I've asked if this dates right back for ANY vehicle of only for newer emissions models, but no one has yet been able to give a definitive answer

I think it will prob date back. I believe that's recorded in the vin.

i think you correct...but what goes on re dpf is for emmisions test/mot install..then remove after...very common pratise in hgv world..(where dpf has been norm for ages in london)

Or cut it open and remove the gubbins and weld it back up?

they can tell it's empty by the lack of heat

I suppose you could just do the tried and tested cat and dpf on for the test and the take them off till the following year?

Bit dodgy of you have a smash etc tho I imagine

he was talking about having to remap it so the ecu wouldn't keep overfuelling the engine etc........ too many variables so he deemed it to be not such a great money saving exercise.

not dodgy..last thing they would look for...

as i said standard practise to fit then remove...at £3000-£5000 for exhaust just to av romanian pikey nick it and weigh it in for £100..so...

An I right in thinking an MOT tester cannot remove anything, and can't fail something they cannot see? If that's the case, just fit a 'protective cover' over it...

yep that is correct, although could they ascertain whether you have one fitted from exhaust emissions etc?

i dont know, i am just wondering

Not on an older vehicle since they pass their tests without one anyway!

It only applies to those that were fitted compulsorily from new , so if it had one , not as an option , then it will need it to be functional on test.
