sounds like the same thing to me... http://www.xoutpost.com/x5-e70-forum/...ight-bump.html

Today it happened twice at red lights. Regular stop - I release the brakes on green and it chokes forward slightly (not an engine thing at all) before I give it any gas... if I gas quick the results will probably be worse as something is still "caught" in the brake process. And no, autohold isn't on.

It sometimes feels like the anti-rollback for hills feature is sticking even on plane ground.
