Dont go to the dealer. I went and had mine done, re-charged plus leak test w dye at Car-X three weeks ago. X5 takes .98 lb of freon so they charge me $89 including tax. Cheaper than any other shops. ex: PEP Boys, Firestone, etc/
The current hot summer in Illinois, my car is parked outside all day at work, I run it 3 blue dots on temp wheel and 1st bar in temp control.
My car gets brrr.. freezing!
