2.8L VR6 (Engine Code AXK)

  1. Ensure battery voltage is at least 11.5 volts. Ensure fuel pump fuse No. 18 is okay. See Figure . Turn ignition off.
  2. Relieve fuel system pressure. See Fuel System Pressure Release (2.8L VR6, Engine Code AXK)  .
  3. Connect Pressure Gauge (VAG 1318), or equivalent, at fuel supply line/hose in engine compartment. Ensure shut-off lever is closed (at 90 degrees to fuel flow, position B), and fuel hose is in a measuring container. See Figure .
  4. Remove fuel pump relay from relay panel. Connect Remote Control Switch (VAG 1348) between battery positive source and fuel pump terminal. See Figure .
  5. Operate remote control at short intervals until a pressure of about 44 psi (3 bar) has built up. If pressure builds up too high, lower excess pressure by carefully opening tap.
  6. Observe pressure drop. After 10 minutes, fuel pressure must not drop below 36 psi (2.5 bar). Check line connections for leaks and/or replace fuel pump if necessary.
