View Full Version : E46 running in problems - please help!

Mon, Sep-06-2004, 08:40:57 PM
Just bought a brand new E46 M3. It's great. Got a bit too enthusiastic and 'accidently' took it to 9000 revs. It's only done 80 miles and when I stopped there was white smoke from the engine. I've only done this once and the smoke has now stopped. May I have done some permanent damage? Too embarrassed to ask my dealer so wonder if anyone can give me some reassurance???? Please help.

Your not suppose to exceed 104 MPH or 5500 RPMs - also, how did you go all the way up to 9000? The limiter is set to 8000 I believe, so unless you mis-shifted theres no possible way you got that high. Permanent damage? Ask Art.

You did not hit 9k unless it was this on a downshift overrev?. Not possible without software being modified. What tranny do you have?

No offense, but why do people do stupid things like that. I guess it's just the thrill. I hope everything turns out good for you, take care.

it's a manual. I don't know the exact revs but the engine cut out. As I said it seems to be running ok now and there is no longer any smoke. A bit noisy, but i think that is normal. What sort of damage would i expect if there was to be any? Will they be able to tell at the running in ckeck up?

Valve train problems and bearing problems can be caused by over revving. You should be fine. Just follow the break in procedure until you get your 1200 mile service. There are a few guys that run software that allow 8800 RPM shift points. I don't recommend this without added strength to the bottom end and upgraded valve train components.
