Where is the front reversing buzzer located on the Audi A8L?

[Kent]

Audi A8L's parking buzzer is located under the hood, on the left side of the engine compartment next to the battery. Composition of the reversing buzzer: The reversing buzzer mainly consists of a coil, contacts, capacitor, and the buzzer itself. Working principle of the reversing buzzer: It essentially controls the buzzer through a relay circuit. There are two sets of coils, L1 and L2, with the L2 coil circuit connected in series with a capacitor. When powered, the buzzer activates and produces sound. Both coils are energized simultaneously, but since the currents are equal and opposite in direction, their magnetic fluxes cancel each other out, causing the contacts to close. As the capacitor continues to charge, the voltage across it gradually increases, reducing the current in coil L2. This increases the magnetic flux in coil L1, which pulls down the contacts, interrupting the circuit and stopping the buzzer.
