2008 328i engine stalling
I have a 2008 328i with about 86k miles on it. I have noticed recently that when I have the car in drive (its an auto) with my foot on the brake (like at a red light), the car seems to be struggling to not stall. The revs will drop too low and the engine will start to clunk for a breif moment before revving back up to normal. Aside from this, the car seems fine.
Any ideas what could be causing this? Should I be concerned about a serious tranny issue?
