I have the same smoking issue. My 220d is on 119k. Took off the large diameter pipe leading from airbox to turbo to find 2 small pools of oil. The smaller pipe that is connected to the large pipe and leads to the top of the engine was also a little moist with oil. Also under the turbo is quite damp with gritty oil too. The car pulls like a train so I can't see the turbo being knackered. Any ideas on what to do next guys? For some reason it wont let me upload pics, saying server issue.
im based around Newport NP11 area if anyone could meet or advise where I could take the car that isn't going to cost an arm and leg
