if you drive the car in summer and all is fine, will it not still be fine in the winter?
Does it make any difference if the webasto water pump is not running, could that cause over heating?
have you a multi meter to check the glow plug resistance?
If you want a working FBH pm Deivlish or Trebor, members here and ask them about checking the PCB as these are known to fail.
Can you hear the webasto fuel pump by the near side rear wheel intermittently coming on and off? I am assuming you are left hand drive?
