If your engine management light (EML) has come on, you might be wondering whether you can keep driving, what’s causing it, and if it means your car will fail its MOT.
This article will take a look at what the engine management light means. In particular the common causes and what you should do next if that light comes on.
What is the engine management light?
The EML - sometimes called the check engine light or engine warning light - is a dashboard symbol that looks like the outline of an engine.
It’s controlled by your car’s engine control unit (ECU), which uses sensors to monitor performance and emissions. If a fault is detected, the ECU switches the light on.
