Welcome Steve :)

not 100% on the series III GS but yes that is typically what is required. These downstream sensors rarely fail, unlike the upstream sensors. If you know there is an air leak that is the most obvious place to start.

No, no Toyota cars have that feature.

Friction from the floating calliper on the back of the pads should stop most movement, along with slide pin bush and dust seals, unless the pad clips aren't in place / tight and pads and calliper all move together. The RX TSB regarding the rear slide pins states that the top pin, without the bush, has a slightly larger diameter shank but I'm guessing the bottom one is as wide or slightly more with the bush in place. The TSB just clarifies the correct procedure - I guess dealers were either installing the pins the wrong way, using too much grease or using the wrong grease. I believe using the bush pins top and bottom can cause too much drag which means the pads won't properly release - leading to excessive heat and wear. Still if you have too much play anyway it could be worth a go, just check the temperature of the rear wheels after some journeys. Putting too much grease can also cause excessive wear as you get air sealed behind the pin when you push it in, compressing the air which will try and push the pin out again. That pressure keeps the pads against the disc. Using the correct grease is also important as certain grease will make the bush swell, leading to seizing.

can you tell if most of the movement comes from the top or bottom? I wonder it you could use slide pins with the bush top and bottom.

Only when my callipers seized. I freed them up, reinstalling the old pin minus the bushing for a couple of days until I got new pins and bush.

2 or 3 mm? There is something very wrong then. Incorrect sized pins or the wrong carrier. I could move mine but only about 1 mm.

They can if you want the warranty - it's in the terms and conditions. It is different to the new car manufacturer warranty which by law they have to allow owners to use any garage.

Toyota GB used to stop Lexus servicing from happening at Toyota dealers, but dealers seem to be getting away with doing Lexus servicing more and more. There is always the risk of head office clamping down again which may put dealers off providing a service plan that in a year or two they could struggle to honour. Certainly worth enquiring though. The main disadvantage you have is a Lexus extended warranty requires servicing to be carried out by a Lexus dealer.

It is a relatively efficient, high compression, direct injection, Atkinson cycle 2.5l engine. The electric motor will also assist somewhat providing some minor benefit. The cruise control is also tuned for efficiency and allows a couple of mph flexibility so unnecessary braking doesn't occur on downhills and aggressive acceleration is avoided on minor inclines. Push it above the speed limit though and the engine begins to work more and economic drops to what you would expect from a normal 3l engine. Conversely get stuck in some 50 mph roadworks and you can achieve 55 - 60 mpg on that stretch.

it was either taken out before the price hike or a service plan outside of an official Lexus one. A franchise/dealership could create their own plan and charge their own prices but this is something that Lexus seem to be stopping.

Engine revs are typically low when cruising. There isn't a direct correlation between speed and engine rpm as there is with a manual transmission or an auto transmission which has gone into lock-up. The CVT will rev the engine up or down depending on power requirements at any particular moment.

when was that taken out?

if you are actually sticking to 70mph then 55 mpg is possible, maybe 50 mpg with an F Sport or Premier due to heavier and wider wheels/tyres

you can get two or three year plans. The standard price doesn't offer any discount, some dealers may give you up to 10%. The benefit of the service plans are spread payments and you lock in the price at the start, so if servicing costs increase you don't pay any extra.

there was some discussion in the following thread: http://www.lexusownersclub.co.uk/forum/topic/93213-spare-wheel/

It is most likely the clutch and/or the flywheel.

The one good thing about the new servicing model is transparency now that Lexus have actually published the pricing on their website. Before then you just have to take your dealers word. The bad point is the massive increase in service costs without the ability to shop around.

yes you can but you need to make sure you get the right disc for the navigation unit you have. Easiest way is to check at the following site: http://www.lexus-mapupdates.eu/ then rather than order from Lexus get it from ebay. There are a number of sellers who split up the discs so you can get just the UK part much cheaper than purchasing the 4 disc update from Lexus.

E1A is the latest version available.

yes it was. For essential servicing the cost shouldn't be more than £349 for the major service plus £295 for the timing belt. http://www.lexus.co.uk/owners/servicing-and-maintenance/#/ServicingYourLexus

here is one example, higher mileage but newer.: http://usedcars.lexus.co.uk/used-IS/IS-300h/2.5-Luxury/Leicester/3627528-604603020-1609628.aspx?srcmdc=se_na_re_ and another: http://usedcars.lexus.co.uk/used-IS/IS-300h/2.5-Luxury/Stoke-on-Trent/3627528-604448877-1607044.aspx?srcmdc=se_na_re_ Just use the used car section on www.lexus.co.uk. Select just the Luxury grade, and sort the results by price. The site doesn't give clear information on what seats are included, either optional heated leather or the option on the optional heat/cool/memory leather. When looking at the pictures try and spot the heated seat buttons in front of the gear lever - you want the split two buttons for heat/cool rather than just a large single button for heat.

yes it could be related to the leak in the exhaust, depends how close it is to the sensor. You may be lucky and it was just a one off error but I suspect it will return over the next few days, it won't immediately return due to the nature of the fault.

the above doesn't save anything, other than saving from potential future price hikes over the next three years. http://www.lexus.co.uk/owners/servicing-and-maintenance/#/ServicingYourLexus

Lexus have published their harmonised pricing on the website http://www.lexus.co.uk/owners/servicing-and-maintenance/#/ServicingYourLexus
