- New rules for MOT – to test for diesel particulate filter
I have enquired about DPF removal and they open the case, remove the dpf and weld it back up. Seems common to do and no one in an MOT station will know any different. It wont affect emmisions , only soot, so not sure how they will test it. I also see, when cars depreciate, more cars coming off the road very early in their lives, due to the inherent cost of replacing such items, so the world will be struggling to dismantle and recycle a lot more cars than they currently do. Almost to the point of saturation like happened when the scrap allowance was done. The DPF is not a cure of diesels , in the same way Cats werent for cars. They are just quick cures. Which as a consumer, we will have to pay in the long term.Posted 4 years agomaccruiskeenSubscriber

Sort of – I expect these things are only expensive problems now because they’re new technology and theres an limited aftermarket and limited wisdom within the car repairing fraternity. A few years down the line though there’ll be a cottage industry off fixes and refurbishments. I used to be able to exchange rather than replace the shock absorbers on my old MGB, theres was only £12 parts and labour difference between a jiggered one I posted off and the refurbished one I got back. By the same measure with my current common rail diesel I can post off my dead ECU or EDU and get a refurb one back already coded and matched to plug in and use. I couldn’t have done that when the van was new, but now that its long in the tooth all those engines are failing in the same way, mechanics are versed in diagnosing the common faults and theres a market in fixing/re-engineering those commonly failing componentsPosted 4 years agothisisnotaspoonMember

Except cats are pretty reliable? I don’t actualy know 1st hand* of anyone having one fail.
*I’m sure I know someone on an internet forum whose friend had one fail, but not amongst the people I actualy know with cars.
I have 2 diesels in the household a Cmax and a Kangoo Van, neither have DPFs and I dont see either
neitherkick out tonnes of soot,
FTFY, unless you follow behind them accelerating away in some out of body experience?Posted 4 years agoboobsMember
I suppose there are no problems with “Gasoline direct injection” and particulate matter that is ejected from them.
IIRC mot testers can’t remove any trays or covers to check items, it’s been a while but that is how it used to be.
[Diesels are for trucks and agriculture.
In a car they just advertise to everyone that you are tight or don’t really like cars.Posted 4 years ago

Well diesel MOT’s don’t have an emissions test so the fact they won’t change doesn’t really matter,
They do have a have a smoke/soot test though.
So that’s how they would test it.Posted 4 years ago
70+MPG, £30 RFL heater + aircon, and a roof.. Your moped might do better.. but in winter a heater and a roof win it at 6am…
1) It’s not a moped. It’s a scooter. Big difference.
2) Aircon is standard on all motorbikes 🙂
3) £37 RFL for my 350cc scooter, but more than your 70mpg so I win there. Oh £80 insurance too. Beat that. 🙂
4) I’ve been commuting by bike for nearly 20 years. See Rule 5 I’ve cycled at -7c at 6.30am.
5) I’ve got £1000-ish worth of kit and heated grips. I’m as warm as you are.
6) Free parking 10 yards from work, cars either pay or park 10 mins walk away.
7) And the killer: I get there faster every single time. Over 15 miles I reckon I save 1/2 to 1hr per day over a car. What’s that worth?

Also, lets see your proof of 70mpg from you car. I’m calling bullshit 🙂
I’ve got 7354 miles worth of fuel records. Have you?beamendsMember
wow some of you guys need to stop playing internet top trumps, did you also mention who would be better off in a accident between scooter/motorbike and car? hmm thought not.
but on a slightly more serious note, i am a believer that an older, mechanical car that can easily reach 200,000+ miles without all the egr cat dpf bollocks has got to be better for the enviroment than some ecobox shit that has to be re-melted down and remade every 4-5 years when you look at total lifespan and and energy used in total, but hey maybe thats too sensible?Posted 4 years agoElShalimoMember
To test this properly they’d have to open up every Euro4/5 exhaust system paying particular attention to the sensor arrangement so they don’t break anythingPosted 4 years ago
This would mean costs massively increasing and a huge training exercise to show mot inspectors what to do as each car is different. It sounds like they have good intentions but how the hell will they implement it?
Also if you have a warranty longer than 3 years opening the dpf up will invalidate the warranty. It sounds like aload of bollox to me to simply scare peopleFlaperonSubscriber
Since a car with a DPF should produce zero on the smoke test, any car with a bypassed or disabled DPF will show a non-zero result. Can’t stand diesel soot, so if you have one with a DPF you should keep it installed.

Too sensible? No, but it is too bollocks.
Those old mechanical diesels will expire eventually. And when that happens it’s better to replace it with something that will be much cleaner and is probably MORE likely to last 200k miles. No-one’s suggesting scrapping perfectly good cars. Well, apart from the government a few years back, but that was an economic policy not an environmental one.
And why call them eco shitboxes? A new Passat is a much more powerful and luxurious car than a 20 year old one, and it’s more economical and cleaner.Posted 4 years agosingletrackbikerMember
Heard from someone within DoT that they can easily check for welded DPF units & will fail them unless you can prove it is complete. Also, fake units are apparently easily recognisable (serial numbers, CE marks etc) & will also result in a fail.Posted 4 years ago
There are plans to extend further the diesel exhaust gas testing to tighten controls.NorthwindSubscriber
Mine doesn’t have one… Are there still new models on the market that don’t?
Also passed 2 MOTs without the cat no bother (never sure about the pros and cons on that, fuel economy with the remap and decat is a fair bit better, so I’m maybe producing more nasties per litre but burning less litres, who knows). It does have more powers and less thirsts so I’ll overlook whether or not it’s killing babies.Posted 4 years ago
Dpfs get clogged with soot if not exercised often.
My cat got removed when it rotted through.
Cat on a diesel- might want to read about what that doesnt do also.
Egr is the only one i think has merit- but they need to design em to the car rather than a bolt on clog fest like both mines were.Posted 4 years ago
