Ecutesting Reviews 871

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.

Società serissima, 5 stelle sono poche
In concessionaria Mercedes mi avevano chiesto 2130€ per la centralina cambio automatico, con 1 anno di garanzia. Mi sono rivolto alla Ecutesting, e con 315€ ho la centralina ricondizionata con garanzia a vita. Tutto meravigliosamente perfetto, dalla spedizione all'assistenza, imballaggio, tutto perfetto. Grazie

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.
