When I put it in gear it lurches forward (or back if in reverse) and is very dangerous. The only way I can stop it is by placing into neutral and giving the engine a rev which seems to resolve the issue. It only happens when the engine is cold.

He mentioned BMW is aware of the issue and it is referred to as "vehicle hunting on cold start" and that there will be a flash update due in July to fix it on the 325 and 330's. I have had him place me on the notification list so when the fix is available I can get the flash update done next month.

Thought you might like to know if you are experiencing the same problem....

Have a good one...
my 335 cold starts at 1200-1400rpm and then drops to 600rpm as the exhaust flapper opens, normal?
