Checking and Replacing Fuses in VW Polo mk4

Caution!

Using the wrong fuse, using a blown fuse that has been repaired, and using metal objects in place of fuses to complete the electrical connection in the circuit can cause fires and serious personal injury.

  • 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 same overall size.
  • Never repair fuses.
  • Never replace fuses with a metal strip, a paper clip, or a similar object.
