The remap place where I went, he told me the majority of his work is people having the dpf removed and deleted, and that they spend a lot of time welding it in a concealed way, whereby none have ever been picked as altered by main dealers or mot centres and the emissions always pass. Although he said that's not future proof as they may change how they measure emissions in the future altho given the recent mot over haul I can't see another change happening for some time

The benefits he said being better economy, less stress on the engine, very slight increase in bhp, and a nicer sounding exhaust.

Isn't the dpf the thing that masks all the black smoke you sometimes see coming out of vans when they pull away. And obviously it's illegal, but at the same time it's likely to eventually break for city drivers, costing thousands.

What are people's thoughts

If you, sorry if your friend, does this then he's a selfish twat IMO. Since any visible smoke is an MOT failure since May I'd be amazed if it would pass an MOT with no DPF despite what the obviously snide remapping place say.

It was offered to me during the remap but I declined as its not legal.

However, doesn't stop me learning people's thoughts, especially as a friend is considering a remap too after me having mine done, where I mentioned they do do dpf removal at the same time at a reduced price.

Plenty of mot pass testimonials on their Facebook page since the May mot update.

I think it's daft to remove it, given that it's now known that diesel emissions have such a large impact on human health, for the sake of few extra bhp on a remap.

I'm not sure anyone doing this cares about marginal extra stress on the engine or they wouldn't be getting it remapped.

Having a nicer sounding exhaust on a diesel in like having a nicer sounding fart. It's still a fart unfortunately.

As Xenon has said the rules have changed. Visible smoke cannot be masked if you delete the dpf.

If anyone is removing a dpf over reliability concerns then I do have to question whether they bought the right car in the first place.

Particulates are taken so seriously by regulators that even petrol cars are going to need filters from this summer.

Isn't it now part of the MOT that the dpf must be there?

As a mechanical imbecile though I've no idea how easy that is to check.

So this place on Facebook is publically admitting to DPF removal? Classy.

That suggests that's similar to when you see some black smoke coming off a van when pulling away. I find it disgusting when a car in front is like that, and I'd hate any car I had to be like that.

Yes it is but this place evidently does a "discreet welding service" to cover up the fact it has been removed.

Lol yes. Just looking at the page, the majority of the 50 or so custom rolling road remaps done also had a dpf egr delete/removal, pictures of the cars included, and scores of posts saying no additional smoke evident, and all passes from the new mot test.

There's even a post showing the typical welding and repaint done looking untouched

Similar to the guy with the dash cam recording himself doing 180mph. A bit self incriminating tbh. Perhaps linking in the DfT would assist their business

[teaston]

Don’t do it, I had a pre LCI E90 320d which didn’t come with a DPF and the exhaust fumes smelled vile!

[pmgreenwood]

Cars with DPF removed may have got through old Mot's but they are not going to get through this year's onwards Tests requiring no smoke at all. the chap plainly does not know what he is talking about and hence I would place no trust in any of his advice.

[ZeroFx]

most idiots who do this can be seen from miles away as the back of their cars get covered in soot.

private hire Taxi drivers are especially bad since they use dodgy mot centers who pass them as road safe.

[madlad2000]

Thanks guys, I'm just going to show him this thread, easier lol

The DPF is there for a reason - there may be some small benefits, but hey, they're kind of outweighed in congested towns and cities.

Health issues to one side (if you CAN ignore this concern), at MOT time your wallet will almost certainly take the hit of paying for a new DPF being fitted.

[TiredGeek]

I'd be embarrassed driving a car nowadays that smokes, they just look knackered.

As for a dpf causing problems with town driving, I've just switched from a Volvo that had a dpf and I did 125000 miles with that, at least 50% around town. Yes, it occasionally (maybe once a year) gave me a warning triangle about regen required but a 20min drive on the motorway at 60mph took care of that. I think as long as you are willing to be proactive in that regard then the dpf will not cause you problems. I found in the last 30k or so that I haven't had the light once which may be a coincidence but that's roughly when I started using Millers fuel additive...….

I'm not convinced about the horror stories regarding diesel pollutants, I'm old enough to remember all sorts of scares that have since not been mentioned. Anyone remember when milk and eggs were bad for you?

[nascot]

I had the DPF removed from my old Alfa 159 a few years ago (before it was made an MOT failure). It was quite a crude system in that car and it made significant improvements. BUT, knowing what we know now about the damage caused by diesel particles I wouldn't do it now. I remember the smoke that used to come out under full throttle....not good.

[lethbridge]

New MOT specifically checks for tampering and smoke on cars that have/should have dpf. Hard to imagine a car without a dpf not smoking? I guess that is the only question and the tune will obviously have an impact. If it fails you are not allowed to drive it home so you are at the mercy of the MOT station and what they will charge to fix it or you need to transport the car somewhere yourself. Don't forget this goes beyond MOTs (so don't rely on a friendly mot place turning a blind eye) - I would expect to see checks in cities carried out by DfT/Highways/Police with the view of taking these antisocial cars off the roads...

The checks started a while back.

Can't remember exactly when but a series of garages where hit over dpf removals.

The follow ups I believe included owners of cars where work had been carried out to remove them.
