Audi TT 2005 - IDENTIFICATION
WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting any repairs involving steering column, instrument panel or related components, see AIRBAG SAFETY PRECAUTIONS in BODY INTERIOR article.
CAUTION: Before disconnecting battery, get radio code from customer. When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle.
Audi TT 2005 - ENGINE CODE
NOTE: Information for the 3.2L VR6 is included in this article. The 3.2L VR6 models use the Quattro? drive system and the Direct Shift Gearbox (DSG).
Engines are identified by a 3-letter code stamped on the engine. For engine code locations, see Fig. 1 and Fig. 2 . Engine codes are also located on the vehicle data plate.

Audi TT 2005 - 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 cause a fire.
For access to fuse box, refer to illustration below.
Fig. 3: Audi TT 2005 - Component Locations - Identifying Fuses Box Panel Cover
The individual circuits are protected by fuses. The fuse panel with the fuses is located on the left end face of the instrument panel behind a cover, other fuses and relays are located through out the vehicle for these components refer to COMPONENT IDENTIFICATION.
There is a plastic clip (fuse puller) in the holder of the fuse panel, which can be used to remove the fuses.
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:
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.
Audi TT 2005 - 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 TT 2005 - 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. 3.
- 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 (fuse puller) provided. The clip is located on the holder in the fuse box.
- Replace a blown fuse (recognizable by the melted metal strip inside) with a fuse of the same amperage.
- Firmly snap the fuse cover back onto the end of instrument panel face.
