I am extremely happy with the service ECU testing provided. After some careful research online I decided that I would send my Audi A3 instrument cluster for Inspection following an intermittent fault with the immobilizer, which is located inside the cluster. The online form makes the entire process so easy, even down to arranging collection from my home. Communication was excellent with regular updates at every stage. ECU testing identified a fault and gave me the option to proceed with the repair at a very reasonable price . The return of the cluster was quick and on time and has to date, worked perfectly! I might add that the cost of the repair was a small fraction of the cost of replacement and reprogramming the entire unit. Many thanks to the ECU testing team for a really top notch service!
