If the horn on your Audi TT isn't working, first check the fuse associated with the horn in the fuse box, as a blown fuse is a common issue. Next, inspect the horn itself for any loose connections or damage. If those components are functioning properly, the problem may lie in the steering wheel switch or the wiring. If you're unable to identify the issue, it may be best to consult a professional mechanic for further diagnosis.
