hi,im looking for help with a 2006 tdci connect.1753 euro 3.180k. the glow plug lights flashes ,then the van cuts out. i reset it by switching the ignition off /on. this can happen quite a lot on a short run. i used a maxiscan ms300 & got dtc code p0251 ( injection pump metering control a) i have since fitted a new fuel filter(,old 1dirty, but no swarf/metal bits). i did find the pipe from the air filter to the turbo badly split. which will be replaced soon.( taped for the moment) what can the problem/s be. the van starts & ticks over fine.little bit of black smoke when revved. any ideas? thank you. steve.
