What a Diagnostic Check Can Help Detect

Modern cars are fitted with onboard computers that monitor everything from emissions to engine performance. A diagnostic test can reveal:

• Engine warning lights and fault codes

• ABS or airbag system issues

• Sensor and ECU faults

• Electrical problems (e.g. battery, alternator, lighting)

• Transmission and gear-shifting issues

• Exhaust and emissions faults

• Poor fuel economy or reduced performance

• Problems that don’t trigger warning lights but still affect drivability

Many garages offer full-system scans or focused diagnostics depending on your symptoms, and you can easily compare these services through the Compare Repair platform. Simply enter your post code and select "Diagnostics" to reveal all of the garages near your location that can help with your vehicle issue.
