Thanks for the help will definitely give it a go

I think i have similar problem with my is220d. Its a 57reg with 85k miles. Sometimes it smokes alot will changing gear and accelerating from traffic lights. Somedays it hardly smokes and just see some puff. Oil and coolant level are fine. I think its the dpf. Will using wynns dpf cleaner help to clear the Dpf? Money is abit tight any suggestion.

I had the same problem with my car (injector 1). Seems like pretty common fault with diesel cars. I got my fixed locally in Leicester at Welham Motors for £100. Lexus dealership quoted me around £400.

Congrats Black suits the car
