In this article, you will find information about the fuses of the Volkswagen Multivan (T7/ST) (models 2022, 2023, and 2024), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in VW Multivan T7
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.
