My Ride: BMW 325ci e46
Driveline rumble, fluctuating revs at low rpm

Hey guys, this is my first post.. However I'm not new to e46 fanatics as I have spent some time trying to find the solution to this problem no mechanic (including BMW) can work out.. So here is my problem..

I'm experiencing a vibration/rumble down my driveline..
Apparently the guibo, diff, and transmission including gearbox are all fine according toy mechanic..
On an even throttle around 1400 rpm it seems my revs are fluctuating.. In other words, the revs jump up and down..


So far I've been told its not bearings, not guibo, not gearbox, not the maf..

The symptoms I'm experiencing may not be related, but I thought I'd include them in the same post..

C'mon guys, I need answers!
