Also moniters the electric mirrors. Windows etc. All thats in the car.
If its playing up might have some water in it.
Dont know if mk4 platforms suffer from damage that way but if it does ive got one sat on my kitchen side as I bought the wrong one for the passat
ok, all windows, mirrors, locks etc seem to work fine (passenger/boot only work when close to car, guess thats battery related rather than module), why the fault, or could this be an old fault? pretty sure they said they cleared all codes but might do a complete code clear later and scan again, until today have just done scans on the engine and instruments rather than using autoscan.
