The individual circuits are protected by fuses. The fuse panels with the fuses are located on the left and right
front faces of the instrument panel behind a cover and in the right storage area in the luggage compartment.

There is a plastic clip (fuse puller 'A') in the cover on the left side of the instrument panel, which can be used to

remove the fuses. The crank (B) is used for emergency operation of the power roof (if equipped). You will also
find a label (C) on both covers in the instrument panel with the fuse layout) for the corresponding fuse panel.
Refer to Fig. 30.

Two spare fuses and a sticker identifying the fuses are located on the inside of the fuse box cover.

Fuses with the proper ampere ratings are available at your Audi dealer.

NOTE: On no account should fuses be repaired (e.g. with tin foil or wire) as this
may cause serious damage elsewhere in the electrical circuit or cause a
fire.
If a fuse blows repeatedly, do not keep replacing it. Track and fix shorted
or overloaded circuit.

AUTOMATIC CIRCUIT BREAKERS:

The electric power windows and the electric seat adjusters are protected with Circuit breakers which reset
automatically after the circuit overload has been corrected.

FUSE - COLOR CODES

Identifying fuse color and ampere rating, refer to table below.

WARNING: Never replace a fuse with one that has a higher amperage rating. A fuse
with a too high amperage could damage the electrical part and cause a
fire.

Switch off the ignition and the electrical component affected.


Carefully pry the face cover off the instrument panel using the ignition key or a screwdriver. See Fig. 29.
Check the fuse index to find out which fuse belongs to the component which has failed. See FUSE
INDEX INFORMATION.
Remove the blown fuse with the plastic clip provided. The clip is located on the holder in the fuse box
cover.
Replace a blown fuse (recognizable by the melted metal strip inside) with a fuse of the same amperage.
Firmly snap the cover back onto the instrument panel face.
