Zitat von Jan-DirkWhich engine, where is the code being indicated?
A worn cam chain will either kill the engine when it finally ripps apart or it will cause rattling noises, it will not effect the starting performance.
Which engine? A VR6. The code is 00515, cam pos sensor G40, open or short to plus, intermittent. Read with VAG-COM. This mechanic said it starts to rattle when the strainer could not handle the problem, but in this case, it can. He said that a worn chain could give the dtc, and also start problem. I don't know.
