Update on Mini:
It is power steering fan, and it is draining the battery dead. Fan runs, pump runs even after engine off. Some temp switch or something is stuck. That is as far as the shop got.
The shop also refuses to install any of my supplied parts (even genuine Mini ones), so diag is all they will be doing, then I will send the car elsewhere to have the large amount of work done. I get cost on parts, I am not going to pay crazy markups.
