De-catting and new MOT rules

[Toms306]

But NOx is almost impossible to measure reliably...

NOx is a sign of a HEALTHY engine, if you catch my point, the fact it produces NOx is a GOOD thing as far as the engine is concerned, it means the combustion temperatures are good and you won't get much unburnt/part burnt HC, it's just that the earth doesn't like it so much!

I can't see a way they're going to measure if the NOx output is too high on an engine any time soon...

Yeah I see what you mean, and the earths f*cked anyway...our parents generation ruined it so not much point worrying about it now!
