I had problems with the engine pollution warning it also resulted in a loss of power to the engine, it was put into the garage under warranty and the had great difficulty in fixing it. It was off the road for about 6 weeks and they subsequently replaced the turbo system and various other parts and it is now working. I dont know if this is the same problem you have encountered. the chrome handles I had the same problem and was told that this was a defect in the manufacture they have been replaced with other handles non chrome.
