5 minutes into driving away from the dealer, I hear a banging noise coming from the rear suspension. WTF, I turn around, the service manager takes it for a test drive and agrees with me that something is not right. I am waiting in the service area, I see a bunch of techs hovering over my car. Service manager and Saleperson come up to me and tell me they need more time to trouble shoot the issue. Sent me home in a brand new loaner A4 until they figure it out. My 2nd Audi, don't make me regret it please....
