02 tdi auto. Car cranks and fires but stops as if in immobilized mode but the ONLY light on the dash working is the battery light. I had it hooked to another car with cables but no help. Can it be in immobilized mode without any lights showing? I hooked code reader (not vag com) and it didn't see any codes. I put a new 109 relay in it with no change in performance. Fuel needle doesn't move, power windows don't work but interior lights do. Nothing on dash or radio aside from battery light
