When accelerating my 330i Automatic away I get a vibration and noise at seat level at around 25 to 30mph.

If I accelerate very gently I hear and feel nothing.

Over this speed no problems.

Drive shaft has been checked and is ok, any ideas

Thanks

can you get the codes read from the gearbox?
also check the rear trailing arm bushes and subframe mounting bushes for excessive movement
