Hi all

The 520d had a new clutch and flywheel in June and has done probably 500 miles since then. The bite point in the clutch was really low, and it was decided a new clutch and flywheel would sort it.

The other day the car has started to kind of bang going from 1st to 2nd and from 2nd to 3rd gears....doesn't seem to happen going into other gears. Bite point is still nearly at the floor, and the car also seems to want to drop revs and slow down very quickly. When you let of the accelerator, the rev needle drops down and comes back up, sort of like the car is braking. I thought it could be a sticking caliper, but doesn't seem to be.

Any ideas on what might be the cause? I know it's hard to say...it's gone back to the dealer, but it'd be good to have an idea of the cause.
