In this article, you will find information about the fuses of the Volkswagen Golf V (models 2004, 2005, 2006, 2007, 2008, and 2009), 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 Golf mk5
Caution!
Using the wrong fuse and attempting to re pa ir a fuse or using something instead of a fuse can cause a fire and serious personal injury.
- Never repair a damaged fuse.
- Never replace a fuse with one tl1at has a higher amp rating. Always make sure the replacement fuse has the snmeamp rating as the fuse being replaced.
- Never replace a blown fuse with a metal object to connect the fuse contacts- even not temporarily.
Location of Fuse Boxes
Instrument Panel Fuse Box:
Fuse box is located in the left side of the instrument panel. Insert the flat blade of a screwdriver into the opening of the fuse box cover. Pry off the cover.
Engine Compartment Fuse Box:
Push the lock buttons forward in the direction of the arrow to release the fuse box cover.
