Hi to all I'm looking for any info as to why my q3 2013 tdi wont start after an accident I've replaced all airbags and had the airbag ecu repaired, I can't find a blow of lead any where, even asked the dealers, it keeps blowing the ecu fuse in the engine bay and the airbag furs in the car, both are 5 amp fues, on other cars it was just a matter of replacing the battery/ air bag lead, any help would be most helpful,
