There was no issue with the work done. The Fiat airbag ECU was returned fully functional and working with all faults sorted. I re-fitted it to the customers car and there were no faults requiring cleared afterwards. It all just worked and I re-assembled the dash and called the customer to collect. The cost was not unreasonable and the arranged postage all clear and straight forward (I chose to drop off the unit with the courier in order to speed up the process). I have given the service 4 out of 5 as the turnaround time was slower than advertised and the customer had to wait longer than expected to get her car back. However, I cannot fault the technical repair carried out. I will use the service again without hesitation and have confidence in their ability to effect a successful repair.
