My car is at the dealership for the third time in two years for AC issues (long story, it's not cooling the car down at all). For the third time in a row, my dealer says the "system was overcharged leading to high pressures - removed refrigerant and put the pressures back to spec and it works great now."

Well, fool me once and all that, but this seems odd given I haven't (nor has anyone) added any refrigerant to the system.

After reading a few threads here, this seems to be a somewhat widespread issue (though mostly focused on V8 cars, which isn't my case).

Has anyone else seen/had this issue? Any ideas on what would cause the system to be overcharged? Any questions to ask the dealer since they think they solved the issue (and I disagree)?

I also had a 2017 540 that had A/C issues. The dealer performed a software update and removed some improperly placed foam from the center vents. Once this was completed, the A/C worked much better.

It has always been an issue of the 17's. I went to the dealer multiple times but they just kept saying it's working properly and I just eventually have up. If you guys can figure out a fix I'm all for it. Maybe look at how the 19's are done because that one was strong. I had it as a loaner and said to myself this is how the ac should work.
