I have been getting multiple warning messages consecutively, including TPMS failure, Brake system failure, Parking brake failure, yellow engine warning light and dials flicking to zero and back, also stop/start system failing - this is the only system currently failing but cant drive it with dials moving and messages every few minutes. Been at Audi service for a week, multiple hours being clocked up (less than 3yrs old but 74,000 miles so out of warranty) with checking wiring and earthing. Audi now replacing management system gateway but not confident this is the problem, this could go on unlimited - anyone else had these problems ?
