Special tools, testers and auxiliary items required
• Fuel Extracting Adapter (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 eyewear 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 strap to the vehicle ground strap.
- Disconnect the supply line (metal coupling) - arrow - and collect the leaking fuel with a cloth.
• Press in the securing ring to disengage the fuel line.
- Connect the fuel extracting device (VAS 5190) with the fuel extracting adapter (VAS 5190/3) to the fuel supply line.
- Remove the rear seat bench.
- Remove the cover from the fuel delivery unit.
- Disconnect the 5 pin connector - 1 - from the right flange in the direction of travel.
- Install the test instrument adapter/DSO (5-pin) (VAS 5565) between the connectors on the cover and the fuel delivery unit.
- Connect the remote control (V.A.G 1348/3A) to the test instrument adapter/DSO (5-pin) (VAS 5565) and to the 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 dry.

Secure the fuel extracting device (VAS 5190) ground strap to a bare area on the chassis.
- Using insulating tape, apply a mark on the suction hose - arrow - at length of 1,200 mm - a - from the end of the hose.
- Remove the cap from the fuel filler tube.
- Slide the suction hose as far into the fuel tank until the mark applied earlier meets 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 neck. 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 sensor flange to be opened without danger. The tank may be removed while containing the remaining fuel.
• To drain the fuel tank completely, refer to => [ with Fuel Tank Less Than 3/4 Full ].
