Repair/reconditioning of Fiat Ducato airbag ecu 5/5

I had an airbag ecu repaired by ECU testing in July 2026. The repair was carried out extremely quickly and efficiently, and the unit has been working as it should since re installation. Not having to code a new ecu was a bonus, as is the lifetime warranty. The on line form for repair was easy to complete, and I was kept up to date at each stage of the process. All in all, really impressive service, and much appreciated.
