^^^^yep. thats why you put it on a lift somewhere else and look for yourself, then go to bmw and tell them you want the inspection. thats what i did. i actually had mine done a few months before the lawsuit was settled. took about a week from dropping the car off to picking it up. the free loaner was a piece of shit g6 though.
