I took my car in last week to get two interior door handles replaced that the gray finish was wearing off. Noticed a moaning that morning. Asked them to check power steering fluid. A boot had busted leaking fluid. They replaced the steering rack. Took the loaner back today and got "Gunter" back- car has a man's voice. Glad to be reunited. SO much quieter than the e90 loaner. Rides better, too. Less like a truck ,lol.
