Drivetrain slack..

[sixspeed]

Anyone else get a noticeable clonk when engaging/disengaging the clutch from standstill. Pretty sure this is the standard M-diff clunk, which is what it sounds like, although I'm thinking mine may have got louder in recent months...

Wondering whether to bother with a trip to the dealers, only to be told that "they all do that, sir"...

I have heard it called a number of things but the best description was transmission backlash. Mine has just come out of the dealers for a number of things and they test drove it and commented on it as "normal sir". It does sound strange though and when at traffic lights disengaging a gear it makes me sound like a novice. To top it off I then jerk up the road because of the CDV :lol:

Mine does it too...

I then jerk up the road

Andy, I also get this and it pisses me off! I have asked BMW to look at it, but Matt was off so had no update!

I get clonking when manouvering. The Z4s I test drove all had similar clonkyness tbh.

Mines done it from new, there's even a section in one of the manuals which mentions 'acoustic feedback' and 'clanking noises' due to the reinforced driveline.

I figured it was standard. A mate's M3 does the same thing. It's just only recently I've noticed it. Guess I've finally loosened her up!

Yup very normal...though only disengaging for me and not every time? E46 M3s do it too.

Yes it does.

And i love it! All those clunks and diff noises just give the car more character and i'd be sad if it went all "quiet"..
