A warning light tells you something’s wrong, not what. Plugging in a code reader is the easy part. Working out why the fault is there is where experience counts, and we have one of the best diagnostic technicians on the Island.

Why a fault code isn’t the whole answer
A fault code points to a circuit or a sensor, but the sensor is often only reporting a problem that starts somewhere else. Replacing parts because of a code alone is how bills get big and faults come back.
We test the system, find the actual cause and only then recommend a repair.
Warning lights we can investigate
- Engine management (check engine) light
- ABS and traction control
- Airbag (SRS)
- Diesel particulate filter (DPF)
- Glow plug light on diesels
- Battery and charging
- Tyre pressure monitoring
Faults that come and go
Intermittent faults are the hardest to pin down. If yours only shows up on cold mornings, climbing a hill or after a long run, make a note of when it happens. The more you can tell us, the quicker we’ll find it.
If a light comes on while you’re driving
A red warning light means stop as soon as it’s safe to. An amber light means get it checked soon. A flashing engine light usually means a misfire, which can damage the catalytic converter, so ease off and get it looked at as soon as you can.
Common questions
Can I keep driving with the engine light on?
If it’s steady and the car drives normally, usually yes, but get it checked soon. If it’s flashing, or the car feels different, stop and ring us.
How much does a diagnostic check cost?
[CONFIRM: diagnostic charge, and whether it comes off the repair].
