What you might be seeing
- Amber engine symbol steady — car may drive normally
- Flashing engine symbol — usually with shaking or power loss
- Light with reduced power ("limp mode")
The likely causes, honestly ranked
- Emissions sensors (lambda/oxygen), EGR and air leaks
- Ignition: coils and plugs misfiring
- DPF issues on diesels driven mostly in town
- Loose fuel cap — genuinely, sometimes
Do this now
- Steady light: book a diagnostic read locally within days, note any symptoms
- Flashing light: pull over safely, stop the engine, request help at the car — continued driving can destroy the catalytic converter
- Note what happened when it lit: cold morning, hard acceleration, after fuelling
What to avoid
- Clearing the code without recording it
- Driving weeks "waiting to see" — small faults grow expensive
- Guessing parts from an internet code lookup — the code names a symptom, not always the culprit

Frequently asked questions
Can I drive with the engine light on?
Steady amber with the car running normally: drive gently and get it read soon. Flashing, or with power loss, smells or noises: stop and get help where you are.
Will an engine light fail the NCT?
Yes — a lit malfunction indicator is checked. Fix the cause before the test rather than hoping.
How much does a diagnostic check cost?
The read itself is quick; the value is the interpretation. Local garages and mobile mechanics quote the diagnostic and then the actual fix separately — get the read before authorising parts.
Why did the light come on after fuelling?
A loose or worn filler cap can trip an evaporative-system code. Tighten it properly; if the light stays on across drives, get the code read.
