Weird, mine has started quitting when the A/C is on and the fan is switched to like the #2 setting. Moving it to the #3 setting it works fine. It doesn't seem to do that with the A/C off so I'm assuming it's somehow related to that, maybe a leak somewhere in the A/C/Heater plumbing somewhere?

I had a Volvo 240 DL that was noisy the way you describe and it never did fail all the years we owned it, dk about bimmers though.
