In this article, you will find information about the fuses of the Volkswagen Passat (A34; models 2019, 2020, 2021, and 2022), 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 Passat (A34)
Caution!
- A fuse with too high amperage could damage the electrical part and cause a fire. Do not use a fuse with a higher amperage than the fuse being replaced.
- To avoid damaging the electrical system, turn off all lights and accessories and remove the ignition key before replacing a fuse.
Fuses in the Instrument Panel
The fuse box is located behind the storage compartment. For access, pull the storage compartment strongly backwards out of the brackets.
