Excellent service from ECU connection. They took on what was thought to be a simple ECU repair for us. As it turns out it … More was far from simple due to the Air bag Ecu from the Alfa being a very rare unit/part number. They carried out the required research into the unit, repaired it and though this was a lot more work from them the repair was carried out at the original quoted price. We at Brunel Motors woulkd defineely use them again.
Great job Guys, thank you.

I required a replacement ecu for a Suzuki Swift which these guys could sort out for very reasonable money. First attempt … More failed to reprogram the key fob codes but all good on return. Cost me a few extra days but proved this job can be carried out by them successfully and cheaper than a new part too. I would fully recommend these guys and give them a go.

Great service! Justin and the team always there for questions and fantastic knowledge!
Now my go to shop for any issues. … More
I had my Mercedes A200 air bag ECU cloned after the original ECU was giving out random faults.
I needed the VIN to be transferred to the donor
ECU after coding, dealer level coding.
ECUs were returned with a full report.
After reinstalling the donor ECU fault codes were cleared and I didn’t have a problem with the VIN number fault.
Mercedes dealer wanted double the cost if not more with coding for the replacement ECU and were not particularly helpful with any of my questions.
Thanks again team!

I would highly recommend this company, They are absolutely First Class.
The work they did on the ECU was excellent.
I also … More had another issue with my vehicle which they offered me some further options.
The technicians and all other staff were brilliant.
I have fixed the other issue now and with the ECU it is running the best it has done in a very long time.
So my wife's 2003 little clio with over 155000 miles on the clock, i think will go on for another few years yet.
Thank you once again ECU Connection for your work and guidance.
I have already recommended you to a couple of friends and will continue to do so.
Regards,
Geoff.

Very happy with the refurbishment of my instrument cluster. Great communication and reasonable prices, all done within the … More timescale stated. Seeing the process on YouTube was really helpful and persuaded me to send the cluster in for refurbishment, rather than attempt a repair myself. It's great to have my car back to normal.

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

Important! – Please read! - It is essential before ordering an item that the part number of the item you are ordering matches the part number EXACTLY of the component on your car that you need to replace. Also ensure that the fault with your car is an ECU fault and your problem has not been misdiagnosed. We strongly recommend having your car diagnosed by a competent Auto-electrician or specialist garage before ordering. If we supply a faulty ECU we are happy to provide a replacement or fully refund you if a replacement is unavailable, however if your existing problem persists with your car then the fault has most probably been misdiagnosed – if you request a refund on this basis then a 20% restocking fee will be deducted from your refund & return postage will be at purchasers expense.
