DPF crackdown and EGR delete
Discussion
Given the current publicity around a crackdown on DPF removal and, presumably a heightened emissions test for Diesels as part of the MOT, where would one stand on EGR removal?
My diesel is Pre-DPF (2007) and realistically we will be keeping it for the next three years. I had intended this year to carry out an EGR delete as part of a thorough over-hall/service to keep things running nicely for the next few years and limit surprise bills, however, given the lack of a DPF already, will the removal of the EGR impact sufficiently on emissions to render the vehicle a fail on the MOT. The vehicle is currently re-mapped to 185BHP, so is conservative with power and doesn't smoke noticeably, though i expect this impact emissions as well?
Any thoughts?

No. The 'crackdown' is complete vapourware. As of right now if you have a dpf from the factory, then there is a visual inspection to ensure that it appears to still be there and a BASIC test of smog. If you don't have a DPF all you get is a VERY basic test of smog. If your vehicle has passed MOTs up until this point then you will be fine.
Any future 'crackdowns' on DPF removal will only affect new vehicles, tightening standards for older vehicles retroactively has never before been done and is a literal minefield to properly implement.

This annoys me greatly old s
tty buses and Taxis. But things are slowly changing - in Reading I'm seeing far more Prius Taxis and many Taxis have stop start but the buses a number are hydrogen they make a whirring noise unusual better than a bus diesel noise and zero emissions
What I don't get is why don't they make electric buses? Surely they can make them do 200mile range ideal for non stop bus routes in a town all day long.
Why not allow electric vehicles use the usually empty bus lanes passing all those vehicles with crushed Dino fuelling them that would piss me off and possibly encourage me to get an EV

Surely it's more important to keep the polluting cars moving, so they're polluting for less time? Let them use the bus lanes, whilst the zero emission cars can sit in traffic.
No not at all yougive crushed Dino users the encouragement they need and if it's frustrating them out of cars then so be it. Thanks, I thought that might be the case but it's good to get the opinions of people that know stuff. Fwiw I'd like my next car to be electric or hybrid, if only they didn't all look like a child had drawn a "car of the future". Vauxhall ampera wasn't bad looking but they don't seem to make it anymore!

EGR "delete"? Don't you mean EGR "removal"? Delete is such a stupid term. Oh look at me, I deleted my EGR, I deleted my spoiler etc. etc. No you damn well didn't, you just removed it.
Not so sure BMW offer model description delete as a free optional extra. So he is playing by OEM terminology.

No the egr is not removed it's blanked off and then mapped out the Ecu software hence the word "delete"Unlikely - the costs alone of tooling up every test station for measuring evidence of egr removal (nos emissions presumably - it would need to be accurate and well calibrated in any case). Particulate testing would be just as costly and prohibitive - so aside from the usual visual/optical tests they do now - I think it very unlikely.
On an aside, I would take any panicked news story about banning this or that or new testing procedures with a massive heap of sodium chloride. These things are always talked about - like many things it sounds like a really nice idea in theory but in practice it's less so.

i can't find any article about particle test since 2015, when it mentioned the government was looking into it, i would guess they need to build a database of cars that have them first.
luckily mine never came with one but i have to admit nowadays there has to be some morality issue with gutting them.

Nothing planned for egr but the coming particulate test will detect dpf delete.
Particulate test? So even gutted DPF'S will be caught out as its more than just a visible inspection?caelite said:

Very hard to apply retrospectively.
