Petrol Particle Filter

Is it visible and identifiable? If so, it’s tested.

We only need to check components that are visible and identifiable, however, its unlikely that an emissions test would pass without the component fitted.

As with all emissions equipment, if you know it should be there and it isn’t then you fail it. If you’re not sure, it’s given the benefit of the doubt and passed.

If it passes a emission mot standards test good to go

I would of thought that because the discription of the component contains the word particulate filter ,being petrol or diesel is irrelevant,particulate filters are part of the emissions control system/exhaust system therefore its testable item .

Highly unlikely you'd see this part removed,there's no reason for it ,GPF don't give anything like the grief DPF cause .

Regarding ‘performance’ I’m pretty sure the presence of the PPF will at least have some effect on hydrocarbons and therefore CO, which are tested on the emissions test.

There is documentation on looking for all emissions control equipment. The question is, will the tester know if it was fitted as standard. There will usually be some clues.

Reading between the lines, it seems like you’re trying to remove one/get away with one that’s been removed - if you are a tester, be careful.

I’ve been envolved with custom exhaust fabrication for 25 years, we used to do shed loads of decats and DPFs, mostly for performance or noise purposes. DVSA sent a circular stating anyone that conducts that type of work whilst also associated with running a VTS will have their authority removed, we stopped removing emissions equipment overnight.

Some of the other businesses in the franchise didn’t and were stopped from testing even where there was only a tenuous link. I.e. a guy that was sending cars to his cousins garage for such works lost his authorisation to test.

dwain is right GPF s influence the hydro carbon s ,carbon monoxide and nox .

These filters from what I've noted are fitted very close to the manifold /turbo and would be obvious to see if one one missing ,these system are still fitted with cat converters so you'll always see or should see both .
Manufacturers did have a date that GPF had to be fitted mandatory but I ain't sure.

If I didn't know it had one and there was no visible signs of tampering of a emmisions related item what can you  do ? There is a interesting article on garage wire magazine on this where DVSA  has prosecuted a tuning company   for removing emissions related items and fitting pop pop bang bang mapping software on this the other day and rightly so
