Registered User
hi i got audi a3 2.0tdi bkd dsg with the glow plug light flashing i had it diagnosed with vcds and its says G28 sensor no signal the fault code was p0322 i change the sensor and now its coming up with the fault code p0321 implausible signal and the engine is hard to start so i change the sensor again with a genuine audi one replace the wiring now the problem is still there until warm the the light goes out and it starts ok but it stalls when going into drive or reverse the cam sensor dont read until its warm could this be the problem thanks
