Fuse Panel Location
The fuses are arranged in one centralized unit. The fuse/relay box is located under engine hood, on left side in water drain tray and is protected by a cover. In addition to fuse/relay panel, some of the newer models are equipped with auxiliary relay panels.
CAUTION:
Use extreme care when trouble shooting electrical system. Relay locations are subject to change and may vary from vehicle to vehicle depending on options. If in doubt, consult an Audi dealer before replacing any relay.
