Bit old news really; if an MOT tester can see it's been tampered with(welding seams from being gutted) it'll fail. Been like that for a few years now.
Soot limits are relaxed and cars can be coaxed through, but it does catch out the worst offenders. So all they need to do is reduce the soot limit, then jobs a good'un
Report still fails to mention Nox limits not being tested. Which even brand new cars are exceeding (Renault being the latest offender).

The government could easily fix their vehicle pollution problems just by making stricter emissions tests at MOT time (petrol and diesel). No need for taxes, but that wouldn't earn them anything would it? 
Would also sort out these knackered 10yr old Arriva buses we get by us spewing out black smoke. As said before I know bus mechanics that have disabled the adBlu and start/stop systems on new buses due to reliability issues at request of middle management. Better emissions tests at MOT would stop all this lot in a heartbeat.

My 2010 Honda Civic 2.2 Diesel doesn't have a DPF ... which was one of the main reasons I bought it, well, that and the Scooby beating Torque of course!

The thing is some places cut the dpf open to clean them and re weld them although admittedly it's vot new welds on it its more likely that it's been gutted.
If only they'd put a clutch in the civic that could handle the torque. Got rid of mine due to endless problems including clutch, the final straw was when it started going rusty.

340Nm is quite impressive ... my old Scooby could only manage around 220? Something like that?

Bodgers. Simply no need to do that.
Maybe to replace the monolith, but companies that do this properly would cut and re weld on existing seams using laser or TIG, not MIG and usually replace the entire casing anyway.
And that's only needed if it's heavily clogged with ash due to using the wrong (cheap) oil or has melted through. If it's just soot accumulation, there are non-invasive ways to sort it, both on and off the car.

This is going to be very hard to be imposed . A lot of Dpf filters are up the back of the engine with very little access or visibility especially with engine guards below the cars

As said just drop soot ppm limit down to something sensible.... A healthy euro 5 diesel should register zero on an smoke/opacity test.
Fast pass is currently 1.5m-1 for a post 2008 car...a gutted DPF can "just about" slide under that. Set the MOT limit to 0.5m-1 for EURO 5 cars and those without a DPF will fail. Simples.

Found this: http://www.transportoffice.gov.uk/cr...20Research.pdf
It's dated 2005 and showed even back then they knew the MOT emissions test was lacking, and put forward proposals for stricter soot limits AND NOx testing.....yet 12 years on **** all has been done
