Original BMW Parts carry a 24-month parts warranty.

For 2012–2018 BMW 3 Series, 4 Series, ActiveHybrid 3, M3, and M4 owners, this Original BMW horn is the factory audible warning device for these cars. A horn uses an electrically driven diaphragm to produce its tone and sounds when the driver presses the horn pad on the steering wheel. BMW parts data cross-references this part with the number 61-33-7-300-975, which helps when you are matching the part to a dealer invoice or an old part on the car.

Coverage runs across the sedan, xDrive, Gran Turismo, coupe, and Gran Coupe body styles of the 3 and 4 Series, plus the diesel 328d and the ActiveHybrid 3. This is a factory BMW part.
