DPF removal check to be part of UK MOT test from February 2014

Featured Replies

From that same quote...

 

 

It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use.

 

 

The use of 'almost invariably' sounds like it 'probably will but might not'...

  • This thread has got a little rediculous. Scaremongering from people without basic knowledge of MOT testing and getting confused by mixing legalitys with MOTs. As an MOT tester the number 1 rule is

  • oops, I can see a lot of 'Wanted: DPF for a (insert car here)' topics coming soon

  • Hindsight is a wonderful thing I'm not quite sure what your big issue is with the garages, no-one held a gun to anyone's head to force them to have their DPFs removed

Guess some will be finding out for sure after February....

What is it about three letter acronyms?

HIDs

DPFs

What next?

I'll have money on the next being...

As they become more popular it's only a matter if time before people start wiring them up into the inside of their headlights!

Nope, it's illegal.  Someone posted the regs earlier in one of the other threads.  If your car doesnt meet the published CO2 levels, which are also on your V5, which a DPF removal wont, you have broken the law.

 

DPF's are known to increase CO2. Removing the DPF actually reduces the cars CO2 emissions...

 

 The use of DPF devices actually increases carbon dioxide (CO2) emissions. CO2 is the primary gas associated with global warming, and its reduction is targeted by the Kyoto Protocol. The additional CO2 is created both through the operation of the DPF itself, as well as through the production of ultra low sulphur diesel fuel (ULSD). In addition, using ULSD results in slightly poorer fuel efficiency (despite its higher cost), which contributes to higher fuel consumption and an increase in CO2 emissions.

This is true. For example the 2.0tdci focus c-max with a dpf produces 154 g/km of co2 and the non dpf version produces 149 g/km. So in theory this example of removing the dpf would actually reduce the co2 output. The 2004-2008 version that is.

If the inners are cut out and welded back together and nee software how are they to know. Only if you remove the box altogether would anyone know

'almost invariably' refers solely to DPFs that were optionally fitted.

You could optionally fit a 1999 Octavia Diesel with a DPF and it would be OK to remove it. I know because I've seen a MK4 Golf (ex Taxi from the Netherlands) with a faulty DPF and we asked the question and were told it was OK to remove it.

I thought you could test it as early as you liked but you'll only get 1 month extra on the MOT so it'd run out 13 months from test date.

If you get the first MOT done more than one calendar month before it is due, the MOT certificate will only be valid for one year from the date of the test. I had mine done one calendar month early and it is valid for 13 months.

Who on earth decides to spend £1,500+ fitting a DPF to an older car?

Up to one calendar month before it is due allows you to preserve the aniversary date.

Several people I know have moved it forward 6 months so that it is due in the summer when it nice and warm in case something fails and needs fixing.

It was an ex Taxi from the Netherlands (AHF engine) so I guess (and it is only a guess) that there may be low emission zones in the centre of some cities in the Netherlands. I believe the option was about £750 in 1999.

This is latest info on MOT testers website http://www.motester.co.uk/mot-news/mot-news/copy-of-mot-fee-frozen-until-2015 with regards to DPF.

 

A garage i know off has started ensuring that if a DPF was a mandatory fit that it is there and working before buying any secondhand vehicles. This is to protect them from future court cases of selling a vehicle which contravenes regulations. 

 

 Dont shoot the messenger :)

I might do that in the future as mine will be due next year on 18 December.

Yes I always MOT my cars in the summer. My current Octavia was first MOTd when it was 2 years 6 months old so I got a mid summer anniversary date every year instead of the mid winter date I would have been stuck with if I'd left it until the car was exactly 3 years old.

How would you go about getting a list of cars with DPF's fitted from the factory?

It would be in the type approval data for each model that has a DPF fitted as standard. I'm not sure if this is available online somewhere or not.

I may be wrong, but ISTR the type approval info states the emission standard the car complies with, but not the specific emission control equipment fitted? Hence my earlier point about it being hard to prove retrospectively whether a particular car had a DPF fitted from new or not.

The full type approval pack includes the standards met, design nominal, test measurements and equipment employed.

It was always anticipated that at some stage the MOT will be used to catch 'VED band cheats' so this information goes back to around 2001.

As was stated earlier, DPFs increase CO2 output. What do you think happens with the carbon they burn off?

 

And a Euro IV diesel will meet the emissions regulations with or without one, so it would pass the relevant test even if you remove it (pre 2008, or is it 2010, VRSs for example).

You are correct in that DPFs reduce particulates and not CO2. The submission for type approval contains both particulate and CO2 data. Type approval isn't only a set of figures - it also applies to the equipment employed. That is why you need a type approved cat from 2001 onwards.

I should imagine when this comes into force it will only be for new vehicles manufactured after that date.

Not sure what has been said in all the pages of this thread but this sounds like an assumption. The Direct Gov site (https://www.gov.uk/government/publications/diesel-particulate-filters-guidance-note) seems to indicate but not explicitly state that it will be retrospective as the removal of a dpf from a vehicle is illegal, so the mot check could well be applicable to all cars originally fitted with them.

Will be interesting to see how this goes as it could be the start of the Euro anti modding legislation via a slightly different route!

I guess only time will tell then... I've said it before on other pages on here how I predict that modified cars will be a thing of the past in not many years to come, they are making it much harder to declare engine transplants now too so that the paper work Is all legit. In some European counties it is already illegal to modify a car in any way, it will turn a lucrative busines into a backstreet underground industry.. Remaps will be following suit too, they would issue mot stations with a plug in device that scans a specific checksum or a specific parameter, of course remaps will still exist but it will just get much harder to make them undetectable , the info I heard on ecu's is that they are planning on making the EPROM chips quadruple redundant and all the internal checksums need to match which will spell the end for remaps and the rise of plug-in piggy back tuning boxes instead.
