Sent my ECU in for assessment for a misfire in cylinder #2. I was kept up to date with progress. and was informed the ECU needed repair. ECU fixed and returned promptly. The fault is now fixed and the car runs well. Would recommend this process if you believe ECU is at fault or you have exhausted all other options.

What an excellent service. YouTube tutorial showed how to remove the gear selector, filled out the online form, parcel collected and updates received every step of the process. Would highly recommend these guys. They know their stuff, and saved me an absolute fortune. Thank you.

Easy to follow instructions to send and receive item back also to follow progress on line. Delighted!

Everything was carried out as stated on your site. The van seems to run better than before the ECU was repaired.

Great pricing and fast service

I had a problem with the ABS system malfunctioning and producing a fault code. It has been overhauled by ECU Testing and is now functioning faultlessly.

I got my ABS module fixed which turned faulty due to faulty abs sensor on my Audi A4 B9 Model. ECU testing fixed my module and now my car is running good without any faults. They provide lifetime warranty on the fixed unit which is a big plus. The price was 298 GBP for the repair with taxes which i think is about 10-15% if i had to put a new abs module, therefore ended up saving good amount of money. many thanks to ECU testing. Big recommend!

The gear selector in my Range Rover failed and wouldn’t allow me to turn it. New ones were not even available for purchase at the time. I found ECU Testing online and they were great! I booked it in on their website and received the courier code, packaged up and shipped it. A couple of days later I got the report and cost to repair, made the payment online and received my selector back a couple of days after, now working perfectly.

ECU testing did a fantastic job from my first phone call to the fixing of the ECU and the delivery back to me in a very short time , fantastic service and would recommend them to others.

I appreciated their great service. They got the ABS Module repaired and done very quickly. They shipped it back very fast. The part was installed back to the car. Now the CEL lights gone and everything runs great as usual. Thank you!
