WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2002 Volkswagen Cabrio, 2001 Volkswagen Cabrio, 2000 Volkswagen Cabrio, 1999 Volkswagen Jetta, and 1999 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
When removing and installing the fuel pump or fuel level sensor from a filled or partially filled fuel tank:
Be sure the ignition is switched OFF, when:
BEFORE cranking the engine at starting RPM (such as for compression testing) disable the ignition and fuel injection systems:
- BEFORE beginning repairs, the suction pipe of an exhaust extraction system must be located near the fuel tank opening so that escaping fuel vapors can be immediately carried away.
- If no exhaust extraction system is available, a radial fan (motor located outside airflow) with volume of at least 15 m3 /hr (9 cfm) may be used.
- Wear fuel-resistant gloves whenever working with open parts of the fuel system.
Be sure the ignition is switched OFF, when:
- Disconnecting fuel injection system wiring
- Connecting or disconnecting test equipment leads
BEFORE cranking the engine at starting RPM (such as for compression testing) disable the ignition and fuel injection systems:
- Disconnect the ignition coil power output stage.
- Disconnect harness connectors from all fuel injectors.
- After the work is completed, erase Diagnostic Trouble Code (DTC) memory.
WARNING:
Vehicles from 06.99 and beyond: For reasons of safety remove fuse No. 18 from fuse holder before opening the fuel system. If the fuse is in place the fuel pump can be activated by the driver's door contact switch.

- Be sure of the proper radio code (for vehicles equipped with coded anti-theft radio).
Be sure the battery negative ( - ) cable is disconnected, when:
- Working on the electrical system
- Resistance (spot) welding or electric arc welding anywhere on the vehicle.
