    What I have read is I need to drive the car at speeds greater than 68 mph for 25+ mins with more than ½ tank of fuel and the regen should happen automatically during that period. Do I have to stay above 68mph for the full 25 mins?! I tried doing this at the weekend but had to slow down a couple of times for traffic. If so I shall have to try again late at night when no cars are on the motorway! Also is there a way of finding out if it has worked? Thanks!
    Diesel particle filter (DPF) and NOx cat on petrol engine are two totally different things.

    Yes I know! But thought someone may still have an answer for me.

    Awesome info! Saved for future reference! Kind of makes a carly purchase worth it as you can monitor dpf.

    Would a clogged DPF negatively affect MPG?
