How do you bleed a diesel engine in a peugeot 405 1995 model?

To bleed the diesel engine in a 1995 Peugeot 405, first, ensure the vehicle is turned off and safely secured. Locate the fuel filter, and loosen the bleed screw on top of it. Pump the manual fuel pump (if equipped) or turn the ignition key to the "on" position several times without starting the engine to allow fuel to flow and purge air from the system. Once fuel flows steadily from the bleed screw, tighten the screw, then attempt to start the engine.
