Where is the horn on a 2008 passat? - 2008 Volkswagen Passat Sedan

you found the right place buddy.. i know a lot of websites for repairs and manuals that can really help u..
like reliable-store is pretty good

Use a voltmeter at the horn connector and have someone press the horn button. If you see voltage at the connector, then the horn is bad. If you don't see voltage, then either the relay is bad, the clockspring, or the horn button is bad

BEHIND THE 2 FRONT BUMPER SIDE TRIMS

2 fuses located above relay panel. 1 is for flashing lights, the other is for the alarm horn.

if you want to disconnect the horn, the easiest way is to locate it under the hood and remove one of the wires connected to it.

Where i find a horn of the 2008 vw passat

1 fuse problem, 2 wires chek that first

Check the horn relay is ok,
Check the horn ground is ok.

Place a trouble light across the horn supply- when horn is pressed it should light up steady.
If it lights up, the voltage to the horn is ok -then a replacement horn should fix it.

I had the same problem. My 2008 Passat had to get a faulty rotator that controls the electrical part of the dashboard on the car.First the Air Fault light came on then my whole dashboard went out the next day. I had no horn, no radio, no lights on at all on the dashboard. It was that rotator part that controls the electrics. I was told they are faulty after a few months, they ordered a new one, installed and my car is good as new.
