Hi
I have a problem as described below and wondered if you could advise?
My Doblo is a Multijet 1.9.
My problem is this, I drive the van, it runs fine. When I jump back in after a few minutes, it starts, runs for 10-15 seconds then dies. I can leave it for a minute try again, the same ,it dies. But if I leave it till it goes cold it starts and runs fine, sometimes for a few days, other times just a few hours! Then it happens again. I am not getting any engine management light. Also when it has been running fine and up to running temp., if I switch off then start her up immediately, fine no problem. It just seems to be when it's been a short journey warmed up, then cooled a bit.
It's really doing my head in! I've done the EGR, thought it might be that! I have also done the crankshaft senor and the camshaft sensor and the heater plugs. It took a turn for the worse yesterday, now even when cold, it is starting and then dying as described above
Today a friend put it on his diagnostic computer, still no engine management light but these codes,
P0380, P0704, P0683
Getting to the end of my tether!!

Any suggestions would be appreciated
Jim
