About Us
We're CarsDiagnostic — a mobile car diagnostic service
It started simple. Too many people were paying over the odds at main dealers just to find out why a warning light was on. Others were getting vague answers from garages, replacing parts that didn't need replacing, and still ending up with the same problem.
We thought there had to be a better way.
So we invested in professional-grade diagnostic equipment, the same level of technology the main dealers use and brought it to your doorstep. Literally.
No workshop. No waiting room. No booking your car in for three days.
We come to your home, your workplace, or wherever your car is. We plug in, scan every system and tell you exactly what's going on in plain English.

Core Values
Here's what we believe:
Prioritizing Your Safety
You shouldn't have to pay £100+ just to find out what a warning light means. You shouldn't have to replace parts based on someone's best guess. And you definitely shouldn't have to take a day off work to sit in a garage waiting room.
We keep it simple.
We keep it honest. We tell you what's wrong, how serious it is, and what your options are. The decision is always yours — we're not here to sell you repairs, we're here to give you answers.
What we cover:
Our equipment supports 98% of all car makes and models on the road today — petrol and diesel, old and new. From a 2008 Ford Focus to a 2025 BMW, we've got it covered. And because we support the latest CAN-FD protocol, we can diagnose newer vehicles that most mobile mechanics simply can't.
Where we cover:
Based in Rustington and covering Worthing, Bognor Regis, Arundel, Rustington, Angmering, Ferring, Lancing, Shoreham, Chichester, Brighton, and everywhere in between. If you're not sure whether we reach your area, just ask. Chances are we do.
Same-day availability. Fair prices. Honest answers.
That's it. No gimmicks. Just good diagnostics, done properly, at your door.
