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...

https://www.gov.uk/government/news/new-rules-for-m...

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?

I saw one poster comment in an earlier thread that it won't be possible for a tester to tell if a DPF has been removed. Is this true?

The internals of a DFP, I think.

If the original DPF has been gutted, then no. If it's a decat type pipe welded in place, then yes.

He's fked it needs to be on.

As for dpf's they are rubbish they don't reduce the level of emissions they store the harmful particulates then once it needs a regen it burns it and chucks it back out the exhaust pipe it's the single worst invention to be put on a car.
But on the other hand a lot of people buy diesel's just for short journeys which is stupid and now they are paying for the "diesel is better" proper gander that seems to be everywhere. I will never ever own a diesel car will keep to my petrol thank you very much.

This is the reply I got from the DfT when I asked them the same question:

"We are working to assist MOT testers in determining as quickly and efficiently as possible whether a particular vehicles must have a DPF fitted to remain legal. For example we are currently engaging with vehicle manufacturers to develop a vehicle list that could be supplied to testers with applicable information to determine factory fitment and therefore removal.

It will evidently not always be possible for the tester to tell, but there are likely to be many cases where this is obvious. We will however be looking further at precisely what steps we can take to determine the DPF status for a particular vehicle, which may include enforcement activity."

A simple temp check of the exhaust, job done.

Which it won't be unless the MOT test is being conducted on a motorway!

I've never known MOT testers to worry about this kind of thing.

If it's safe = pass

When you do an mot test as I do the cars are up to temp for the exhaust test, if a dpf is present the before and after temps will be different. Doesn't need to be re gening for that to take place.

I have no real issues with the test but I do feel it's starting to force the older and in my eyes better cars off the road.

Is that a joke? Testers these days are well aware that the VOSA inspector is always about checking... They now sit outside test stations logged on the system, and when the Tester finishes the test, they go into the garage and check the car over. Its all much more stringently policed these days and no tester want to lose his licence if he has passed a car when he should not have.

We can debate the rights and wrongs of the inclusion of DPF's into the test, but from April, if its not there then its going to fail, safety wont come into it.

I suspect they will also be looking into a more sophisticated check for the future...

That's an interesting comment Carl... If that's the case, a simple test of before and after DPF temperature check with a cheap infrared thermometer could potentially indicate if the innards have been removed or not...

That's the whole point; it burns the particulates so that they are a gas, and not particulates anymore.
