Yes it has been serviced recently and almost seemed a bit worse after! I hit the trip switch each time I fill it up and would ordinarily expect to get 400 miles from each tank of diesel on my normal day to day driving and more on a long trip. If I leave it all day or all night it misses when I start it, but doesnt do it if its only been a few hours. Will try the Halfords stuff and get the glow plugs tested. It has had issues with them in the past. Had sorta ruled it out as it was starting ok.
