Anyone heard of a timing chain issue in the S63 engine?
My M is at the dealer for new injectors and plugs. Those are squared away, but it keeps going into limp mode when driven even gently with an error related to the timing chain. They say the cam shaft and crankshaft aren't in sync. There is an audible clatter at idle, which it has had since I bought it, but I thought was normal. Was throwing this code when it came in. They have to pull the motor to check the timing chain. They are saying it could be a timing chain tensioner gone bad or a chain guide or the chain could be stretched and jumped a cog? Ugh! Shoot me now!
