Just run it on 4th gear @120km/h (75 mph) on the motorway for 30 minutes every now and then. It has worked for me. My daily commute is like you describe, 5km to work, the motor hardly reaches 80°C temperature. But then twice a year I do 2700km round trips where I am almost always above 2000rpm during 2 consecutive days...
On my previous car, you could tell when it was attempting to regen by checking the instantaneous MPG. If you take your foot off the gas while coasting along it should normally show a really high figure, or just ---, I can't remember what the Berlingo does now.
If it's trying to regen then it won't show this really high figure, as it will still be taking some fuel to make the exhaust get hot. If this is the case then drive up and down an A-road until it clears.
If it's trying to regen and never completes then you'll get rubbish MPG, as it ends up permanently trying to run extra hot but never actually completes.
I don't know whether the above actually applies to the Berlingo though - I'd guess so, but I could be wrong.
thanks a lot guys for the advice, I don't mind fast idling outside asda once a week while I wait for the other half, 15mins ok? when I put my foot down now and again you no hard exelerating in 2nd and then third I see a bit of black smoke come out the exhaust is that the carbon leaving the filter ?
oh guys is the asda diesel the same as say bp or shell and is it worth putting an additive in the tank when I next fill up

Buy Shell or BP & you won't need additives.Having said that,I still add Millers to my,mostly,Shell fills.
