Compare Nissan engine management light repair quotes from specialist garages

The engine management light (EML) - also referred to as the check engine light - is a small engine symbol that becomes illuminated on your dashboard to indicate a problem, the severity of which is suggested by the colour of the light (red or yellow) and whether it stays on or flashes (usually due to misfires).

Many things can trigger the EML. Some are easy to fix, such as a loose fuel cap, while others are more expensive, such as a faulty catalytic converter. One of the most common reasons is a defective oxygen sensor - if your car is also experiencing a drop in fuel efficiency and black smoke from the exhaust, this is likely why.

Read this guide for more information about why the engine management light comes on and how to fix it.

You don't have to risk driving your car to a garage when the EML is illuminated. Instead, you can book a mobile mechanic, who will carry out an engine management light repair at a convenient location for you.
