I posted this in a different list and didn't see any responses. Hoping this will see a larger crowd.
-----------------------
I've had a weird noise in the front left corner of my '04 R53 for a couple of weeks that started after a clutch replacement. When the engine makes the transition from accelerating the car to engine braking or from decel to accelerating, I get a clunking sound that is a little lower in pitch than two billiard ***** hitting.

A few notes:
The car has about 107k miles on it.
I just had a clutch done, along with LCS bushings.
The upper engine vibration damper was replaced at the same time
The lower and transmission engine mounts were upgraded to urethane after the noise started as I hoped it was the mounts that were loose after 100,000 miles.
The noise does not occur under braking
The noise seems a little louder during transition to acceleration than during engine braking
The same noise can be produced if you rock the car forward and backward shifting from 1st to reverse.

I'm concerned it could be a few things:
1) bad dual mass flywheel (clanking back and forth)
2) a loose flywheel
3) broken spring in the clutch disk
4) bad inner CV joint on the driver's side (no noise from outer joint in tight turns)
5) something going wonky in the differential

If I jack up one side of the car and move the front left wheel back and forth gently, there is some free play and I can hear the geartrain play. If I really crank on the tire back and forth, I can hear the noise which sounds like a short ringing sound. I can't tell if it's in the gearbox or the drive axle.

Has anyone had this problem? What's the fix?

Thanks for the help.
