Draining sediment from the fuel filter (15,000 km) (Audi A4 B5)

1. The fuel filter is mounted to the left of the engine, behind the generator (Fig. 8.1). Before starting the procedure, wipe it so that dirt does not get into the fuel system.



2. Place a suitable container under the filter. For better access, remove the high-pressure air duct from the intercooler by loosening the clamps and unscrewing the mounting bolt.

3. Loosen the bleed screw at the top of the filter, attach the rubber hose to the drain wing nut at the bottom of the filter. Direct the hose into the container underneath.

4. Drain about 100 ml of sediment (Fig. B.4). Tighten the drain plug (lamb) and remove the hose. Remove the dishes.



5. Tighten the bleed screw on the top of the filter.

6. Start the engine and check for leaks.
