What issues are you having with the A/C? poor cooling at idle....poor cooling overall or no cooling? Did they say the system has a leak?
More than likely vacuum pump is working properly though the seal that's between that an the engine is failing. Unless you have a symptom of poor brake assist. The quote is high for the vacuum pump because the BMW techs are instructed to remove turbos and other items which is not necessary.

The cooling was absolutely fine, but they were finding the leaking freon gas through AC vent, as my car is covered by a warranty so service advisor has changed the evaporator. Yes, you are right that BMW techs are asked to remove turbos to get access to vacuum pump. I have seen DIY in forum where a guy changed it on his x6m.
Vacuum pump and evaporator is taken
care by warranty. Now I am waiting on rear air shocks. The car is sagging on the rear but as soon as the air compressor is on , it sits fine. They couldn’t reproduce the air shock issue in front of warranty inspector. Hopefully they will be able to demonstrate the issue now. How long it takes the car to sag completely, if the car is not started ? Any ideas?? How to reproduce the sagging rear issue
