How can I fix the DPF fault on my Citroen C3 Picasso?
My Citroen C3 Picasso has completed 47,000 miles without anything major going wrong. But now I have a dashboard warning light saying "SERVICE" and a message which says "Engine Fault, Repair Needed".
Just prior to this warning there was another saying "Particulate Filter Clogged". This has now disappeared just leaving the first message plus an engine management warning light. Should I try to clear the particulate filter by driving at 2000 revs for 50 miles?

It reads like a problem with the DPF, caused by the car being used for lots of short journeys. A modern diesel car, such as this, needs at least 15-miles per journey to reach optimum operating temperature and cycle the DPF.
A long drive may allow the DPF to perform a full cycle and burn off the particulates that are trapped within it. But this will not be a permanent fix if the car is used for lots of short trips. If the long drive doesn't resolve the problem you may need to have the DPF cleaned or replaced.
