WARNING:
Vehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, refer to appropriate AIRBAG SAFETY PRECAUTIONS or SAFETY REQUIREMENTS FOR AIRBAGS in BODY INTERIOR article.
Engines are identified by a 3-letter code stamped on the engine. For engine code locations, see Fig. 1-Fig. 2 . Engine codes are also located on the vehicle data plate.

Some of the equipment items listed are optional or only available on certain model configurations.
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.
NOTE:
Whenever replacing a fuse, always consult the sticker on the inside of the fuse panel cover. It contains the most up-to-date information regarding the fuse arrangement.
For fuse and relay positions within the panel, see Fig. 7.
For relay number, position number and circuits protected, see the appropriate IDENTIFYING RELAYS table.
For fuse number, position number, amperage rating and circuits protected, see the appropriate IDENTIFYING FUSES table.
NOTE:
The relay panel (4 position) carrier is located in electronics box, plenum chamber, in the left rear corner of the engine compartment.

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.
For access to fuse box, refer to Fig. 6.
Fig. 17: Identifying Fuses Box Panel Cover

A problem in the electrical system may be caused by a blown fuse.
The various electrical circuits are protected by fuses. The fuses are clustered in a centralized unit. The unit is located behind the face panel at the end of the instrument panel. The crank for operating the sunroof in case of a power failure is also stored behind the face panel (If equipped with sunroof).
Two spare fuses end a sticker identifying the fuses are located on the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle. Fuses with the proper ampere ratings are available at your Audi dealer.
NOTE:
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.
