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.
The sensor light for the trunk may stay on when the trunk is closed due to a malfunction in the trunk latch or sensor, which may not be properly detecting that the trunk is securely closed. Additionally, a wiring issue or a blown fuse could cause the light to remain illuminated. It's also possible that dirt or debris is obstructing the sensor, leading to incorrect readings. Checking the latch and sensor for proper function and cleanliness is a good first step in troubleshooting this issue.
With the key?
in the trunk
Depends on the year model. In my 2005 c230 sedan, it's in the trunk. Looking into the trunk from the rear of the vehicle, it's on the right side, behind the liner.
All Mercedes have battery in the trunk
It may be due to a bad alternator. If the alternator has a bad diode it will draw battery power when the car is off. Another possible draw is the trunk light. The trunk light works with a sensor that is mounted to the curved bar on the left side (drivers side) of the trunk. This sensor sometimes slides out of adjustment and keeps the trunk light on when the trunk is closed.
To replace the middle brake light on a C230 Mercedes, start by opening the trunk and removing any covers or trim pieces that obscure the light assembly. Unscrew the brake light housing, then gently pull it out to access the bulb. Replace the old bulb with a new one, ensuring it's securely fitted, and reassemble everything by reversing the removal steps. Finally, test the light to ensure it functions properly before closing the trunk.
go to napa and buy the sensor for about $11.00.
They are located inside the trunk lid, underneath the felt lining. You need to unsnap and pull back the felt lining to access the bulbs for the license plate light.
