Can your car pass its mot with the engine management light on?
No, your car will not fail its MOT if your Engine Management Light remains on when the engine has been started if it is before June 2003 reg. Under the new MOT rules, it is classed as a major fail if your car is older than July 2003. If your light is on, you should have your car checked at a garage.
Is your engine management light on and your cars is due for a MOT? Well it may not be a fail! So many MOT stations wrongly fail cars because of EML is on.
What the DVSA MOT manual states is the following.
Engine malfunction indicator lamp (engine management light or ‘EML’)
Can your car pass its mot with the engine managment light on?
Turn on the ignition and check that the engine malfunction indicator lamp (MIL) illuminates and then goes off. On some vehicles it will be necessary to start the engine before the MIL goes off.
You need to inspect MIL fitted to:
- petrol vehicles with 4 or more wheels, not more than 8 passenger seats in addition to the driver’s seat and first used on or after 1 July 2003
- petrol vehicles with 4 or more wheels, more than 8 passenger seats in addition to the driver’s seat and first used on or after 1 July 2008
- gas and bi-fuel vehicles with 4 or more wheels, not more than 8 passenger seats in addition to the driver’s seat and first used on or after 1 July 2008
Kit cars, amateur built vehicles and American pickups are not required to be fitted with an engine MIL.
So next time a MOT station try’s to fail your cars MOT with an EML light on make sure it’s a correct fail.
What is an EML and how to fix it?
An EML light is just the cars way of telling you there is a fault. To fix your EML is quite simple, you need to firstly read what the fault code is on your car. It could be as simple as a plug or switch moved which has set a code on the car. This just needs to be reset or cleared to fix the EML problem.
