If the car has front fog lamps, these are in the bumper casing below the headlamps.

The fog lamps are operated via a button in the light switch module (LSM). An LED in the button lights when the fog lamps are activated. The light switch transmits data via serial communication to the central electronic module (CEM). The lamps are powered via a directly connected relay on the central electronic module (CEM).

There are diagnostics for the fog lamp relay.
