Cartech Electronics Ltd Reviews 

The cloning of this unit to my own solved a problem that the main dealer could not solve.
I tried other companies, but Cartech came up trumps, thank you and saved me a fortune on a new unit if you can get one.

I was told by a local company that the ECU in my BMW was beyond repair, I googled a replacement part and ended up talking to Tom from Cartech.. he explained the whole process and would answer emails within 10-20 minutes every time, the ruined ECU is now cloned and back in the car. Absolutely brilliant service

Excellent service and product. It worked perfectly so we are delighted, indeed after having been given the run around by Stellantis for months we wish we had found you much sooner.

Excellent service every step of the way. Started with a question through their contact page and expected the usual "thanks for your question"-response, but was pleasantly surprised with a very fast answer and great help. I had to send my "old" ecu to be cloned and since I live in the Netherlands, that's not just going to the post office. But they helped me all the way. It got picked up at my house without issue.
The service didn't stop there. They kept me informed every step of the way, answered every question really fast and really helped. They made an otherwise bad experience (car broke down) a whole lot better!!! Thank you again and a true recommendation.

ECU fault on a Fiat Ducato 2.3 motorhome that Fiat Commercial could not fix! - Daniel and team advised they could. Posted it to them on a Saturday and got it back the following Wednesday, even though I live in Northern Ireland. Absolutely fantastic service. Put it back in and drove away with no faults or lights on the dash. Thanks Guys - much appreciated.

Fantastic Company! Super quick and great communications! Recommended if you have ECU problem and want your car back on the road within a week!

Old ECU sent on Friday 19. 12. Received by Cartech on Monday 22. 12. Processed and returned to me on 23. 12 and received on morning of 24. 12. Fitted to the car and it's been fine since. First class service, considering the time of year and how busy things often are at Christmas/ New Year.

ECU Repaired
Excellent all round service. Highly recommended. The damaged ECU was repaired and the car is back on the road.

They supplied a cloned replacement, quickly and very reasonably priced, recoded and plugged it in and instantly job done !
They keep you informed every step of the way.

I am writing this review from the USA. My Dodge/Mercedes Benz 3.0L, V6 Diesel, sold actually as an RV in the USA, a Winnebago Product, developed a short in the ECU. The OEM is Bosch for the MB, but unfortunately this part has been discontinued. Bosch will only repair via authorized Bosch Service Centers, NIL in the USA, and lacking coordination, leaving me in a real lurch. I researched throughout the USA, made multiple contacts, researched and read review, contacted MB and Bosch directly, before locating Cartech. Fortunately, for me, and YOU, Cartech offered a turn-key option, pick up, clone, and delivery of an ECU, plug and play ready, at the best price on the internet, not to mention having the BEST reviews. I found many comparable services, much more expensive, and not rated very well. From my first contact with "Tom" I was literally assisted throughout the entire process. What a great company, people, and service. I am writing and sharing this with others, who may find a need for similar services, at a great price with some assurances of services, especially those, like me, located outside the UK.

Very good service and excellent communication. BMW had a faulty ECU after cloning the ECU the car runs smooth again! Many thanks Daniel for the great and helpful communication!

Good Job!!
Very helpful over the phone, as we've not used them before. Really quick turn around. Highly recommend these people again.
Thanks

Porsche ECU

Great service, all faults rectified, thank you!

Having spent nearly a year replacing different components on minibus to no avail with different fault code readings leading me up different paths I done some more testing to find some component signal wires had voltage in them so that would lead me to believe Ecu was back feeding so took the plunge and found CARTECH electronics had a plug and play Ecu ready to clone my one to also there is a option to try before you buy fully for a small fee to test if your Ecu is really at fault brilliant idea!! So from start to finish the whole experience was amazing from them sending courier to cloning and sending back was great have taken long to review as can’t believe I have a fully working minibus with no codes and dash lights four weeks later top work people and many thanks

To Tom and Daniel, as you would be aware i am from the Caribbean and it always good to commend people when they do a good job, although my ECU was trash the effort and time Daniel put into this was unbelievable, i thank you guys for the honesty and communication, for me everything was easy all i had to do was just go the DHL and rest was history with the experience i had i will always recommend Cartech Electronics, thank again kelvin

First class service. Speedy & hassle free delivery of a product that works.

Absolutely spot-on, these guys. Super-skilled, speedy, fair. Got me out of a really bad situation.

The team took my old flooded unit and cloned it to a refurbished item. Turn around was very fast and the unit looked brand new where it had been coated to look nice and clean. Started the car straight away no issues at all

I was very pleased indeed. The van has never run better & the cutting out has stopped. As good as their word all settings copied to the new ecu & started first go. The ecu supplied gave the appearance of being spanking new & I don’t know how they do it in the price. They got the old one Thursday & the new one was on the way back to me Friday ( on a next day delivery).

Excellent Service
New ECU arrived very quickly and resolved the issues with the car - Thanks for your prompt service
