Why choose North West Car Coding

We Fix What Others Can't

Many customers come to us after other garages and main dealers couldn't fix the problem. We trace the real cause with the same software the dealers use (Xentry, ODIS, ISTA and IDS), then fix it.

Fixed Online, Anywhere in the UK

Coding and diagnostics can be done remotely across the brands we cover, without leaving home. We connect to your laptop and do the work in a live session. Prefer to visit? Our Manchester workshop does same-day appointments.

Fair Prices, Quoted Upfront

Send your reg and what you need, and we'll give you a straight price. Customers tell us our prices are very competitive, and the work is usually cheaper than a main dealer's.

“Credit where credit is due. This is your man for coding! All done remotely with VNCI!! A few days ago I had an RS3 8Y that was on its ass that no one and I mean NO ONE could code. The original ECU was cooked after the jump leads touched together. I sent the ECU off to a "specialist" who removed the tricore CPU to put into a good ECU so it would hold the coding but he bust 1 of the pins which was in use. I had no ECU practically, to go off and another ECU I ordered online from another car made it a complete gamble as the security on these is tighter than Fort Knox. We had major coding issues and it took a few days and even sent out tickets to ODIS but to no avail did we achieve long coding success. Today, he managed to code the ECU and the car runs and drives perfect with no issues. A huge relief! I had many people come out, they'd promise me the world and could not succeed. Although this took a few days the main thing is it got done and it runs. He could have left it like everyone else scratching their heads but he didn't and for that I rate him 5 stars. Prices are 110% fair — didn't charge me anything extra or any hidden costs, legend!”

“Excellent service and after sales experience. I made initial contact by WhatsApp as I'd messaged so many independents to get a spare key programmed to my E Class only to be told it was dealer only time and time again. Northwest Car Coding Ltd was able to source and program in a genuine spare key and the lead time was much quicker than my local dealer was quoting. I would much rather use a local independent company where I can than pay a national dealer. I made 2 visits to them in Manchester and the key worked to open and start the car. My car did skip a step at the initialisation stage for the new key which put it into limp mode when using the new key but not the original so after messaging Northwest Car Coding he was very helpful and talked me through how to resolve the issue in 10 minutes. If I ever buy another Mercedes with only 1 key I know where I will be going for a spare without a doubt. Definitely support a local independent business over a national dealer.”

“Absolutely spot on. Had a GLE Merc three dealers and two independents wouldn't look at. Two hours with this man online and it was perfect. Top class service at very reasonable money.”
