Diesel Particulate Filters (DPF) issues and comments

Care to link the actual legislation (for the UK) that states this, also bear in mind that a DPF is technically an aftertreatment so removing it doesn't mean removal of the the entire emissions control system.A straw-man argument if there ever was one!
It is a legal requirement to keep the original emission control equipment, whether it contains a DPF or not, in it's original design configuration, or else obtain a new type approval certificate.0 -
If an agency (this means the vast number of backstreet companies on the internet which still claim it is legal) fiddle or removes an emission related component whether it be an ECU or after treatment device it no longer conforms to type approval. It has long since been illegal, but this newer regulation more explicitly deals with tampering
4. MINIMUM INSPECTION REQUIREMENTS The inspection shall cover at least the items and use the minimum standards and methods listed below. Reasons for failure are examples of defects that may be detected.....
8.2.2. Diesel engine emissions 8.2.2.1. Exhaust emission control equipment Visual inspection (a) Emission control equipment fitted by the manufacturer absent or obviously defective

That is an EU directive.
It does not necessarily mean that it is law in the UK. Despite the deadline at the end of the document, it may not have been adopted yet or it may only apply to cars registered after a certain date. A link to the UK legislation would clarify.0 -

AFAIK, so long as a vehicle can pass the emissions test of an MOT (without it's DPF), then it'll be perfecty legal to remove it.0 -
In conversation with a ford dealer master technician I discovered that they will want around £1400 to replace the DPF filter in the diesel engines, which falls due at 75,000 miles...CRIKEY!
That particular master technician is obviously trying to con his customers. £1400 to replace a DPF? At 75K miles?
At 75K miles you just top up the eolys fluid (or whatever Ford calls it these days), reset the ECU counter so it knows how much fluid is in the tank, and check the DPF exhaust pressure (computer) to figure out the approximate DPF replacement mileage. You're unlikely to experience any DPF problems in the current shape diesel Fiesta up to about 120K* miles when the filter eventually needs replacing or cleaning.
When your diesel Ford needs a new DPF filter, the filter that your Ford garage supplies is most likely a reconditioned unit. The garage orders a "new" one from Ford for around £750, they put it in your car (2hr job) and then send the old DPF to Ford and receive a £250 (approx.) credit. Now you do the maths.
Alternatively you can have the filter cleaned at a specialist garage for a fraction of a "new" replacement cost. At this stage there are not too many companies in the UK providing this service, so all franchised dealers are cashing in while they can.
* Obviously provided that you do the appropriate mileage to benefit from a diesel engine anyway - nobody would buy a diesel powered car for short distance fuel economy (because there is no such thing), would they. But that's another story.
They are not proper companies, they are cowboys.It is not a legal requirement to fit DPFs in the UK at the moment. The proper companies remove the actual core from the DPF section rather than replacing the section with a straight through pipe. That way no one can tell it has been removed.
The one advantage of doing a DPF removal & reprogram is a large increase in mpg.
Obviously they haven't done their homework and lack the appropriate skills and equipment to properly do their job.
You don't need to remove the filter (and patch the ECU software), you simply clean it using specialist equipment.
I think there is a very good business opportunity for a specialist exhaust place where they can quickly (well, the process takes up to 24 hours) regenerate a DPF. In Germany, Holland and Italy you can have a DPF professionally regenerated for less than €200 - so I guess it it is much better value than paying a cowboy £400 to remove it. And you do the right thing for the environment and all the asthmatics out there.
No UK legislation? IMHO it is just a matter of time. Eg: London low emission zone.
I think DPF is a brilliant piece of technology. Unfortunately people buy diesel-powered cars purely because of their claimed MPG - there is this crazy mentality that everyone needs to buy a diesel to save money - and then don't know how to use them (DPF, DMF, turbo, etc.) and end up spending a fortune fixing it."Retail is for suckers"

The UK has required to conform to EU regulation for 25 years, these become automatically enshrined into UK law after about 6 months.
This is because it is pointless one country cleaning up their act if the pollution from a neighbouring country blows onto their patch. There is no specific in service regulation governing particulate at all. Smoke is not particulate. That's why the type approval particulate regulations are key and the equipment has to be there to meet them, subject to reasonable deterioration, not tampering or removal.
The regulations introducing EC Whole Vehicle Type Approval became UK law on 29th April 2009 http://www.dft.gov.uk/topics/vehicles/ecwvta
Cleaning sounds like a good option if it works, however why did it get clogged up? Is it reaching regeneration temperature due to not travelling at higher speeds or long journeys?0 -

That only applies to new vehicles, a prototype is tested and if it complies with the regulations, the model can go into production without further testing.
It doesn't cover what happens to the vehicle after it is sold......0 -

The car/light goods vehicle MOT test is about to change – the European
Commission has changed the Directive that covers it. We take a look at
when these changes are likely to come into effect and what they mean
for MOT testers.
Britain has been testing vehicles under the MOT scheme for 50 years now. Last year, the European Directive covering the MOT test was updated and revised by a
modern version called 2009/40/ EC. This was then updated by 2010/48/EU, which was ratified on 5 July this year.
See Directive 2010/48/EU
In which way does this this regulation only apply to new vehicles?
4. MINIMUM INSPECTION REQUIREMENTS The inspection shall cover at least the items and use the minimum standards and methods listed below. Reasons for failure are examples of defects that may be detected.....
8.2.2. Diesel engine emissions 8.2.2.1. Exhaust emission control equipment Visual inspection (a) Emission control equipment fitted by the manufacturer absent or obviously defective

Doesn't that directive just refer to testing procedures, many of which are still not part of the UK MoT test despite the 31 December 2011 compliance deadline?0 -
Where does it say that?0
