The a/c would just cut off and no matter the setting it wouldn't come back on until it wanted to, I never thought to look it up as the a/c would always start to blow again before the end of my trip. Know on to the question, Have we gathered more info on the best FSU to purchase someone point me in the right direction or should I just go to my dealer?
A Behr FSU from Autohaus or another supplier is $52. Putting aside where Behr makes their FSU, I'm pretty sure the replacement part that the stealer sells is over $100...someone can look it up, or I can check, I'll be at the stealer tomorrow.

Unless BMW has switched to Bosch for the replacement part for some reason, then Behr is/should be sufficient. If my new one fails, I guess I will replace it with whatever the stealer sells.
