I had a non start issue with my car, after doing plenty of in depth diagnostics I concluded that the engine ecu had a major … More issue, I went on line, and found ECUconnection put in my ecu details and they had a replacement available for next day delivery, which in all fairness it came a day later, but that was my fault due to the order cut off time. Anyway, the ecu was very well priced, very well packaged and it has immo off which means it will work without having to code it to the car, I connected it up and immediately had the car running.
Excellent service, would certainly use again in an instant.
Thankyou very much

Brilliant service from ECU connection. Dry solder joints were giving my car (focus mk2) constant error messages like "System … More failure, Transmission malfuntion" and sometimes non start. Quick tap on dashboard and restarting the car worked for short time but got worse. Tapping the dash did help diagnose the problem...Paid for service, removed my IC and sent it to this company. Updates given from the moment the instrument cluster was received, called when IC was repaired and I received a final email with tracking for safe return. IC refitted and car has been working for a few weeks, problem solved! Highly recommend this company. Great customer service. 5* repair service

Flawless service. Normally when you contact a company for advice they either switch off or are vague at best. Not the case … More here, I had called for advice on a client's FIAT Ducato Motorhome, the technician was all too happy to help, talked through potential causes and solutions. I packaged off the vehicle ECU and had it back in under a week. Will 100% use you again and recommend to others. 10/10!

ECU were fantastic throughout and were able to clone my Ducato immobiliser into a 'doner' unit I sourced myself … More in Poland. The whole process took just a couple of days once they received the unit and they were able to test it with the key I provided. All in all a great service and value for money.

I was initially quoted £800 for a replacement ECU unit or £450 for a repair and fit. I was then referred to ECU Connection … More and given the owner’s contact details. To put it simply, they sorted out all my issues with ease. Thanks to their professional service, my wife is back on the road in the Merc, and life is so much better.
Great job, very professional, and a positive outcome all around. Thank you so much to the team at ECU Connection!

Used this company having come across them on YouTube (where they were fixing a car with the exact same issues ours was facing). … More My very basic home diagnostic machine wasn’t picking up the error codes, but a quick call to the company put my mind at ease that it was the airbag ecu causing the issue. They advised they would bench test it with their equipment, fix and return. My local garage was sceptical (they assume a new unit for £400-£600), but these guys and gals worked their magic and I reinstalled the original unit a week after being removed (thanks Fiat for making those bolts so easy to reach 😬).
The car immediately recognised the ecu brain, all errors had gone and the car is back to normal (I didn’t need to reprogram the ecu to the car luckily).
Would therefore recommend the company to anyone with this ecu airbag issue. Great service.
