If your engine management light (EML) has come on, it’s your car’s way of telling you something isn’t quite right. At Dom’s Garage Services in Letchworth, we use advanced diagnostics to identify the cause quickly and get you safely back on the road.
What Is the Engine Management Light?
Also known as the check engine light, this warning symbol looks like a small engine and can appear on your dashboard in orange or amber. It’s triggered by your car’s ECU (Engine Control Unit) when it detects an issue with the engine, emissions, or other systems.
Should I Worry If It’s On?
If the light is steady: You can usually continue driving, but it’s important to get the issue checked soon to prevent further damage or increased emissions.
If the light is flashing: This usually indicates a more serious issue such as an engine misfire. You should stop driving and seek assistance immediately to avoid engine damage.
Common Reasons the Engine Light Comes On
- Oxygen (O2) sensor fault
- Loose or damaged fuel cap
- Faulty spark plugs or ignition coils
- Catalytic converter problems
- Mass airflow sensor issues

Can I Reset the Engine Light Myself?
While some code readers can clear the light, this doesn’t fix the problem. If the root cause hasn’t been addressed, the light will come back on. We recommend having the system properly diagnosed to avoid future breakdowns.
