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.

Removed from running vehicle and dry stored - Good working order

This ECU is supplied 'Virginized' (Reset to an 'As new' / Virgin) state and will self code to your immobilizer system when it is plugged in with no further programming of keys etc necessary. Your vehicle mileage will be unaffected & display as it should. Your central locking will still work on your remote controls etc. Full installation instructions included.. If for any reason it will not self code you can send it back with your original unit for bench programming (Data transfer) at no extra cost!
We also offer a separate 'Virginizing service' for this type of ECU - For example if you have already sourced a replacement unit for your vehicle & are looking for a way to program it to your vehicle then we have the solution!

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.
