Audi A3 2007 - COMPONENT IDENTIFICATION FUSES - CIRCUIT PROTECTION

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 possible cause a fire.

For access to instrument panel fuse box, refer to illustration below.

Fig. 19: Audi A3 2007 - Component Locations - Identifying Instrument Panel Left Side Fuse Box Panel Cover

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

There is a plastic clip (fuse puller) in the cover on the left side of the instrument panel, which can be used to remove the fuses. The crank handle is used for emergency operation of the power roof (if equipped).

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. Proceed to diagnose and fix shorted or overloaded circuit.

AUTOMATIC CIRCUIT BREAKERS:

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

Audi A3 2007 - 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.

Audi A3 2007 - Replacing A Fuse

A problem in the electrical system may be caused by a blown fuse.

• 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. 19.
• 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.
