Absolutely top Guys. Very pleased with the service I have received

From start to finish the process was so easy, the list of faults on the website gives you the confidence that the issue you have has been resolved many times before & gave me the confidence to trust sending my part away for repair, turn around was very quick & part returned in perfect working order. I honestly can’t thank the guys enough

My Mechatronics unit was suspected of being my issue on a Seat Ateca 2018. all fault codes pointed towards it being my issue. when i sent it in for testing the fault couldn't be replicated, but the chap i spoke to said that could be down to many different factors. I was advised i could have the unit re built anyway or returned for the test fee. i opted for the repair and fingers crossed its worked - So far so good they turned this around in the quoted 3 days and i cant fault them they kept me updated throughout the process. Fingers crossed it lasts longer than the previous repair (NOT ecu Testing). although now i have the lifetime warranty which was one of the reasons i went with them. thank you ECU testing

After a discussion by phone with ECU testing on an issue we were experiencing with a Honda Jazz petrol
with a permanent Cylinder no.4 injector fault code and misfire and all other area's wiring etc..explored and examined we decided to send the engine control module for testing. After a couple of days we were contacted by ECU testing to say that no issue had been found while testing but they could fully refurbish the unit. When questioned on how it was tested we were told they could not dicuss the testing procedure and we could not talk to technician who tested the unit. We declined the refurbishment and paid €95 for the testing and postage to send it back to us. This we fully understood and accepted at that time as reasonable for the time involved. However when the ECU was returned we decided with all other avenues explored and uncertainty with the testing procedures of the control unit we located another company in Ireland to test and eventually repair the ECU. They believed unit was never opened and wondered how the unit had passed the 1st inspection especially as the resistor/ transistor that controls cylinder 4 needed replacing. They replaced it and ECU was refitted. No fault codes recorded and vehicle driving perfectly. Contacted ECU testing to express my disappointment as I prefer to try resolve issues 1st rather than leaving a negative review. However my complaint was totally ignored and I found the gentleman i talked to most unhelpful and reluctant to offer any explanation.

The abs module failed on my 2005 E90 bmw. To replace this for a brand new unit just wouldn’t have been viable. Ecutesting tested the abs module and replaced the components that had failed, plus gave a lifetime warranty. Very quick turnaround and because it was the original no recoding was required. I highly recommend this company.

I searched within the US for a service that could and world repair our Blue & Me module for our Fiat 500. With no one available here, I found ECUtesting in the UK. The company made it so easy to for me to place an order request, ship, get the repair done, and return shipment. The prices were very very reasonable. I was also provided a warranty on the service. And YES ! The repair was perfect. I rate ECUtesting as a superior service and recommend contacting them first.

Did what they promised to do. Car now working perfectly.

EcUtesting made a valid repair to ecu, which let me add 60k miles on the vehicle. Unit failed again and ecu testing were not able to repair a second time, but lifetime warranty was honoured where they could have easily wriggled out of it. Top service, would use again, many thanks.

Amazing experience, quick response, job well done, quick return. And relatively cheap

Second time customer purely because the leap of faith first time letting these guys/gals loose on my 2006 Mercedes CLS320cdi gear selector which they performed a spectacular job still going strong with zero problems. My turbo actuator dumped my CLS into limp mode used my scanner to identify the problem and log the code. All information from my scanner and detailed description from myself uploaded via the online reporting form, collection arranged by Ecutesting using DHL. I was kept up to date with the progress via email/txt or logging in online to the main site. My actuator fixed and returned back to me again via DHL the whole process as before was flawless, the price I paid way cheaper than having to replace the whole turbo which would have cost 6 times more. Fitted the actuator this morning checked for codes with my scanner before I started the car fired up and ran with zero issues. Road tested and straight away notice a big difference in the smoothness a little further down the road nailed the accelerator hit the kickdown switch and the CLS just took off, if I had tried to do that before the car would had shuddered badly didn't do any of that just took off like a rat up a drain pipe. Actuator fixed and with piece of mind life time guarantee. I whole heartly couldn't recommend ECU testing enough thankyou you guys rock.

Fast efficient service I was kept updated throughout and the cost Was way below what a new part would have cost from a main dealer

After finding other services reported they were unable to assist me, I placed my reliance on ECU Testing. They quickly and professionally processed my module. When I installed it, all programming was intact and the unit functioned like brand new! Their price was very reasonable, their communications impeccable, and I would most highly recommend them.

I paid ECU Testing £695.49 on 10th June 2025 for a “no fault rebuild by request” of my DQ200 Mechatronic unit.

The unit was returned to me on 12th June — completely broken, with signs of shady adhesive used on the sensor leg. The repair was not only faulty but dangerous. I reported the issue within one hour by phone, and followed up with emails on 13th June demanding either a refund or a working replacement.

Instead, ECU Testing offered only to “send it back for investigation” — with no guarantee of refund, repair or replacement, despite the fact that I paid for a professional fixing service.

Their own email initially acknowledged the glue might be theirs, but later denied responsibility. I provided evidence, and they refused accountability.

I’ve now had to start a chargeback process via Monzo. The law is clear under the Consumer Rights Act 2015: if a paid service results in a faulty product, I’m entitled to a refund or guaranteed fix — not an open-ended investigation while I suffer the consequences.

So far, I’ve received no solution, no working part, and no refund. Just wasted time, stress, and a broken car.

I strongly advise others to avoid this company, especially if you expect proper service or honest aftercare.

Faulty gearbox ecu repaired quickly and with great communication as to where it was in the process. Delivery excellent too

excellent service speedo head repaired and returned very quickly - work carried out as promised on the web site could not be more pleased.

ecutesting repaired my faulty unit very quickly, saving me loads of money compared to having the main dealer supply and fit new unit. What's better is the repair has a lifetime warranty, gives you peace of mind knowing the repairs done professionally

Fabulous from start to finish. Great communication. Happy with the price. Don’t know what they did but I sent an unreadable dashboard full of hieroglyphics and got back one which works perfectly.Chuffed. Thank you.

My mechanic told me my PCM was defective and replacements were no longer made so the entire car would be classed as unrepairable and therefore only worth scrap! We took the PCM out and sent it to ECUTesting who tested, repaired and returned it in less than 5 business days. With the PCM reinstalled my car lives again! ECUTesting saved the day!

Oh and the cost was only a third of what a replacement would have been (when they were still being made).

Got the repair done as fast as reasonably possible. Kept me informed of progress. Excellent!

Used ECUTesting along one other repairer for years. ECU testing have biggest coverage. Online order form is effortless and easy to fill. Postage labels emailed to be printed. Automated text or email updates very helpful tracking the progress. Saved loads of money for our customers.
