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

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!

Taken from a running vehicle and dry stored. - Good working order

The 'Unit supplied + cloning service (Exchange unit)' option is for the both the supply of a secondhand unit & the programming service (Cloning - Data transfer from your unit to this donor unit) To do this you will have to send us your old unit. Once we have received your old unit we will transfer the immobilizer data from your old ECU to this supplied unit & return you a replacement unit fully programmed to your vehicle. This unit will then plug straight in and work on your vehicle with your existing keys etc with no further programming necessary. Your vehicle mileage etc will be unaffected by this process & will still display your vehicles correct reading. You will not have to program keys / central locking keyfobs etc after installation. *In most cases we can extract the necessary data whether your original ECU is completely dead with 'No communication' with a diagnostic scanner*.
The 'Unit supplied only - No service required' option above is for the ECU to be supplied without the programming service included - You will be responsible for the programming yourself - Please only choose this option if you have access to necessary programming equipment & competent in its use.

1 . Scan the vehicle with a diagnostic scanner & record fault codes – rectify any faults recorded here first & check the wiring for faults

If your ECU has ‘No communication’

2 – If your ECU has ‘No communication’ with a diagnostic scanner it is essential that you check relevant fuses and consult a wiring diagram for your vehicle and verify the power supply & test the wiring to your ECU – particularly test power supply relays (Engine control relay). – ECU’s returned due to misdiagnosis are subject to a 20% restocking charge

If you are not a qualified auto electrician

If you are not a qualified / experienced auto electrician or garage technician and you are unsure if the problem with your car is the ECU then please consult one first before ordering – there is a 20% restocking charge for returns due to misdiagnosis

If your fault is a cylinder misfire

If your fault is a cylinder misfire please check spark plugs / leads / coil / injectors and wiring faults / headgasket faults etc before ordering, if these have been checked or replaced then it is important to check inlet manifolds for leaks, engine compression & perform a vacuum gauge test to check for valve problems.
