We were recommended by the owner of this Audi A4 who had no electric windows or central locking. He was told he needed a new convenience module however once this was replaced the issues were had not been resolved.
After a quick scan and pinpointing the nature of the fault, we had discovered that two of the wires in the drivers door trim had perished.
Where many garages and even the main dealer would book this vehicle for hours, we discovered the fault as well as a few other minor issues within half an hour.
We also diagnosed a faulty engine thermostat and a split dump valve.
Another happy (and impressed) customer!
