Hi Gary, I can't believe this is still ongoing buddy, you must have spent quite a bit by now! Be mindful that you don't spend over the cars value, plus all the hours you put in. I really do feel for you, personally I think the is220d is a money pit when things go wrong. Thumbs up to your perseverance, I really hope you get somewhere with this and sort it. Good luck buddy. Can't believe the Lexus techs can't solve this one, are they not the experts!? Sent from my iPhone using Lexus OC

Word of advice, avoid the is220d like plague unless you will be doing like over 20k miles a year otherwise I would recommend the is250 instead. I been driving diesels all my life for over 15 years the is220d is by far the worst diesel I've ever owned, never again! Good luck Sent from my iPhone using Lexus OC

So sorry to hear that I really feel for you. Even though I haven't got my is220d I have been following this thread closely as this car has puzzled me to the point of going insane. Keep us posted on updates, let's see what the makers themselves find! Good luck buddy I hope it doesn't become a money pit for you as it did with me. Sent from my iPhone using Lexus OC

You know if this fix works and stops the smoking and poor economy issues it could be very beneficial to other is220d owner out there who are having similar issues. Keep it posted once you get the work done. Sent from my iPhone using Lexus OC

£313 ouch! Hope it does solve your problems, keep us posted on the results. Good luck. Sent from my iPhone using Lexus OC

Hi Badger1966, I could be wrong but it maybe some of your injectors could be dirty, if they are then injector spray pattern would be effected hence it could be over fuelling therefore detecting fuel leak? Ask Lexus to check injector readings on diagnostics. I really feel for you as I recently got rid of my is220d, I realised that when this car runs fine it's ok, but the minute something goes wrong, it becomes a endless money pit! I really hope you get it sorted out, good luck. Sent from my iPhone using Lexus OC

Hi Steve, My work requires me to do a lot of motorway and town driving so yes your right heading to German or even British brand! As I had a Ford diesel before the Lexus and it never missed a beat! Sent from my iPhone using Lexus OC

Hi everyone, Just wanted to say thank you to everyone on this great club, for all the advise and the expert knowledge I wish I had looked at this club forum before I purchased my full Lexus service history dreaded 2010 model is220d. I owned the car for just over a year and I'm glad to say I no longer own it, even looking after it religiously and using shell nitro diesel it still gave endless problems and issues and made my wallet extremely light. The design of the engine was defective and flawed originally and ever since Lexus never got it right with that Diesel engine. I can't speak for the is200d but I can put hands on my heart and advise anyone against purchasing a is220d. It a shame that because of all the troubles I got from the is220d, it's really put me off the Lexus mark also the service I got from a few Lexus dealers were so poor, the minute you mention the is220d they don't want to know but are happy to take your hard earned cash! However as fellow members will advise that not all Lexus models are a dog like the is220d! Maybe one day I will return to Lexus but it will be a long time before my faith in the brand is restored. Thank you all again and goodbye for now. Sent from my iPhone using Lexus OC

Apparently it's true that you now can remap the is220d, I have spoken to a few reputable mappers and they have confirmed that the ecu is no longer locked as of a few months ago! Personally I wouldn't bother wasting time on the is220d, it's a heap of ******* engine design that has endless problems! Get rid of it while it's still running ok, that's my opinion. I got rid of mine just recently and I'm soooo glad I did! I'm sure other members will advise the same. Sent from my iPhone using Lexus OC

Rizzy, The gearing ratios on the is220d are very high so doing 60 in fifth may be ok for a while but your labouring the engine which eventually leads to problems. As for your shaking and juddering your getting now could be due to the egr valve being clogged up, it may have been caused by labouring the engine, I would start there. Hope you get it sorted keep us updated Sent from my iPhone using Lexus OC

I also have a 2010 model and one thing for sure is that the gear box isn't the quietest always been a little clunky, they are robust but it's a clunky one, not the best designed unit for quietness but you do get used it. As for the water pump, yes they do fail, some people have replaced theirs 3 times, mine just had to be replaced last week! See how it goes for you with Lexus, if your not happy maybe you can ask for them to take the vehicle back under sale of goods act, hope you get it sorted. Sent from my iPhone using Lexus OC

I could be wrong but I think there was an Ecu update from Lexus on the pre 2008 models which was supposed to help with this issue, it's something to do with the fifth injector dumping a lot of fuel during warm up or something along those lines. I'm sure someone will confirm my advice. I think you may need o check with a Lexus dealer on this issue. Sent from my iPhone using Lexus OC

Hi mate, I was going to say get your turbo checked out as I think the turbo is not active in 1st gear, hence why you seem to be ok in 1st, I believe the turbo kicks in around 1800rpm from 2nd gear onwards, so your problems could be turbo related, I hope other members will have a better input then me, I hope you get to the bottom of your problem. I would also get a decent code reader so that you can check when you get the MIL lights. Sent from my iPhone using Lexus OC
