I keep getting messages that I need to charge battery even after some long runs ie 250 miles in 2 days ,3 days after run battery voltage was 11.7 volts told by dealer this normal anybody else had similar problems.
I have a 2025 A3 the rear near side disc has been rusty since collection.I took the car back for attention they drove up and down hammering the brakes which partly cleared rust but it returned within 2 weeks anybody had similar problems.
