I bought a A3 1.6 TDI (59plate) couple of weeks ago. when the car comes it came with 1/2 tank diesel. when i fill it for the first time i notice something on my dashboard. the DPF filter light comes ON when I put my keys in and it goes OFF when the engine starts.
also some times i do here a beep sound when I start (not always), no warning lights stays once the engine starts
