In this article, you will find information about the fuses of the Volkswagen Passat B8 (models 2014, 2015, 2016, 2017, and 2018), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
These diagrams are not suitable for the North American version!
Checking and Replacing Fuses in VW Passat
Only replace fuses if the cause for the malfunction has been fixed. If a new fuse blows again after a short time, the electrical system must be checked by suitably qualified professionals. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
- Switch off the ignition, lights and all other electrical equipment.
- Remove plastic tongs from either the fuse box or the cover of the fuse box.
- Depending on the design of the fuse, slide the appropriately sized clamp on the plastic pliers onto the fuse from above or from the side.
- Remove the fuse.
- If a fuse is blown, replace with a fuse with the same rating (same color and same label) and the same size.
- After inserting the new fuse, place the plastic pliers back in the cover, if necessary.
- Reinstall the cover or close the fuse box cover.
Caution!
Using unsuitable fuses, repairing fuses, and bridging a power circuit without fuses can cause severe damage or fires within the vehicle. This could result in serious or fatal injuries.
- Replace fuses only with fuses of same rating and size. Make sure that the color and label are identical to the faulty fuse.
- Never repair fuses.
- Never use metal strips, paper clips or similar objects as substitutes for fuses.
