How to check and replace a faulty horn on Volkswagen Passat?

Take out the cover of the under-dash fuse/relay box and inspect the relay. Check the horn fuse 40 (25A) in the fuse panel at the left end of the instrument panel. Lift the car and place it on jack-stands. Unhook the electrical connectors of the horns that are in the front fender well, just behind the front bumper cover that can be reached under the vehicle. Test with a voltmeter to verify that there is battery voltage at the voltage supply wire terminal to the horns, press the horn button on, and have an assistant pressure the horn button. Should the relay be operating and there exists no voltage at the horn then the wire to the relay has fault. Measure the resistance between the wiring connector brown wire and a good ground using an ohmmeter and this should be less than 5.0 ohms; otherwise, fix the fault in the ground circuit. When the horn has some voltage and wiring circuits are in place, then the horn is defective and requires replacement. To change, one must disconnect the electrical connectors, remove the mounting bolts and remove the horns and install the new horns by following the same steps.

Volkswagen Passat Horn

The Passat Horn of the Volkswagen car is the audible protector, and as such, the driver can immediately declare their arrival and avoid a crash. Behind the front grille, it operates on a quick electric pulse and is connected to the steering wheel button to a vibrating metal diaphragm that sends a loud warning signal. The initial generation applied a single electromechanical low-frequency unit, which made a deep honk, whereas subsequent Volkswagen models applied smaller high-frequency discs, which created a brighter beep; the newer Volkswagen models combined both beep sounds to create a two-note chord that could be heard much more easily in the noise of the city. Irrespective of the version, the device meets legal sound standards as additional motorists, cyclists, and pedestrians get valuable seconds to respond when dangers emerge. The low-note Horn will not be as prevalent in production as it applied to be a few years ago, but dual-note arrangements are now carrying the day, as the blended pitch is transferred over a greater distance without additional volume. When a Horn fails, diagnosis typically starts with the fuse or relay before investigating the possibility of rusted connectors or a rusted diaphragm, and fixing is easily accomplished with just a few tools and a few minutes' work, as the plug design applied by Volkswagen models is consistent enough that a driver can have all the sonic safety restored to a Passat in a few minutes with only a little inconvenience.
