New MOT rules - bad news for some!

The article in Autoexpress, has a picture of a mechanic wielding a socket and wrench, on what appears to be a DPF.
If MOT testers are going to be undoing exhaust systems, that poses the question, what happens if a bolt snaps, or other damage is caused?0 -

So if there is no DPF (where there should be) or it appears modified (eg. welding marks) = MOT fail.
And I guess in case they can't easily access the DPF to visually inspect it they may just ignore it and issue a note on the MOT certificate, e.g.. my wife's car gets a note each year saying they could not check the rear seat belts due to the car child seats fitted.
I don't expect the new MOT check to be as stringent as in Germany, where from 2012 the TÜV check diesel particulate matter emissions with a second generation smoke testing equipment, plus they also get live data through the car's OBD port, e.g.. no DPF data present or any emissions error codes present = fail."Retail is for suckers"

More overthinking here. From Feb 2014 the additional check on diesels will be to confirm if a factory fitted DPF is still present. As ever, no dismantling allowed and only VOSA approved tools can be utilised in an MOT test (only recently have mirrors been accepted). So it's still the case that if a diesel has the canister in place and passes the smoke test, even if the NT is suspicious about its internals, he can only pass and advise, not fail. Biggest talking point about this with NTs is that VOSA haven't provided a reliable guide to which cars do have DPFs from new.0

This is my worry. I drive a fairly modern diesel (06 Ibiza FR TDi)
It came with a Cat, but no DPF
Cat has been removed as part of a performance exhaust system upgrade.
Now i'll probably need to take my old original exhaust downpipe in with me during any MOT's to show the inspector it came out the factory with a cat and not a DPF (and hope he knows how to tell the difference!)All your base are belong to us.0 -

What if the factory fitted DPF gives up the ghost, and OEM ones are no longer available?
The rules for the MOT test will likely state "On a vehicle where a DPF has been fitted as standard, a missing item will be a reason for rejection"
So if your car was manufactured with one, and at some point during it's life it's removed and not replaced with another DPF, then it will be a fail.All your base are belong to us.0 -
That doesn't exactly answer my question Retrogamer.
You have a car, which came out of the factory with a DPF fitted.
It now ether doesn't have one, or the one it has is defective, so you arrange to have one fitted, only to learn that the OEM one is no longer available.
Will a pattern/compatible one do instead?0 -
yes it will be ok0

Yes, it will be fine unless it is defective and causes an excessive leak of the exhaust gasses or is in such a condition that it causes the vehicle to fail the smoke density emissions test.All your base are belong to us.0 -
Arghhh...all the proposals i read online said DPF delete = fail for a diesel. No problem i thought as no mention of the cat. I seen the notification for MOT testers today and the cat being removed on a diesel will be a reason for failure as well.
A performance downpipe on my car with a cat on it isn't cheapAll your base are belong to us.0
