Focus mk3 st250 Ecu sent to first place Ecu testing com, who sent it back as could not do anything with it, called Ford they wanted 2k So looked again and sent here. 4 day turn around no messing installed and fixed no problems Fantastic service

My Fiat Ducato camper van was stuck in a field in Anglesey. Ecu was toast. Sent it to these guys. They cloned it to another ecu. Sent it back to me next day delivery. Plugged it in and worked perfectly. What a relief. Thanks guys. Excellent.

This time I purchased an RS4 ECU from far away Japan. This was my first time dealing with them, but the person in charge, Tom, was very kind and the delivery was very fast, which was a great help. I would definitely like to ask for your help in the future if I have any problems with ECUs. Thank you very much for this time.

A long standing mechanic I have used for the last five years recommended Colchester fuel Injectors to sort out my fuel pump issues, the team then found out it was the ECU, they advised me to go to Car tech as they had resolved similar issues with other vehicles, I did some research as the service wasn't cheap approx 25% more expensive, but the old saying is true you get what you pay for. They sorted out the issue . Brilliant service very professional.

It’s a great service you offer in a ever demanding industry. Thank you

Could not recommend more! Have used other ECU engineers before that have never fixed anything and just cost time and money. This company not only sorted our ECU problem but turned it over in 2 working days, not 4 months. Would not hesitate to send any further ECU's to these guys, they are an absolute gem!

Excellent service so far. We will pay any import duties as soon as we know what they are & where & who to pay them.

I ordered a cloned engine control unit for my Peugeot 1007 from CARTECH ELECTRONICS LTD, as no one in Germany likes to do anything with this type of control unit, SAGEM S2000. I initially had a few concerns as to whether everything would really work smoothly in terms of processing and I have to say that I was really positively surprised by all the employees of CARTECH ELECTRONICS LTD that I came into contact with. From my first inquiry to order creation, payment processing and shipping as well as feedback on completion, everything worked smoothly and smoothly. Big thanks to Tom, he answered all of my questions quickly and neatly via email. I can really recommend this company... Very good work guys, keep it up and thank you again best regards from Berlin

Fantastic service in all respects our vehicle had been off the road for 5 months. Fiat main dealer eventually told us it needed and Engine ECU £3500 fitted. But it was no longer available there for our £35k motorhome was written off. These guys fixed it in super quick time and got us out of a desperate situation. AMAZING

Great service and communication with these guys, old part collected and replaced then delivered extremely fast. We are in Australia and they were very helpful with all the issues that go with international service. Can’t believe how reliable they are. Received the part and plugged it in and my 6 month nightmare was fixed. Thank you car tech

I wish to commend and give credit to Cartech Electronics, Chris and all who had a hand in my issue over an ECU for a Q7. I could not have asked for nicer people who were helpful in my plight on getting my car back on the road. Chris and others, who I spoke to serveral times, were very respectful, professional, knowledgeable and helpful. I cannot fault their work ethic. Thank you so much for all the help so far. Hopefully the car will be back in my hands soon from Audi. Watch this space.

Recently purchased a VW Passat from a private seller & 1 month later the car wouldn’t start. Had an auto electrician have a look at the car and found it was a faulty ECU. Sent my ECU for testing which unfortunately came back as unrepairable due to severe water damage. There was no way of starting the car with the faulty ECU as it wouldn’t recognise my clutch was down whilst pushing in the key. Trying to find a replacement ECU with the exact same codes & spec was almost impossible. Came across this website and spoke with someone via WhatsApp who couldn’t be more helpful. Sent my ECU on the Tuesday and they sent the new cloned ECU back on the Friday! Car starts and runs perfectly now!!! Lifesavers. Cannot recommend this service enough. I’m self employed and not having my car meant I was having time off work and therefore losing money, so the fact this was processed so quickly has saved me money.

After being given the run around by my local Audi dealership in France and VW for 2 months, they told me I had to have a NEW ECU fitted by AUDI. Cartech electronics found an identical ECU and cloned it to my old one, which had been reprogrammed for ethanol and did it within a week.(ECU sent from France to UK, replaced, cloned, and delivered back to France) Great contact and service, I can't recommend them enough. 1100€ instead of 2400€ by Audi plus 690€ to reprogram again for ethanol. Thankyou, thankyou, thankyou :-D

This has been the best decision made, I was about to give up on the car as I was waiting for this part from the dealer for over a year! This company is Trusted, fast and reliable. He communicated every step of the way and had an amazing turn around time. Excellent work! I would recommend this company to any worldwide!

Amazing customer service.Really happy with the replacement ECU,works well.Verry helpful team and excellent work at highest level, admirations.Thank you

I am never one to leave reviews but after my Ecu being water damaged and having repaired by another company which did not work! I am over the moon my car is now running. These guys couldn’t be more helpful, answered all my questions and my new Ecu was sent quickly. Highly recommend!!

Megan, customer service, 2nd to none. Staff out the back, superb service. Let’s hope it sorts the problem, many thanks will update you asap

Spot on service and good follow up advice regarding clearing water drains to avoid the same issue. It was only once I removed the ECU cradle, it revealed blockages. Car now running well and thanks to the whole team.

We received outstanding service from start to finish, the ECU was sent back to us very quickly and cured the problem straight away. Would without doubt use Cartech again and would highly recommend them. Thank you everyone at Cartech!
