Where is the hood ajar sensor located on a Audi A4 2002?

On a 2002 Audi A4, the hood ajar sensor is typically located on the hood latch assembly. It's usually a small switch that is triggered when the hood is closed, sending a signal to the vehicle's electrical system. If you're looking to inspect or replace it, you'll need to access the latch mechanism, which is generally found near the center of the front of the car, just below the hood. Make sure to check the wiring and connections for any issues as well.
