Adam, sorry to hear about your problem. It shouldn't happen on a flagship 100K+ BMW. It sucks. How many miles do you have?
I usually start driving within 30 seconds. I also read that warming up is unnecessary and maybe even harmful. I suspect carbon deposits. Waiting and idling is also bad for the engine and environment.
