Our Mobile Diagnostic Check
Modern vehicles are packed with sensors and onboard systems that monitor performance, safety, and emissions. When something goes wrong, your car’s computer stores fault codes that help identify the issue.
Our mobile diagnostic check includes:
- Full scan of your vehicle’s onboard systems
- Identification of fault codes and system errors
- Interpretation of warning lights and dashboard alerts
- Inspection of engine, transmission, ABS, and airbag systems
- Advice on next steps and recommended repairs
- Optional reset of service lights (where applicable)
We use professional-grade diagnostic tools to access your vehicle’s data and pinpoint the cause of any issues, saving you time, money, and guesswork.
When Should You Book a Diagnostic Check?
A diagnostic inspection is ideal if:
- A warning light has appeared on your dashboard
- Your car is struggling to start or running roughly
- You’ve noticed unusual noises, smells, or vibrations
- Your fuel economy has dropped suddenly
- You want peace of mind before a long journey
- You’re buying a used car and want to check for hidden faults
We come to you and carry out the inspection on-site, so there’s no need to visit a garage or wait for an appointment.
