gethin postr the vag com codes omn here..i now one was engine misfire detected..and i could remember the others.. is the car obd1/2 , has it always been a vr? ,when did the fault start..like i said before , sometimes you have to work backwards, even if it means refitting all the old kit.. but if youve done everything we talked about, then maybe the ecu's having a bad day ?? but im sure c2 can help you with that.
