Mobile Car Diagnostics & Fault Finding in Dorking
Any garage can read a fault code. Finding what’s actually causing it takes proper equipment and experience — which is exactly what we bring to your door across Dorking.
Diagnostics that find the cause, not just the code
As a market town, Dorking generates a steady stream of work for us, and the A24 on the doorstep keeps travel times short. Same-day visits are often realistic — just ask when you call.
A fault code is a clue, not an answer. “O2 sensor” on the reader might mean a dead sensor — or a wiring fault, a vacuum leak or a failing part upstream that’s dragging the reading down. Replace the sensor and the light comes straight back, and you’re out of pocket. Proper diagnostics find the actual cause.
We use dealer-level equipment to read live data across every system, test components and trace wiring, so we can tell you what’s really wrong and what it’ll take to fix it — before you spend a penny on parts.
It’s a mobile service: we come to you anywhere from the centre to the RH4 outskirts in Dorking, and most faults are pinpointed within the hour.
MOT emissions failure, a rough idle, a mystery battery drain — if the car’s behaving oddly, live data usually tells the story quickly.
Need something else while we’re there? We also cover immobiliser & module repair, ECU cloning and instrument cluster repair for Dorking drivers.

Car Diagnostics in Dorking — your questions answered
Can you fix it there and then?
Sometimes — minor faults we can often put right on the spot. For bigger jobs you get a clear diagnosis and an honest fixed quote so you can decide how to proceed.
My warning light is on — can you find out why?
Yes. We read the fault codes as a starting point, then use live data and component testing to work out what’s actually causing the light — which is often not the part the code first points at. You get a clear answer, not a guess.
Can you check a car before I buy it?
Yes — a pre-purchase diagnostic scan is a smart move, flagging stored faults and issues that aren’t obvious on a test drive before you hand over any money.
Which makes do you cover?
The vast majority of makes on UK roads. Tell us the make, model and symptoms and we’ll confirm before we set off.
Do you cover all of Dorking?
Yes — we cover every part of Dorking and the surrounding villages, including all RH4 and RH5 addresses. We’re fully mobile, so we come to your home or workplace at a time that suits.
