I had a knocking sound in my B9 A4 when driving on bad LA surface streets. I took it to the service center and they were able to identify and fix the problem. This is a 2017 CPO with 9k miles. I'm new to the Audi family and was wondering if this should be a red flag of any other potential issues later on? This sounds like it was a fairly big problem, or is it not that big of a deal?
Tech notes: "Raised vehicle on hoist with assistance of second technicianand found transmission mount is missing securing nuts for transmission mount to transmission tunnel brace causing transmission to lift with torqueand cause knocking noise. Installed nuts for transmission mount."
