Check the circuit (wiring and connectors) between the EGR valve and the ECU.
Thanks for your reply. 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! Wondered if it's the crankshaft sensor or maybe some kind of temperature sensor. I've done the EGR, thought it might be that!
Any suggestions would be appreciated
