A used OEM Audi Horn (Low Tone / Frequency) with part number 4G0951221. This low-tone horn produces the deeper, bassier note in a dual-horn setup, often paired with a high-tone counterpart for a full, authoritative sound. When the low-frequency horn fails, the vehicle's warning tone may sound thin, weak, or missing entirely. This genuine unit was removed from a donor Audi and is ready for installation.
