1. Put redex in
2. Went for on1 hour drive in Sport mode, acclereating as hard as possible and keeping revs up as much as possible.
3. Asked locla friendly garage for 'non-MOT' emissions test.
Result: 0.4
0.4.
How the HECK did the morning MOTers get a starting figure a whole digit above???? I went back with the new test results, and asked if it was at the right temp. They claimed yes, so I suppose it must have been 'some kind of' injector clogging after all.
Who knows if it will pass when repairs are done and it is retested. If I can get it before they test so I can blast it, so much the better.
As for the MOTing Garage claiming 'The Govt is trying to legislate old cars off the road' and 'the test limits have gone up'...there is no need for that kind of blarney.

An intermittent misfire on a diesel!? The glow plugs aren't needed on these cars in this country to start, even if it is -10c they will start without glow plugs. It's one of the advantages of common rail injection.
I would be very shocked if a glow plug actually caused a misfire, it would be significantly more likely that it is the injector.
