Beware of backstreet garages. Backstreet garages simply do not have the technology needed to pin point exact ECU faults on the most modern of Audi vehicles, they may fix a problem that actually wasn’t the problem and then you end up journeying back to the garage with the same ECU fault, costing you even more money. At A1 Diagnostics Audi that does not happen we find the exact ECU fault and get you out on the road quickly and efficiently.
