I contacted Cartech with a view to replace the Ecu on my SLK which had been proved faulty by my auto-electrician. They provided an excellent service supplying me with a replacement secondhand ecu which was reprogrammed by their technical dept. to suit my car, all within a matter of days. All I had to do was to send my ecu to them so that they could carry out the reprogramming. Their office was extreemly helpful, answered my queries and advised me of progress. I have highly recommended them to my auto-electrician who have several branches and my local garage. I am sure that both will use them in the future. Thank you Cartech Electronics.

First class, thanks 👍

Just had to say how fast and efficient the service was I phoned on tues 5th Dec pm sent my unit next day service that afternoon Received replacement unit on Thurs 7th Dec am. Very much appreciated

Tusen takk for rask og rimelig service. Sendte ECU for kloning,og fikk en fungerende tilbake. Plug and play. Supert!! 😀😀

I was hesitant to purchase an ECU from them as my previous ECU purchases have had issues but with CARTECHELECTRONICS those doubts were put to rest. The ECU was plug & play and I am very please with the very fast delivery. I would definately recommend anyone look for a great affordable ECU to purchase from this company.

ECU Decoded and returned within two days. //Outstanding// turn around time. Would have no issue using again and have already recommended to a friend. Very happy.
