Welcome to 125 Coding – West Yorkshire's Car Coding Specialists

At 125 Coding, we're passionate about unlocking the full potential of your vehicle. Based in Dewsbury, West Yorkshire, we provide expert car coding, programming, retrofits, and diagnostics for a wide range of makes and models — from VW and Audi to BMW, Mercedes, Porsche, and more.

Whether you're looking to add Apple CarPlay to your Golf, fit a Front and Rear Dash Camera to your Brand New Audi, retrofit a Reverse Camera to your BMW, secure your Range Rover or get a full diagnostic scan on your Ford, our team has the tools, training, and experience to get the job done properly.

 

What We Do?

Car Coding & Programming Unlock hidden features, activate factory-fitted options, and personalise your driving experience. Unlike generic garage tools, we use the exact same dealer-level diagnostic systems that main dealerships use — so you get the same quality results, without the main dealer price.

Apple CarPlay & Android Auto Retrofits - Bring your infotainment system into the modern age. We retrofit Apple CarPlay and Android Auto to vehicles that didn't come with it from the factory, giving you seamless smartphone integration at a fraction of dealership costs.

Reverse Cameras & Dash Cameras - Improve your safety and awareness on the road. We supply and fit reverse cameras and dash cameras with a clean, factory-finish installation — no messy wires, no cheap brackets.

Diagnostics & ADAS Calibration - From fault code reading to advanced driver assistance system (ADAS) calibration, we have the specialist equipment to diagnose and resolve issues quickly and accurately.
