congested traffic. But had to get home despite the 140 miles to go which filled me with fear. Once I got moving it wasn't so bad, keeping up to 30 or 40mph was achievable although even the slightest hill slowed me down. But I made it to Chieveley Services at J13 and decided to see if turning the engine off would help, or not. I couldn't take driving at 40 to 50mph on the motorway any more. Don't ask my why, but I stopped the engine, without my foot off the clutch I held the start button in for 10 seconds. I've no idea what possessed me to do this. Or why I repeated it 3 or 4 times. I started the engine again and gave it a few revs. Still seemed the same. Any way, we went into the services and went back to the car about 15 mins later. I started the car, left it ticking over for no more than 30 seconds before the engine cut out. I looked at my already terrified wife and thought omg this is it, dead. But I started the car again, it kept going, and I pulled away. And much to my surprise and amazement, and despite all the warning lights, I had power again! Like nothing was wrong. I made it to the motorway slip road and noticed an amazing amount of black smoke in my mirrors, so bad you could hardly see anything behind. My heart sank again, thinking maybe turbo blown. Literally as I joined the motorway, it turned into a car park and we were stationary. A few minutes later the black smoke stopped. And I still had power. After I think almost an hour of stop start, we got moving again and the car was fine, full power all the way home! I kept it between 2500 and 3000rpm all the way and it didn't miss a beat, and no more smoke.

I started it this morning and again all the lights on , but still had power. I had read about the fuel cap, so made sure that was tight, but still the lights are on. I disconnected the Battery, left it for an hour and have just reconnected it. All lights have gone out and all seems normal. Crazy car. Is this all pointing to the DPF on it's last legs?

Cheers

Hi Gaz, it now has 130k miles. It's just the last stamp was 120k miles so new engine has 32k miles. I've only done around 400 miles since I bought it though. And yes, I know it's over due a service and fingers crossed Lexus won't hold that against me. I am going to book her in tomorrow and I will let you know how I get on. Cheers.

Helloooo, When I brought the car I had the service book with all the Lexus stamps up to 120k miles. But I didn't have any supporting paperwork. I contacted Lexus Cardiff where the car was serviced and after much talking they did say they had put a new engine in. at 98k miles. But they couldn't supply any actual copies of work done, although they did send me a list of dates the car had work done. But that does not give any real info. I have also contacted the previous owner who happened to be a business and said that the car never wanted for anything. The person who drove the car at the company apparently loved the car. They were very nice people and are looking for the supporting paperwork for me. so fingers crossed if there is an issue it will be covered.

Cheers Gaz31,

I have started this again in the "Lexus Owners Club → Lexus Models → Lexus IS 250 / Lexus IS 250C Club / Lexus IS 220D & IS 200D Club → Engine & Transmission" section

Hope this is now correct.

Cheers

Hi all. I fixed the windows thanks to a post started by "nidgemo"

Hi all,

Firstly I would like to say how great it is here! Fantastic info, I have learned allot indeed.
Well I've just got my self an IS220D SE, actually got it on 23rd December 2013.The car is 2007 with 130k miles but one owner and full Lexus history up to date. The car had an entirely new engine fitted at 98000 miles in May 2012 and as such I thought I would be safe from the known engine issues. But I'm not so sure I am safe! So I will explain my situation. I have never owned a Lexus before and was more than happy with the test drive. Compared to my old Rover 75 diesel it was
amazing, lol. But as with all my cars I put a high flow air filter in so the engine can breathe more efficiently.

So I got a K&N air filter and fitted it. The filter I took out was so dirty you would not believe it! I even had to hoover out the air box as there was so much crap in it. The difference was amazing, it felt like I just bolted another 50 horses on. I was amazed to say the least :D

Well, this was two weeks ago. And the engine feels much better again. Much smoother and pulls better. But I have noticed my fuel consumption has gone down. It was around 31 mpg now is hovering around mid 29mpg. I did take the Battery out so maybe the computer is sorting it self out? I don't know. I always use Millers diesel additive as well. The car is still smoking, it only seems to smoke when I am at idle almost exactly 3 miles from my place of work, on my way home, in the traffic at the same set of traffic lights. Never smokes on my way into work. The smoke seems to vary in colour, whiteish to greyish to blueish to brownish and not in that order. It lasts for approx 1 min. Then clears before, or as I drive away. A few days ago I was on the motorway for a short time. I think I was in 2nd gear and I floored it, took of really quick and then it stopped accelerating for a moment and then accelerated again. It was like I took my foot off the accelerator momentarily. Very odd and very disconcerting. Now at the time I cleaned the EGR I checked the oil, it was half way between the high and low marks. Today I checked it and it is only just on the bottom of the dip stick :o And I checked the water and it was well below the minimum :o :o

I'm thinking this is all adding up to bad news indeed. But I don't understand it having problems on a replacement engine that's only done 32k miles.

Well thanks for reading, and I appreciate any comments and feedback. I am booking it into Lexus next week as it's a little overdue for a basic oil and filter service (£208 ) Is there anything I should be asking them?

P.S. After I disconnected the Battery, only my drivers window works. Anyone have a solution?

Thanks again.
