Vehicle system and function
The control unit regulates the pre-glow time of the six glow plugs depending on the coolant temperature and switches them via an internal load relay. The glow current is protected by an 80 A strip fuse; via the lamp outputs it controls the pre-glow indicator lamps in the instrument cluster.
Installation location: In the engine bay; the 80 A strip fuse sits under the cap of the control unit.
Condition: Used genuine part (date code 89), white print with circuit diagram partly rubbed off, a cut-off cable stub at the screw terminal, housing dusty with fine scratches.
How to recognize a defective part
  • ● No pre-glowing at all, indicator lamp absent (80 A fuse blown)
  • ● Glow relay sticks and switches while driving
  • ● Indicator lamp fails even though the plugs are glowing
