DIY Instructions: How to change brake stop light switch on a Mercedes-Benz
Step 1. Locate brake light stop switch
The brake light switch is located right above the brake pedal. To access it, remove the underside panel cover. Usually, the panel is held in place with 3 to 5 screws. Mercedes-Benz uses Torx head screws. You will need a Torx set such as this T-Handle Star Set. Some of the older Mercedes-Benz cars used Philips screws so check before you order a star screwdriver set.
Step 2. Remove panel
Once you remove all the screws, now you are ready to pull down the under side panel. In most models you don’t need to completely remove it, just pull it down so that you can access the brakelight switch.
Step 3. Remove the brake switch.
The brake light switch is located right above the brake pedal. It could be either on the front or the back of the pedal. In the W211 E-Class, it is on the front. In the older W210 E-Class, it is located in the back on the back of the pedal. You may need to lay on your back to access the switch. To remove the switch, press on the locking tab and then rotate it clockwise.
Step 4. Install new switch
Once you remove the old brake light switch, unplug the electrical wires from it. Plug the wires in the new switch and install the new switch by twisting it counter-clockwise. Watch the following video on how to install brake stop light switch on an Mercedes-Benz E-Class .
Can’t get car out of park, is it the brake light switch?
While the shifter module itself could be the problem, it is most likely that the brake light switch needs to be replaced.
