What's wrong?
The underbody sensor connector on 2012-2014 Volkswagen Passat TDI vehicles is part of the electrical wiring that lets a sensor under the car send signals back to the vehicle's control systems. Small wire seals inside the connector are supposed to sit tightly around the wires. Their job is simple: keep water out of the electrical terminals.
On affected Passats, those seals were not seated correctly during assembly. Water can get into the connector and reach the metal terminals. Over time, corrosion builds up, electrical contact becomes poor, and the connector can short. Volkswagen's review tied the problem to overheated electrical connectors and isolated underbody fires.
Before a failure, the main warning sign is the MIL, or malfunction indicator light, on the dash. It can turn on when corrosion causes improper electrical contact at the sensor connector. Treat that light as a reason to have the recall checked, even if the car still drives normally.
