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.
Notice
- 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.

- Fuses on fuse holder A -SA- (On the electronics box, on left in the engine compartment)
