Special tools, testers and auxiliary items required
• Remote Control (V.A.G 1348/3A)
• Multimeter (V.A.G 1526D)
• Connector Test Set (V.A.G 1594C)
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 adapter (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 the (V.A.G 1594C) to chassis ground.
- Route the (V.A.G 1348/3A) toward the front in the 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.

If no operating noise can be heard:
- Connect multimeter between terminal - 1 and 5 - of harness connector for voltage measurement.
- Press the switch on the remote control.
• Specified value: Approximately battery voltage.
If the specification is not obtained:
- Repair the open circuit in the wiring according to wiring diagram.
If specified value is obtained, although no running-noise can be heard at pump:
- Remove the fuel delivery unit. Refer to => [ Fuel Delivery Unit ] Fuel Delivery Unit.
- Check the electrical wires between the locking flange and fuel pump to make sure they are connected and routed correctly.
- If no fault is detected in the electrical wires, replace the fuel delivery unit.
- Install the fuel delivery unit while following the information on connecting the battery => [ Installing ] Fuel Delivery Unit.
