with the Fuel Delivery Unit Installed
Special tools, testers and auxiliary items required
• Adapter for Fuel Extraction (VAS 5190/3)
• Test Instrument Adapter/DSO (5-pin) (VAS 5565)
• Remote Control (V.A.G 1348/3A)
• The fuel supply line is under pressure. Always wear protective eye wear and protective clothing to prevent injuries and fuel from coming in contact with your skin. Wrap a cloth around the connection before removing a fuel hose. Remove the hose connection carefully to release the pressure.
• Connect the fuel extracting device (VAS 5190) ground sire to the vehicles ground strap.
- Disconnect the supply line (metal coupling) - arrow - and catch any leaking fuel with a cloth.
• Press the lock ring to release the fuel lines.
- Connect the fuel extracting device (VAS 5190) and adapter for fuel extraction (VAS 5190/3) to the fuel supply line.
- Remove the rear seat bench.
- Remove the cover - 1 - and the fuel pump control module - 2 - from the fuel delivery unit.
- Disconnect the connector - A - from the flange on the fuel delivery unit.
- Install the test instrument adapter/DSO (5-pin) (VAS 5565) between the connectors on the fuel delivery unit and cover.
- Connect the remote control (V.A.G 1348/3A) to the test instrument adapter/DSO (5-pin) (VAS 5565) and battery positive (+).
• This step allows the fuel pump to run when the engine is not running.
- Remove the cap from the fuel filler tube.
- Operate the remote control (V.A.G 1348/3A) and the shut off valve on the fuel extracting device (VAS 5190) until the fuel tank is empty.
Do not run the fuel pump when it is dry.
When the Tank is More Than 3/4 Full
Secure the fuel extracting device (VAS 5190) ground wire to a bare area on the chassis.
- Using insulating tape, apply a mark on the suction hose - arrow - at length of 990 mm - a - from the end of the hose.
- Remove the cap from the fuel filler tube.
- Slide the suction hose into the fuel tank until the mark applied - arrow - earlier aligns with the fuel filler tube.
• The shaft piece - 1 - is not used!
• A flap is located in the fuel tank on the lower end of the filler tube. It must not be damaged by the suction hose. Therefore slide in the hose only up to the mark applied earlier.
- Empty the fuel tank as much as possible via the fuel filler tube.
- Carefully pull out the suction hose.
• When no more fuel can be extracted, the tank is emptied only enough for the flange to be opened without danger. The tank may be removed while containing the remaining fuel.
• To drain the fuel tank completely, refer to => [ When the Tank is Less Than 3/4 Full ].
When the Tank is Less Than 3/4 Full
- Remove the rear seat bench.
- Remove the cover - 1 - and the fuel pump control module - 2 - from the fuel delivery unit.
The fuel supply line is under pressure. Always wear protective eye wear and protective clothing to prevent injuries and fuel from coming in contact with your skin. Wrap a cloth around the connection before removing a fuel hose. Remove the hose connection carefully to release the pressure.
- Disconnect the connector - 1 - and the fuel line - 2 - from the flange - 3 -.
• Press the lock ring to unlock the fuel line.
- Remove the lock ring using the wrench (T10202).
- Lift the sensor flange.
- Insert the suction hose from the fuel extracting device (VAS 5190) as far as possible into the fuel tank and extract the fuel.
If the tank only needed to be drained, then reinstall the sensor flange. Refer to => [ Fuel Delivery Unit ] Fuel Delivery Unit.
