Replacing fuses

Fig. 171 Left side of the engine compartment: fuse cover 1

Fig. 172 Left side of the cockpit: storage compartment (left-hand drive) 2 or storage compartment (right-hand drive) 3

Fuses are installed in various locations in your vehicle.

The following information only lists fuses that you can change yourself. To have other fuses changed, contact an authorized Audi dealer or authorized Audi Service Facility. The following table does not list fuse locations that are not used.

A fuse that has blown will have metal strips that have burned through.

The fuses are located in the left side of the engine compartment 1, or behind the storage compartment in the left side of the cockpit 2 (left-hand drive vehicles) or the glove compartment 3 (right-hand drive vehicles).

  • Switch the ignition and all electrical equipment off.
  • Check the table that follows to see which fuse belongs to the affected equipment.
  • Remove the screwdriver from the vehicle tool kit.
  • Remove the appropriate cover.
  • Remove the clamp from the rear side of the fuse cover 1.
  • Remove the fuse using the clip.
  • Replace the blown fuse only with a fuse that, has the same amp rating.
  • Install the cover.

Fuse color identification



Do not repair fuses and never replace a blown fuse with one that has a higher amp rating.

This can cause damage to the electrical system and increases the risk of fire.


If a new fuse burns out again shortly after you have installed it, have the electrical system checked as soon as possible by an authorized Audi dealer or authorized Audi Service Facility.


Some of the equipment listed in the following tables applies only to certain model versions or certain optional equipment.
