E39 M5 and E52 Z8 Discussion
Hello,
I have a 2001 E39 M5 with the S62 engine. It rattles at startup and when I rev it to between 2000 and 3000rpm it kinda vibrates (misfire?)
I took a diagnose yesterday and found the code: "69 Plausability, engine temperature"
I've replaced the chain tensioner on the passenger side...
