Engine management light - MOT Failure?

[j4ck100]

My Volvo V50 T5 has an intermittent engine management light, can't find a straight answer on the web as to whether this is now an MOT fail due to new regulations as it is being tested tomorrow! Can anyone advise as to this ?

Cheers

Don't think the light would be a failure as it's not a safety system like abs/srs etc. However, it could mean that your emissions test will fail, as a dodgy oxygen/lambda sensor is a common cause of the engine fault light coming on, showing that the car is running too rich or too lean. Car could also be in "limp" mode.

Not testable so the light being lit is not a fail, as above other problems causing the lamp to light may lead to a fail.
