300tdi cutting out

[John Coghlan]

As one of my jobs is a custodian for the National Trust I get to drive a 12 seat Station Wagon as a company car. The engine has recently started cutting out for no reason that I can find. It feels as though the fuel cut off solenoid was causing it but the connections appear to be sound after a few seconds or minutes the engine will restart, it will then run for a few seconds or more than an hour. Has anyone else had this problem. Our local garage had the vehicle for a week and found no fault. Yours hopefully Coggie


Thank you for your help, I checked the solenoid and it was OK, So I put a meter on the supply and vibration tested the wires (waggled) and I found I could make it happen when the wires were waggled next to the ECU, I eventually found that the wires where they were crimped were corroded I sprayed them with switch cleaner and then soldered each one. So far the problem has not recured

Hi, we have had problems in the past with the solenoid coming apart inside the housing,remove it and see if it is all intact.

Could be an intermittent electrical fault.... or an intermittent air ingress problem.... but first remove the solenoid and check. replace it, they arent that expensive... a 15/16 spanner required IIRC
