Is an engine warning light an automatic MoT fail?
Is it an absolute fact that an engine warning light that stays on permanently once the car is up and running is an MOT fail? Is this cast in stone?

The engine warning light is major failure point on the MoT, but some older cars are exempt. The rule does not apply to diesels that were registered before 1 July 2008 and petrols that were registered before 1 July 2003.
