The way this works is that regeneration happens on average every tank of fuel , so if you dont have a 20 minute run on the motorway at least once or twice a tankful you will get a message "Soot Filter full"
There are three stages to this
1 What you must do IF this message comes up is to go for a 20 minute motorway run as soon as possible . This will regenerate the filter and all is ok . YOU fix the problem , there will be a fault code stored in the sytem to let the service people know what's been happening .

2 If you ignore the message then it will go into limp mode and this regeneration will have to be done at the dealer on the computer , it takes over half an hour . And 2 codes will be stored to indicate that the first soot message was ignored ...

The third stage , if you ignore the limp mode for long , you will have to buy a new particle filter .

The emissions are very clean on this engine if you look at the tail pipe it will be clean with no soot . The particle filter is how this is achieved and with average driving you won't get a problem . You don't need an additive topping up every 36000 miles OR the particulate filter changing at 72000 miles as the Ford based engine in the s40/V50
Also a motorway trip will do ANY car a lot of good if its mainly used for short runs .....so make a small alteration to your driving and you wont even get the soot message at all .
