This Audi Horn – Low Tone (OEM 4E0951221B) is a used genuine unit from a donor vehicle. Also known as the low-frequency horn, it produces the deeper sound in a dual-horn setup. A common failure is the horn not sounding or sounding weak due to internal corrosion or diaphragm wear. This part supersedes 4E0951209F.
