This is a used genuine OEM Horn - Low Tone / Frequency, part number 8E0951221A, originally removed from a donor Audi. It also replaces the superseded number 8E0951221C. Mounted on the right side of the vehicle, this low-tone horn produces the deeper, bassier sound of a dual-horn setup. If your car's horn sounds weak or only emits a high-pitched note, a failed low-frequency horn is often the cause, as it stops working while the other horn continues.
