Hi Trev Thanks for the reply, a lot of my journeys are only about 20-30 mins long but on this particular day i had been driving the car for around an hour, I used to have a citroen c8 (for my sins) & every so often that used to regenerate the dpf, and as i have only had my voyager for a month was not sure if they did the same thing. now i know that,s one worry out of the way. Regards Mark
