Finally I bought A 2001 M3 and got rid of 330I. Some questions.
It is truth that is normal to have some noise when shifting gears. It is like a "clap" sound. The dealer told me that all M3 have that sound.
It is the M3 noiser than the 330 (can you hear the engine louder)?
Please any of you guys with experience teach me about that
thanks :chair: :nixweiss:

What you're hearing is the famous BMW clunk noises. Since the version of the Getrag trans. we have is not the best out there (not as good as the one found on the M5), the clunks are more pronounced.
I don't find the M3 loud, unless I'm full out accelerating... and then even it's not toooo loud. But remember, it's not meant to be a quiet econobox...

Pretty much every car that I had that came with a getrag had the "signature" clunk. Nothing to worry about :thumbsup:

Welcome. :wave:

What you are hearing is called driveline lash, usually heard at lower speeds. (A good example is in a drive through line at a fast food place) When you release the clutch quickly, your driveline componets still have energy stored in them, the clunking/ratteling noise you hear are the componets bouncing around, dissipating the stored energy.

That is inherent of all manuals, but more pronounced on some cars than others.

Trev, do u think this might be seriously looked at in the new E90M3 as this version will have a lot more power than the current S54?

It may be. Its normal of all manual cars. It's just more noticable on ours.
