The simple solution would be to ignore it - but I can't!
The gear lever in my M3 buzzes. It used to do it a bit, now it's doing it pretty well all the time. Driving me mad!
With the exception of the gear nob, EVERYTHING from the gearbox selector rod back is new. And yes, that includes the little rubber/sponge bush thing that goes inside the knuckle that attaches to the selector rod.
Oh - and if i take the gear nob off - the lever still buzzes.
I never felt that it was coming from the gear box itself - the noise just sounds to high frequency, but obviously now, I can't think of any other option.
The engine was out only a couple of thousand miles ago, and I do not believe that there is anything wrong with the engine or gearbox mounts.
I don't think that the gearbox oil is old or low, but I suppose either is a possibility - could a rattle in the selector forks be a symptom of low or old gearbox oil?
Could something rattling in the box be transmitted into the gear lever as a buzz?
What else could it be - any ideas?
Many thanks.

Does it go away if you hold the gear stick or push it forward or backwards into the gate?

Yes - but then it is such a light buzz, you'd expect any contact with the gear lever to suppress it. I'm getting into the habit of driving with one hand on the gear lever - not good!capnmchl wrote:Does it go away if you hold the gear stick or push it forward or backwards into the gate?

Might not be your problem mate but when mine did this it turned out to be a broken bit of "stuff" inside the knob. Changed the knob, buzz went away. If you've got a spare it s worth trying.

It's a broken spring in the gearbox, very common on the M3 box, unfortunately BMW have made this part NLA. It's a box off job to replace, I am looking at getting springs made up as spares, but have yet to find a supplier.

You sound very certain. Is a broken spring consistent with my buzz starting out as very occasionaly and then developing to all the time?

Demlotcrew, as a matter of interest, which part number is it?
