What you will need
Mercedes bumper parking sensors are interchangeable between models.
The same sensor is used on multiple models, including C S E CLK SLK CL M ML G GL R Class. Always verify compatibility with an auto parts seller or dealer.
New Mercedes parking sensors typically do not come painted. Therefore the new sensor will not match the paint of your bumper and car.
Getting the new parking sensor to match the color of your car is easy. You will need to get a custom mixed spray can that matches the color of your Mercedes-Benz.
You need the paint color code of your Mercedes-Benz. Mercedes paint code can be found on the sticker on the driver's door. It is on the right side of the label. It will end with three numbers. For example, 744, which is commonly silver, or 040 for black.
Replacing the parking sensor on a Mercedes-Benz is very easy. In this guide, we will show you how to replace a Mercedes parking sensor and how to paint the new sensor to match your car's color.
- Purchase/collect a new Mercedes parking sensor. It can be 'used' or 'new.' Make sure to match the part number. No coding will be needed.
- Sand down the paint from the sensor. If the sensor is not painted, scuff the surface with 500 grit sandpaper.
- Spray a light coat on the sensor and let it dry for at least fifteen minutes. Apply a second coat of paint. If you are using single-stage paint, it will contain clear as well. But if you would like to have the sensor look as close to the original bumper, you can apply a coat of Automotive Clear Coat.
- Determine the faulty or missing parking sensor. It's hard to miss it.
- You will need to access the sensor from under the bumper. In some cases, you may even need to remove the bumper.
- Unclip or remove any bolts that hold the bumper in place. Mercedes-Benz uses plastic retainers and 10mm bolts, but Torx head bolts are used in some models.
- Reach to the back of the bumper and remove the sensor by pressing the two locking tabs.
- Press the new sensor into place, and plug in the electrical connector.
Mercedes parking sensors can fail, causing part of the system not to work properly. Failure is either due to an accident, or the sensor may stop working if water gets inside it.
You can also remove the sensor and try to dry it, but it doesn't always work. Replacement sensors are straightforward to work with. New sensors can be bought online for $20-$30.
