Special tools, testers and auxiliary items required

• Fuel Inj. Pressure Gauge-CIS (V.A.G 1318)

• Pressure Gauge Adapter (V.A.G 1318/10-12) and Adapter (V.A.G 1318/15)

• Remote Control (V.A.G 1348/3A) with Adapter Cable (V.A.G 1348/3-2)

• Measuring container, fuel-resistant

Procedure






- Observe test conditions. Refer to => [ Test Conditions ] Initial Inspection and Diagnostic Overview.

- Remove the right 1/3 rear seat.

- Remove the bolts - arrows - and remove the locking flange cover - 1 -.

- Disconnect the electrical connector - 1 - on the locking flange.






- Push the circlip - 1 - upward - arrow A - and compress the release - arrow B -.






- Press on the marked location - arrow A - and remove the cover - 2 -.






- Release the latch - arrow B - and open the cover - 1 -.

- Connect the (V.A.G 1348/3A) using the (V.A.G 1348/3-3) and cable from the (V.A.G 1594C) to the terminal - 1 -.






- Tape the (V.A.G 1348/3-3) with insulating tape - arrow - to prevent a short circuit.

- Connect connector terminal - 5 - with an adapter cable from (V.A.G 1594C) to chassis ground.

- Route the (V.A.G 1348/3A) toward the front in engine compartment.

- Connect the alligator clip to the battery jump start terminal (U6) - A - in the terminal 30 wire junction 2 (TV22) in the plenum chamber.

- Remove the cover from the fuel filler tube.

- Remove the bolts - arrows -.






- Remove the air duct - 1 - and the air filter housing intermediate flange - 2 -.


There is a risk of injury because the fuel is under high pressure.

• To reduce pressure in fuel system, lay a clean cloth around the connector and carefully loosen connector.

- Remove the fuel supply line from the high pressure pump - arrow -.






- Connect the (V.A.G 1318) with the (V.A.G 1318/11) and (V.A.G 1318/15) in the fuel line.






- Push an assisting hose - arrow - onto it and hold it into a measuring container.

- Open the pressure gauge shut-off valve.

• The lever points in the direction of flow.

- Generate pressure in the fuel system by pressing the switch on the remote control and slowly closing the shut-off valve on the pressure gauge.

• Specified value: 4 bar positive pressure.

- From this point on do not move position of shut-off valve.

- Empty measuring container.

- Press the remote control switch for 15 seconds.






- Compare quantity of fuel delivered with minimum delivery rate in diagram (cm3/15 s).

• Voltage at the fuel pump with the engine stopped and pump running is approximate. 2 volts less than battery voltage.

If minimum delivery quantity is not obtained, the following malfunctions may be present:

• Fuel lines pinched.

• Fuel filter clogged.

• Fuel pump faulty.

Assembly is performed in reverse order.
