To test the battery, use a multimeter to measure the voltage. A fully charged battery should read between 12.6 and 12.8 volts. If the battery is reading less than this, it may be time to replace it.
Blown Fuses
If a particular electrical component or system in your 2009 VW Tiguan suddenly stops working, it may be due to a blown fuse. The fuse box is located on the driver’s side of the instrument panel, and can be accessed by opening the driver’s door and removing the cover. Use the diagram on the cover to identify which fuse corresponds to the component or system that isn’t working, and replace it with a fuse of the same amperage rating.
Loose or Corroded Connections
If you are experiencing intermittent electrical issues or poor performance, it may be due to loose or corroded connections. Check all of the wiring connections in the affected area, and clean them with a wire brush if necessary. Make sure that all connections are tight and secure, and that there is no corrosion or damage to the wires or connectors.
