Want to say what it was?

some emission sensor or other

the actual emissions were fine, it was just the sensor that was
buggerd

Pattern ones are about £30.


You shouldn't tell him that he likes to think the EU caused him to
scrap
the car and not stupidity.

Oddly, it was the US that started emissions controls on cars, not the
EU.
Nothing to do with saving the planet, but to make things more
comfortable
around LA.

And an MOT doesn't check emissions throughout an engine's range.

but it does check that the sensor warning light is off


Any condition I can think of that would cause the engine management light
to come on would also result in a failure;

MOT Failure or Engine Management failure?

but I don't think that just having the light come on would, by itself, do
so.

Any mandatory waning light that is permanently on, is an MOT failure. The
owner is expected to fix, whatever it is that has caused the light to come
on.

The excuse "I don't use the rear seats so the seat belt warning light wrong
being on when no-one is sitting in the rear seats isn't a problem for me",
doesn't wash.

(and any warning light that doesn't come on at start up is also a failure -
to avoid people just taking the bulb out, if that's even possible with
integrate consoles)

Although I'd be interested to hear of any possible examples where it might
not.

The engine management systems light comes on when it detects any of the
sensors has failed. It matters not that the emission are still 100%
correct. The failed sensor is enough
