I got a mercedes w221 s500 2006. 6 months ago I got those famous p0016 p0017 p0018 codes. I then change idle gear and chain and those that the chain runs through. I also changed all magnet sensors and of course new oil. But i still got the same codes after all repairs. Can it be the ecu? Three mechanics have check everything and all is in perfect order. They used the right disgnostic program and checked that all was line up. The car was working perfect before all repairs and it still works perfect after. But still those p0016 17 18 codes. Whats wrong???
