Some reason the parking brake light came on and wouldn’t go back off until I did what I mentioned above.
The mechanics like using the computer tablet thing that I’m not sure what it’s called. I had to go to three different mechanics until one of them had an up to date tablet to disengage the parking brake. I told them about the way to do it shown on the YouTube video, but they insisted of using the computer. I think that’s what messed it up once the rear brake pads were replaced. Lucky I was able to fix it. I definitely recommend taking to the official Mercedes dealer if your is 2015 and up and can’t figure it out.
Do do you get any messages on your dash when you start the car? Also, do you have the parking brake on when you’re trying to do it?
1. Turn the ignition to Position 1.
1.1 Release the parking brake, if it is active
2. Make sure the mileage is displayed in the dash center window
3. Don't wait very long before accomplishing the next step: Push the far right "telephone accept call" button on the steering wheel, then push the "OK" button on the left and hold both down for 5 seconds or so.
4. The workshop menu should appear.
5. Scroll down to "Pad replacement" and push OK.
6. Choose OK for "Moving to fitting position"
