Does anybody else notice the fuel shut off solenoid clicking in and out on start up ?. I noticed this while I had the bonnet up and started the engine, heard an intermittent clicking and traced it to the solenoid. Obviously a necessary thing to have on a diesel as you can't stop the engine unless fuel supply is cut off, unlike a petrol engine with spark ingnition. Could always put it in high gear and stall it against the brakes to shut it down but not sure it would be good for the clutch :-).
Previous owner experienced cold start up problems if the car had been left for a while, I've noticed it a few times. He changed all the glow plugs and the common connection to the plugs but to no avail.
