So you have just paid to have your DPF removed....

But can you explain the logic behind that? It's not as if the test's demanding anything be retro-fitted. The tests for DPFs and the like are merely testing stuff that was on the car when it was new. If it wasn't on the car from new, then it makes no difference to the test. Seems to me that the test's no different for the older (and - I'd agree - better) car.
I have been told that the regulations will be gradually updated to state that vehicles MUST have certain features to pass a test in future... the older vehicles don't come with these features and would fail automaticallyIIRC this is one of the reasons why pre 1959 vehicles are now MOT exempt

They aren't great for doing lots of short trips, but then again why on earth would you buy a diesel to do that? Millions of cars have DPFs that work ok, why do you suggest they aren't fit for purpose?

On a related note, if you've removed your DPF I assume you have declared this to the DVLA so they can re-evaluate the amount of VED you pay based on your new emmmissions.
Oh, you haven't
THIS is why the Government is interested. Not the environment. But Tax. It's ALWAYS Tax
If that was right then the roads minister in question would just be making the case that all changes which affect taxation class have to be declared for re assessment.That's not exactly what the control freak and his cronies are actually saying.It's more a case of the thin end of the wedge to outlaw any car that doesn't fit into their narrow vision for the future.

That seems to suggest that any car made since 1959 will automatically fail the MOT if it doesn't meet the required standards such as catalytic converters etc etc etc let alone post 1959 cars which have been subject to major tuning modificatios from standard spec as they were when new.Which,in that case would mean the death of the classic car enthusiast market and the tuning modifications industry.
Without wanting to blunder into the (already covered elsewhere) MOT exemption debate... 
that is an issue for concern that will rear it's head in the future

Well....thousands of customers out there....
Car is immaculate, no expense spared and FSH. Depends if I decide to sell obviously.
DPFs are simply not fit for purpose. Hence why guys like me gutted or removed them. Since doing so the car is a pleasure.
If it don't sell I'll keep it. I'll be f
ked if I am going to cave into peer pressure...
But it won't have an MOT so who will buy it?. Scrap I guess.Car is immaculate, no expense spared and FSH. Depends if I decide to sell obviously.

Fair enough. If you remove something like a catalytic converter, horn, wheel or brakes that a car had when new and standard then so it should fail the mot.
What happens in the case of someone changing not removing the engine,brakes,transmission,exhaust,suspension and wheels amongst a few other things on a post 1959 car under those rules.The fact is aftermarket changes to a car's spec have always ( rightly ) been a grey area given the benefit of doubt in favour of the owner and modifier.It's called freedom.

VED is based on CO2 emissions. The DPF doesn't reduce CO2 emissions, why on earth would you think that the VED band would change if a DPF was removed?Oh, you haven't

Dont think the MOT testers will be too chuffed if they now have to have specific OBD diagnostic equipment to check with.
Could do it on temperature but only from cold - hot - cold. Without the internals they will run cooler and then cool quicker - but that then means a whole raft of data required to compare against and the extra time taken to check.
DPF's are a joke, albeit expensive ones. Chap came to me with a 57 plate Focus with the light on. Ford quoted circa £900+vat for it to be fixed! He bough one off the internet but still cost £400.
You can understand the reasoning behind removing the damn things when short journeys block the bloody things up and in some cases force the car into limp home mode.

And now the government has changed the rules, and in April the Mot test will check for one present if it was fitted with one as standard...

what's going to happen to all those vehicles where they have been cut out and removed and the ECU reprogrammed? My mate recently paid £400 to have it taken off his Mercedes Sprinter...
Is he stuffed?
Are the dealers rubbing their hands in anticipation of a lot of DPF sales?
How is anyone going to know it's off? :/https://www.gov.uk/government/news/new-rules-for-m...

However.
Technically a car with DPF removed is now operating outside the Type Approval the manufacturer originally got for the car. So technically, and I appreciate this is virtually unenforceable, The car is not legal for use. Who knows where that may end up if insurance companies get wind of it.
As per the people above grumbling about DPF fitment. If they just bought the right car for the job, it's much less of an issue. Fleet guy doing 30K a year. Absolutely fine with DPF. Idiots who live in cities and do <10K a year and "want a diesel 'cause the fuel is cheaper and I get more M PEE Gees" maybe not so much

Cars do not have to conform to their type approval to be used legally on the roads. They only have to conform to type approval to be sold as new by the original manufacturer. Otherwise every single after-market brake kit, suspension kit, alloy wheel, remap etc would make the car illegal, and the fact is they don't.Technically a car with DPF removed is now operating outside the Type Approval the manufacturer originally got for the car.

Nowhere, providing (as with any modification to a car) you have declared it to your insurer.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
