- - DPF Trap 4.2TDi (https://forum.a8parts.co.uk/showthread.php?t=6870)

When I looked into this, I concluded...
There is no law specifying a DPF from new, so no law about removing them.

European emission standards define the acceptable limits for exhaust emissions of vehicles sold as NEW in EU member states, which most (but not every) manufacturer chooses to include DPF's in order to comly with.

Once the vehicle is in service, it does not necessarily (explicitly) have to comply with these regimes in the UK, but has to pass the MOT smoke test as defined in In-Service Exhaust Emission Standards for Road Vehicles manual, which differs for each vehicle variant.

Both diesel and gasoline cars both have MOT test procedures which differ from the methodology of the EU test.

With gasoline cars' MOT's, a crude emission test is carried out which specifies a typical HC limit of 200PPM, but the EU tests don't even specify a limit until EU5, and we can have 5x the CO in the MOT test than >EU3 standard.

Hybrid vehciles don't even have MOT emissions test, even though they may have a defective conventional engine.

Once deleted tho would you (legally) have to get the car reclassed tax wise as it must be a heavier pollutant or is it not, as it's done on CO2 and the DPF removes the bits that kill my kids?

Given the quite literally 100's and 100's of miles between you two, I'm thinking if his fumes are affecting your kids, then theres a pretty big problem..... ;)

Answered +++

And yeah IT there are a few trees between us, the kids should be fine :)

Dunno.. I've had some bad curry after effects in the past :)

Though it's the lumpy bits, not the gas that's the issue... should be OK...

:ROFL: That's what they mean by heavy particulates

Wee update... Car is back from BroTek with DPFs removed, and Horses (Stage 1) installed.

- DPF was pretty fooked despite mostly motorway miles but apparently 100k is getting on for the expected life!

- Horses... Noticeably different car I'd say.. much smoother through the range, and three figures on the dash is reached rather quickly. And managed to light up the Traction Control light even after switching to second in the dry :) Just need to find myself a dyno somewhere I think.

Doesn't sound too different as all the silencers and cats are still in place.

The DPF shares a can with the second cat, so they need to be careful taking it out. Will get a chance to have a good blast tomorrow as I've only been out in busy traffic today.
