Vibrations around 1800rpm in neutral
My '06 325i has slight/mild vibrations coming from the engine. The vibrations start around 1800 RPM and the frequency increases as the rpm's increase. This happens even when the car is in neutral and stationary, so that rules out brakes, tires, etc. No check engine light. Nothing obvious sticks out when I look under the hood. Car has 135k miles on it.
Any ideas? Anything I can be checking? Thanks! Last edited by tom9192; 12-31-2017 at 12:36 PM.. |

Never heard of that, grease in dmfw?? It looks like it's from your throw out bearing, if you look at the grease, it's from being pumped out of something stationary. There is no way grease will look like that in a flywheel. The centrifugal force, and the heat will liquidify the grease and throw it across the flywheel. If any grease was to make contact with your clutch, it would burn it up, possibly slip. Your vibration is either from motor or trans mounts. Bty,the flywheel is balanced by removing/ adding steel.

Replaced with Valeo SMF kit and the vibrations are gone. Couldn't be happier with the SMF either. No chatter, feels smooth, and happy that I won't have to replace it ever again
