What Is a Diagnostic Check?
A diagnostic check is a detailed scan of your vehicle’s onboard computer systems. Modern cars are equipped with sensors and control units that monitor everything from engine performance to emissions and safety systems. When something goes wrong, these systems generate error codes — and our diagnostic tools allow us to read and interpret them.
This process helps us identify issues with:
- Engine and transmission
- Braking systems
- Airbags and safety features
- Electrical faults
- Fuel and exhaust systems
Once we’ve identified the fault, we’ll explain the issue clearly and provide a competitive quote for any necessary repairs. There’s no guesswork — just accurate, data-driven diagnostics from trusted professionals.
When Do You Need A Diagnostic Check in Birmingham?
You should book a diagnostic check if your vehicle shows warning lights, unusual behaviour, or reduced performance. Common signs include strange noises, poor fuel efficiency, difficulty starting, or issues with braking and steering.
Even minor problems can point to deeper faults, so early diagnostics can prevent costly repairs. It’s also wise to get a check after an MOT failure or before a long journey for peace of mind. At AFJ Limited, we use accurate fault-finding tools to save you time, money, and stress.
