Fantastic quick service, well informed, great customer service & great value Fantastic quick service, well informed, great customer service & great value 5/5

After being told I would face a bill for over £2000 for my intermittent fault on my Auto transmission I did some 'googling' and found this company, I gave them a call and spoke with a well informed person regarding the service and options. They keep me informed almost daily with the progress of my part being tested/repaired, it was returned within 5 working days and has fixed the problem at a fraction of the cost! Highly recommended. Thanks


This company makes things nice and easy to follow and I cannot fault the service provided. Suffice to say they saved me over £1000 after reputable garages/dealers said it had to be a new gearbox. I would recommend them without hesitation. Thank you.

Good but slow Good but slow 3/5

Great repairs and well in formed of progress on most occasions but the whole process from posting to return needs speeding up, 10 -14 days is too long

A Class W169 Gearbox ECU Repair... FANTASTIC SERVICE! A Class W169 Gearbox ECU Repair... FANTASTIC SERVICE! 5/5

I have been really impressed by ECU testing and would definitely recommend their service. We had an A-Class w169 with the dreaded speed sensor fault. Communication was excellent from booking to return delivery we knew exactly what was happening and when the part would be returned (down to the hour), Repair time was 8 working days. So far the car has been perfect since the repair, total cost including gaskets, oil and repair was less than £3

B - Class CVT going into emergency mode (report to workshop) B - Class CVT going into emergency mode (report to workshop) 4/5

ECU Testing were very helpful at confirming the diagnosis. The part tracking is also good, in that it gives you confidence the ECU unit has been received and progressing through the workshop. Turn around time was rather disappointing @ 8 working days, as my car was off the road for almost 2 weeks. Albeit the current advised turn around time was 8-10 days. Better pay you £200 than the MB Dealer who wanted to fit an exchange g/box @ £3,500

Awesome! Awesome! 5/5

These guys are awesome at what they do. They have found their niche in the market and operate it to exceptional standards. I was struggling to get my problem fixed with local mechanics or Mercedes themselves and I cam upon ECU Testing's site when researching others who had the same problem. From start to finish, it felt that these guys held my hand through fixing my gear box and keeping me up to date on every single milestone! Thanks!
