Air in my diesel fuel system

I have the a Citroen Berlingo with the 1998cc HDI engine. It has nearly 160,000 miles on the clock, and has been fully serviced. Runs brilliantly, except on very short start/stop runs from cold on damp days, when some air gets into the fuel lines and has to be cleared.

Once I've done about five miles it never happens. All the pumps and bits have been checked by my trusted garage, all okay. Once it starts the fault has disappeared until the next time. It does happen on damp days, I don't remember a warm dry day when it happened. The car is kept outside.

Probably a worn pump. But the old 2.0HDI does have a very good reputation. I've been taken to the airport in a 406 2.0HDI with 300k miles on it, and it still felt good.
