Cartech Electronics Ltd Reviews 

Excellent
Very fast response and great product knowledge

Fantastic customer service, really fast delivery and the ECU worked perfectly. I very highly recommend this company.

Amazingly FAST Delivery!

Delivery uber fast, and the ECU units I ordered at two different times have been working great as expected and to my absolute satisfaction.

ECU 2010 AUDI S5
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 they 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

I own a TD5 defender and needed an ECU to rectify a problem. After shopping around the price was the best quote I had had. I sent the ECU to Cartech and they diagnosed the problem and cloned my ECU saving all my remap and EGR delete. This was invaluable. They kept me informed at all stages. All in all it took 2 days from sending the ECU to receiving it back and fitted to the defender and having it running again. Exemplary service, I highly recommend them.

Had problems with my van, suspected this to be the ECU. Sent mine to Cartech who cloned onto replacement ECU and returned. Unfortunately this didn't resolve the problem, it did however rule out the ECU as the fault. There was no messing about with the refund which landed back in my account in a few days. Communication was great.

Brilliant - no other word for it. My BMW F650GS cut out on me on a short Thursday ride. Dreaded 'EWS' on screen; immobiliser active. Friday spent checking wiring and trying to communicate via GS911. Eventually googled the ECU code and Cartech site came up. Sent off old ECU on Saturday. By Wednesday, the cloned ECU arrived. All faults now cleared and fired up straight away.

Happy Down Under
Very happy, Defender off the road for a month, contacted Caretech from Australia, received ecu and back on the road within a week.

The ECU on my 2014 Passat had water ingress and one of the many pins had broken.My local garage gave me some contacts to see if it could be cloned, also saying dont go to VW as it would cost a fortune. Got in contact with Daniel at Cartech who said post it to us and we will do our best. And boy did they do their best, alway good to communicate with and got it back in a couple of days, pluged it in and away to go. Thank you for your service. Great firm.

Brilliant service, I was quoted £2600 from volkswagen after my ECU gave up, they were charging £1500 for the part alone. I took the ECU out myself and gave it to a local garage who advised me they couldn’t talk to it it was dead and couldn’t be cloned. I called Cartech who told me to send it to them and if they couldn’t do it they would just post it back. Within 2 days of sending it they called me to say it was all cloned over and ready for posting next day delivery, they sent me a link and I made the payment of £360 and received the ECU a couple days later as it was the weekend. Plugged it into the car and it all worked perfectly, saved me £2240 in total!

I was searching the internet high and low to find someone who could fix a ECU on a BMW E60. Come across this company and wow amazing. From paying for the order the ecu was collected within an hour and then fixed and sent back to me all in 3 days.

All done via what's app and the communication was second to none.

ECU had gone on my Business vehicle (Ford Connect) no one could help me locally. Spoke to Tom got a replacement within a week and now sorted. Cannot thank you enough.

Tried for ages to obtain ECU for customers car. Cartech came up on google search. The service was second to none. I sent our customers ECU off and the replacement was delivered back within 5 days. Absolutely faultless. As all data was swapped from our ECU to the new one, It was a plug & play so no issues with recoding. One very happy customer who had their car back far sooner than expected and for a far cheaper price than for replacing the ECU. I've no hesitation in recommending Cartech, or using them again in the future

From the time I contacted Cartech, the communication was good and advice given. The turnaround to repair/ replace the ECU was great. I think the price was excellent compared to buying a brand new unit from Ford. Well done.

The engineer working on my car sent me a link to the Cartech website so that I could order the replacement ECU for my Zafira. Cartech were easy to deal with, the ECU was well packaged and arrived fairly quickly.
My car is now back on the road and running fine, thanks to the replacement ECU.

Excellent service. Ecu bk 2 days car started first click

ECU Clone, Saab TTiD.
Sent my water-damaged/corroded ECU-box for cloning, took less than a week incl. transport from Sweden and back. Super service, quick response, good price and great product! Worked perfectly :)
Thanks! /Kristoffer

I was looking for a plug and play option to replace my struggling ECM. I ordered the shipping service and clone service and it was so easy and fast consider I was shipping from Canada.
