Checking and Replacing Fuses

The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary.

  • Switch off the headlights, the ignition, and all electrical consumers.
  • Open the appropriate fuse box.
  • See diagrams below for details about which fuse to check.
  • Remove the fuse using the plastic tweezers located on the fuse box cover.
  • Check if the fuse is blown – if the thin metal strip inside is broken, the fuse has blown.
  • If the fuse is blown, replace the fuse with a new fuse of the same amperage (same color and same imprint) and the same overall size.
  • Replace the cover.


  • Never replace a fuse with one that has a higher amp rating. Replace a blown fuse only with a fuse of the same amperage (same color and same imprint) and the same overall size.
  • Never repair fuses.
  • Never replace fuses with a metal strip, a paper clip, or a similar object.
  • If a newly replaced fuse blows again after a short time, the electrical system should be checked by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
