Engine Performance problem
2009 Questions for all other cars 4 cyl Front Wheel Drive Manual 7000 miles

The car is 6 month old this problem occours at about three week intervals, whilst driving at around 30 to 40 MPH the car will surge as though the fuel is bieng cut of and on after a few minutes, it will clear, if the car slows down to under 10MPH or you come to a rest then pull away the engine cuts out, without warning, the engine will restart immediatly.
My wife then gets nervouse around the three week mark waiting for it to re-occour, wich it does.
I have had it back to the dealers for a the onboard computor to be checked and to ensure the latest updates are on the computor.
This was checked twice, the third time the garage said it was pointless checking the computor as it was up to date with the software.
It haoppened again exactly 4 weeks later this time when I phoned they told me to bring the car in and they would down load a upgrade for this problem from Citroen.
Again four weeks later the problem re-ocoured this timecausing a minor fender bender, again the dealer said no fault registared on the computor, It happened again three weeks agoand the dealer said he could do nothing as Citreon had not given any feed back. then again it happened yesterday three weeks later. the engine just cuts out but restarts immediatly. I have concluded that the car is a diesel the only way to stop it is to remove the fuel or reduce the pressure in the high pressure fuel system.
I would be greatfull fr any assistance with this problem
