2014s shifting into Reverse
I noticed this by accident.
I had my car in D reach over to the glove was rolling at the time no gas and I hit the gear selector and the car went into reverse.
I then check, in D no gas no brakes I can push the selector into R. No lockout safety of the brakes is needed.
I thought you needed to be on the brakes to go from D to R or is something wrong with my car.
I also noticed that I can stop the car very light brake pressure where my brake lights are off.

MBWorld Fanatic!
Damn! I hope this is NOT possible when one is going at 50mph! Not that I like the idea of this being possible at any speed when the car is already in motion one way or another.
As for the brake light thing. Not that I have tried it in this car, but in my previous cars, I did notice that such thing is possible (engagement of the brakes without brake lights coming on... enough to stop car from rolling)

Your brake sensor behind the pedal seems bad; time for a new one

Thank You Peter
Would that switch also be why I am able to enter R from drive without being on the brakes.
I am going to try this on a 2014 E550 if I have the same result.

If it were going into park, I would say a bad door pin

my Thought is that at some speed, perhaps over 10 miles an hour the energy of forward motion is enough to just snap the reverse gear like a twig so as to keep the car continuously in motion. Therefore the reverse gear at that speed is unlikely to be beneficial.

R lock
You dont have to have on the brakes by design so its okay, see attachment explaining R Lock........Im currently not able to get in reverse after driving. Already put on a new shifter, which is referenced N15/5 on the attachment. Looking at getting new conductor plate to fix, possibly some speed sensors. Does anyone have experience with this??... P Lock works fine so its not brake related.
no; over 10mph or so there is a electronic lock out on most modern transmissions is my understanding ... someone correct me if I'm wrong on the 722.9
