Is an engine management light an MOT failure?
The engine management light is considered a major fault and will therefore result in your car failing its MOT if it remains illuminated. It's understandable, because if the light is illuminated then it's highly likely your car is either unsafe or nowhere near as efficient as it should be.
Put simply, the issue causing the EML to show needs rectifying before it goes in for an MOT, or it will fail.
How do I get rid of the engine management light?
Unfortunately, there is no quick or easy remedy for getting rid of the light if the problem has not been sorted on the car. If the light remains after the issue has been fixed, then we would recommend bringing your car into your nearest Evans Halshaw retailer who will be able to clear the code for you.
