AGCO - F311200180020 - Glow Plug Valve Fendt

This glow plug valve controls the electrical supply to the engine's pre-heating system. It sits in the wiring harness between the control unit and the glow plugs, switching current on and off based on the engine's start cycle. A failed valve prevents the glow plugs from reaching operating temperature, causing hard starting or no-start conditions in cold weather. The original component matches the housing's electrical connector geometry and internal switching logic, so the pre-heat cycle timing is preserved. On installation, verify the connector locks fully and the mounting bracket is secured.
