Hi, Just wondering if you got the 5th changed or cleaned and if it made a difference, I have a smokey IS220d and heavy on diesel. Thanks Paul

Hi, I have a 2006 IS220d and have a similar blue smoke issue, the DPF threw up an error 3 yrs ago so i took it out and got it cleaned by a company in Tyrone, no DPF issues since. it has never burnt a drop of oil since the day i got it. The smoke started maybe 5 yrs ago but very little at first and it progressively got worse, dont think it was anything to do with the DPF, there is always a smell of diesel now when i stop at a junction etc.and theres no smoke until it warms up, i think there is less smoke on warmer days. i had 2 injectors with large leaks so i replaced all 4 injectors with injectors from a scrap yard about 2yrs ago and ive no injector issues now. I also changed the DPF differential pressure sensor twice but no difference, other than the blue smoke the car runs well. There is over 415,000 kms on the clock as i was doing long commutes for years so i frequently gave it the high revs motorway dpf burnoff. It is passing the NCT also, i give it a dpf burnoff immediately beforehand just in case. I read in a seperate forum from one guy that his wiring from the dpf differential pressure sensor to the ecu was broken and when he fixed it is solved the smoke issue, but surely if the wire was broken the car would throw up a fault, i unplugged my sensor and it threw up a fault, i also swapped the pipes and it threw up a fault so that would suggest the sensor is working ok. Mine is the exec version, fully loaded and going well so id like to solve the issue and keep it instead of selling it as it. Anyone have any ideas.
