Hello!
Sometimes our BMW makes odd sounds from engine. I swear that I hear chain sound sometimes. Is it ok? It sounds like the chain is sliding on something, "ssshhhlllll". I don't know why it sounds like that? The engine is M50. Second sound is "pirrr" from the tailpipe (or from the engine?! No it can't be!), it comes when I raise rpm from idle rpm. What is that? Is it the timing chain or bad exhaust pipe?
BMW is driving me nuts! ;-)
