Replacing fuses

Bilt Introduction

Due to the constant development of the vehicle, equipment-dependent fuse allocations, and the combined protection of multiple electrical equipment items using one fuse, a complete overview of the fuse layout is not available at the time of print. Detailed information about fuse allocations can be obtained from suitably qualified professionals. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Generally, multiple electrical equipment items can be protected together through by fuse. On the other hand, some equipment items may use multiple fuses.

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.

WARNING

High voltage in the electrical system can cause electric shocks, serious burns, and fatal injuries.

  • Never touch the electrical wires in the ignition system.

  • Avoid short circuits in the electrical system.

WARNING

Using unsuitable fuses, repairing fuses, and bridging a power circuit without fuses can causes fires and serious injuries.

  • Never install fuses that have a higher amp rating.

  • 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.

NOTICE

To prevent the risk of damaging the electrical system in the vehicle, the ignition, the lights, and all electrical equipment must be switched off before a fuse can be replaced.

  • Make sure that the ignition cannot be switched on while a fuse is being replaced.

NOTICE

If a fuse is replaced by another fuse with a higher amp rating, this could also damage the electrical system in another location.

NOTICE

Dirt and moisture in the fuse boxes can damage the electrical system.

  • Protect open fuse boxes from dirt and moisture.

NOTICE

To reduce the risk of vehicle damage:

  • Carefully remove and correctly re-mount the covers of the fuse boxes.

There are more fuses in the vehicle than are specified in this chapter. These should only be replaced by an authorized Volkswagen dealer or authorized Volkswagen Service Facility qualified in this respect.
