A used OEM Audi Horn - Low Tone / Frequency, part number 8E0951221C, also replaces 8E0951221A. This is the lower-pitched horn in a dual-horn setup, producing a deeper sound than the high-tone counterpart. When the low-tone horn fails, the vehicle's warning sound becomes noticeably higher-pitched or weaker, often indicating the need for this specific replacement.
