I am told that mot regulations will become more stringent and that it will be more than just a visual check in future. I was talking to a mate last night who manages a garage and they've just had to buy a load of new testing equipment. Sorry if this is a bit vague but I would suggest checking this out before you go ahead.

I never had any dpf problems with my cr. I just got rid as it was too slow even with a stage 1.

An mot center would not be able to tell, cut and welded on the seam and without removing it you would not know, if the car will not even start without a new one £1000 pounds fitted for a new one or delete it is a no brainer. The new checks are for catalyst removal

Bullet points here http://uk.autoblog.com/2012/01/04/changes-to-mot-rules-in-2012-are-you-ready/

The new MOT rules specify a visual check to confirm presence of the DPF or Catalytic convertor. Shark Performance open up the dpf,remove the internals and weld it back up so it will pass the visual check.

That's not correct. The new MOT rules only specify a visual check of the cat on a petrol, not diesel, and make no mention whatsoever of DPFs. There's a lot of misinformation going round about this at the moment. There is still no MOT requirement for cats on diesels.

Pretty sure the black soot comming from the exhaust would give the game away.......

Well I had a tipo diesel in the 80s without a dpf and no black smoke from mine. Usually a bad map or glogged injectors the cause

You only really get black smoke on a modern non-DPF car when the engine is revved hard after a prolonged steady run.

This is why you should always give the car a good thrash on the way to the test centre, the engine is nice and hot and any soot/carbon is burnt away.

I've just checked the VOSA website and it only mentions catalytic converter. There is no guarantee that DPFs won't be included in the future.

If you get it removed it I would be interested to see what improvement in performance and MPG you get, and how much your insurance goes up.

How would they know it is not there, why would you inform them, not a performance upgrade?

I agree there's no guarantee it won't be introduced in future, but I suspect it would only apply to cars built from some future date. The government had intended to include a visual check of the cat on diesels but this was scrapped at quite a late stage. I think the government would probably have liked to have included DPFs in that too, but there is a big problem in enforcing it, namely that VOSA don't appear to have any central database of which diesel cars were supposed to have cats, which are supposed to have DPFs, and which have neither. Until they have some official source of this data its pretty hopeless trying to fail diesel cars at MOT based on the pure speculation of individual MOT testers on whether a particular car might have left the factory with or without a cat or DPF.

The smoke limit is 3.00/m for turbo charged diesels first used between 01/08/79 to 01/07/08, the limit from 01/07/08 is 1.50/m, which is also the fast pass limit. Cats and DPFs on compression ignition engines are not part of the test. I've seen non DPF cars acheive a fast pass.

Yes, even my old R-reg Euro II, non-cat, non-DPF, Xantia 1.9TD with 150k on the clock used to scrape in under the fast pass limit of 1.50! My non-DPF PD140 Octavia records about 0.75 .Anything newer should have no trouble.

Forte have a DPF cleaner and regenerator that may help clear some of the DPF problems, I don't have a diesel but Forte seem to have a good reputation within the trade!

Paul

i've ordered some DPF cleaner and going to try this over the forthcoming days. On average now, my car is regenerating every 48 hours (with every other regen coupled with illuminated DFP light)

Given recent threads and ongoing research, I read some less than positive stories about remapping / dpf delete and not sure if this is the way to go for me now.

Totally unsure on what to do, still :'(

It depends on who does your mapping and DPF delete. Remapping is a service not a product, and it's done differently by every company out there.

We've had absolutely no problems with our DPF delete software, but the horror stories are out there and it's understandable that some stories might put you off. We might be more expensive than other people who do it, but customers use us because it works without issues. Looking back we've done 1-2 per week over the last year across 2.0TDI PD140, 2.0TDI PD170, 2.0TDI CR170 and 3.0TDI 233 and 240.

I'll also reply to your PM
