A used OEM Audi low-tone horn (OEM 4D0951221A) is the right-side unit for models including the A6, A6 Quattro, A8, A8 Quattro, and Allroad Quattro with 2.7L–4.2L engines. Also known as a low-frequency horn, it produces the deeper note in a dual-horn setup. If your horn sounds weak or doesn't honk at all when you press the steering wheel, this component may be the culprit.
