How do you bleed a diesel filter on a peugeot 405?

To bleed a diesel filter on a Peugeot 405, start by ensuring the engine is off and cool. Locate the bleed screw on the filter, usually at the top, and use a suitable wrench to open it slightly. Then, pump the fuel priming bulb until fuel flows steadily from the bleed screw, indicating that the air has been purged. Finally, tighten the bleed screw and start the engine to ensure it runs smoothly.
