Best way to quickly lower the emissions would be to dump some Redex Diesel
Treatment in the tank, find a quiet road somewhere where you are going to
bother anyone and rev the nuts off your engine. You will get worrying
clouds of black smoke for a few minutes, but this will fall off as the
engine cleans itself out ;)
When you go for the actual retest make sure your engine is nicely warmed
up as this also helps a bit.
