My 2004 M3 Coupe with 60K miles has recently developed a vibration/shudder right around 1800 rpm. It feels like something in the drivetrain is out of balance and causes a vibration.
This happens in gear, and can be felt while accelerating and decelerating. It's most noticeable when i'm slowing down and my foot is off the gas pedal the revs drop past 1800.
It seems to still be up there even when the car warms. The car is pretty much stock except for the exhaust... Did a scan and no codes came up. Car idles like **** on start up due to the shot MAF sensor and runs perfectly otherwise.
Through the process of elimination, I'm thinking it might be that the flywheel is somehow out of balance. Others have suggested having a look at the clutch...
I’ve already done wheel alignment and balancing so this eliminates the wheels, also changed section 2 of the exhaust and the muffler which also eliminates the exhaust and its rubbers involved. I also checked the guibo and the driveshaft and they seem to be ok.
The only thing left is the clutch and flywheel… can it be?
Any ideas or suggestions as to what this might be?
