my '03 Duratoq turbo diesel (1800cc) has just failed it's MOT due to higher than permissable exhaust emissions. i was told that i would be able to remedy this by giving it a good blast in the lower gears (avoiding breaking speed limits) to "clear it out". is it this simple? i want to avoid it failing at the retest (=A320) if poss so can anyone advise if this is a useful strategy? i must admit i do keep my eye on the current MPG indicator on the trip computer and try to drive most economically. should i become more lead-footed?
