Yes.
But it's a visual test. If the car was manufactured with a DPF it has to be fitted with one at MOT time.
There is no way (yet) for a car to be tested emission wise if it has a DPF fitted.
Same for the CAT as well now on dervs. Visual check only. As dervs can pass emissions without a CAT or DPF.
