Modern vehicles rely heavily on sensors and electronic systems — so when something goes wrong, pinpointing the issue quickly and accurately is essential. At South Coast Mapping, we offer professional fault diagnostics using dealer-level tools, helping you avoid guesswork and unnecessary repairs.
Whether you’re dealing with dashboard warning lights, limp mode, rough running, or just want peace of mind, we’ll carry out a full diagnostic check and explain exactly what’s going on — clearly, honestly, and without the jargon.
We can scan and diagnose faults across all major systems, including:
Engine management
AdBlue and emissions systems
DPF and EGR faults
NOx and O2 sensors
Turbo boost issues
Fuel pressure and injector problems
ABS, traction control, and more
Our diagnostics are suitable for most makes and models, including cars, vans, and light commercial vehicles.
- Dealer-Level Equipment – We use high-end diagnostic tools that offer in-depth fault codes, live data, and system readings — just like the main dealers.
- Clear Explanations – We’ll explain the fault, what it means, and what your options are — in plain English.
- Mobile Service – We come to you across Chichester and the South Coast, so you don’t have to book into a garage or waste time off the road.
- Quick Turnaround – Most diagnostic checks take 30–60 minutes, with instant results and a breakdown of the next steps.
Honest Advice, No Guesswork
We don’t believe in throwing parts at a problem. Our goal is to get to the root of the issue and give you a clear path forward — whether that’s a software fix, further repair, or simply resetting the system after a resolved fault.
