Hi everyone i have a 2001 A3 1.8t with a few fault codes ( I have VagCom ) the main one which is ****ing me off is the pressure drop between turbo and throttle valve CHECK DV !!!! I have checked all visible pipes checked the N249 pipes under mani when i changed crappy plastic dipstick! Only thing i can now think of is my DV leaking maybe or boost gauge pipes split ???
Other Faults are 02 sensor which i replaced last year ?? And cooling system failure ??? Thermostat ??? Not the coolant temp sender replaced that last month !!!
Any suggestions would be ideal.
