New MOT changes besides dpf/cat

[Kezzieboy]

DPF is fitted to new diesel cars, mandatory after 2009 when euro 5 standards came along.

If the car has had a dpf fitted new and manufactured before September 2009, it will only be designed to euro 4 emissions then you could potentially rule bend there if someone had removed a dpf. since DPF wasn't mandatory on euro 4 cars.

I guess this is going to become one of those "famous" grey areas nobody really knows about

No, it says where a diesel car had a CAT or DPF fitted as standard, it must be present. It's not just DPFs, so you're still f*cked
