Hi, my sons B6 S4 just returned from accident repair centre with numerous electrical faults.
Engine is running rough,oil warning light on. rev counter and speedo not working,indicator repeater u/s
all dash lights not working,radio not working,key fobs also not working.Car had slight dent to be repaired.
If welding used to pull out dent, would an electrical spike cause all these faults or is it possible they were caused by battery being
disconnected for an extended period?
Repair company sending car to Audi to diagnose.
