In a Mercedes-Benz C230, the trunk light sensor is typically located near the trunk lid, often integrated into the latch mechanism or the trunk itself. It is designed to activate the trunk light when the trunk is opened. If you're having issues with the trunk light, checking the sensor's wiring and connection can help diagnose any problems. Always refer to the vehicle's manual for specific details related to your model year.
