What are the symptoms of a faulty seat occupancy sensor in a 2013 VW Beetle?

A common symptom of a faulty seat occupancy sensor in a 2013 VW Beetle is the airbag light staying on regardless of whether someone is sitting in the passenger seat, or the light coming on only when someone is seated. This sensor tells the control module whether to deploy the passenger airbag. If it fails, the system may incorrectly assume no one is in the seat or that there's a fault in that circuit.
