Fusible links

On models with diesel engines, the engine glow plug supply circuit is fused. This insert is located in the engine compartment above the brake booster or on the spark plug control unit behind the windscreen washer reservoir. If this insert is burned out. it means that something has happened to the system, therefore, before replacing the insert, it is necessary to diagnose the diesel engine heating system and identify the cause of the burnout.
