Check the solenoid that powers the glow plugs.  If the preheat current
is not sufficient, the engine doesn't get warm enough for the prestart.
Also check the connections to that whole circuit.  I don't know why
bleeding it would help.  But maybe someone else has some other
experience.  If bleeding always helped, then I would be suspicious of a
bad fuel line or a poor seal on one of the filters, letting air into the
fuel system.
