I really am curious if this is an x5 issue or the 6 cylinder vs 8. This is what I get for buying an american made BMW LOL.

thats part of your problem. the ac is least effective at idle, and with the vehicle not moving, you're not getting air flow through grill to take the heat away from the heat exchanger. and this applies to all cars.
