| I have a 2004 M3 with SMG, I have about 10k miles on it I just purchased it from a dealer. I have never had SMG gearbox before and was thinking that the jerking problem usually when you take off (feels like you release your clutch too fast if you are driving manual). But after I test drove brand new 2005 M3 with SMG I didn't notice this problem. I took this car to the BMW center and they are claming that car drives fine and that jerking is normal for SMG because the engine is too powerful.
Another issue I have is something downshifting shakes the car and doesn't downshift as smooth as it should.
Anyone here had the same problem? Or knows what could be causing this? |
