Talking to an MOT tester yesterday, he said the new emissions test for diesels will only apply to new vehicles.
Illuminated warning lights that remain on, i.e. engine management light etc, would be a fail. There is a reason that light keeps coming on.
Interesting...........
The BBC news presenter and MoT tester made the point relating to older diesel cars with a DPF (an example of around 8yrs was used), that if smoke can be seen from the exhaust it is a major fault.
The document (linked below) details the Gov position, saying vehicles with DPF will be tested to “the manufacturers plate value (when present), or a new lower limit for newer vehicles”
