Excellent Service 5/5

The repair of my Instrument Cluster was done promptly. The reinstallation instructions were very helpful and everything on the panel; tachometer, speedometer, LCD display is now working perfectly. The most surprising fact was that the technician called me to discuss the repair and whether I had any questions. I am from the USA and it was great to hear the British accent. Highly recommended by me.

Excellent Service 5/5

I used ECU Testing to repair my dashboard instrument cluster. I found them online and was very pleased with the service. I received an email saying they had received my item and when the part was ready they called me to say it had been repaired and they were sending back. The turn around was a week which was good.
