I have posted this problem separately here:

I would appreciate if you guys read and tell whether experienced the same problem and how to solve it.

In short, while a trailer electric outlet is attached (regardless what trailer), the air con goes off and comes back only when the plug is taken out.

Please help, soon I will be cooked tender in the E70

BMW guys have no clue what the heck is going on.
