Excellent service every step of the way 5/5

Mazda 3 DSC issue. Sent the ECU to ECU Testing and received a first class service. Updated by email and text every step of the way and fix completed within the timeframe quoted. Fault resolved and Lifetime Warranty gives peace of mind. Thanks ECU Testing. Would recommend!

Truly exceptional service 5/5

I cannot think of another company that I have had such good service from. They really know their stuff and are very friendly over the phone. My TT cluster was fixed and back to me in under a week.

Amazing company 5/5

DO NOT TRUST 0/5

PLEASE DO NOT TRUST! Had to sent the unit three times and at the end the could not repair it! According to them was working fine. I showed them a Vauxhall report from their diagnostic computer, paid at my expense, they told me, it was just a screen-shot and they do not want to reimburse me, even though third policy says so, because suddenly they require a technical report, which obviously I have to pay for again, plus all the problems they created.
