In this article, you will find information about the fuses of the Volkswagen Passat (B6) (models 2005, 2006, 2007, 2008, 2009, and 2010), 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 B6
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.
Engine Compartment Fuses and Relays
Opening the fuse box in the engine compartment:
- Open the engine hood.
- Move the release buttons (1) in the direction of the arrows to unlock the fuse box cover.
- Remove the cover (2) upward.
- To install, place the cover on the fuse box. Slide release buttons against the direction of the arrows until they latch with an audible “click”.
