Stuck on a backroad.
Expert:  Lou P. master tech replied 2 years ago.

Hello. When you have that error on the dash that says "display defective " that means that there is a communication issue in the car and the only way to tell what is going on is with a scan tool. There will be nothing that we can do to get this going. I know this is not that answer you want to hear and I apologize but the car needs towed to a dealer or a repair facility that has good German car experience and a Mercedes type scan tool. Again my apologies. Hope this information helps clear Up what you are seeing. The car will not start as long as the communication system is down. It's the computer networks internal to the car and there is no fuse or quick check to perform. Lou

I was able tonshift the car in neutral. Now I cant, how will I tow it
Expert:  Lou P. master tech replied 2 years ago.

Ok the S class is the only model that has no emergency release. but try this , turn the key on and press the brake and tell me if you can feel the slight clicking on the shifter everytime you press the brake ?

Expert:  Lou P. master tech replied 2 years ago.

There is a trick to getting it out with some force but can be tricky if you can't feel the click.

Customer: replied 2 years ago.
No clicking
Expert:  Lou P. master tech replied 2 years ago.

Ok that's what I thought. The brake switch is part of the communication system :(

Customer: replied 2 years ago.
how does it tow?
Expert:  Lou P. master tech replied 2 years ago.

Ok if you pull back gently on the shifter just before you feel the stop, then bang on the top of the shifter as you pull back it will jounce the shifter lock and allow the shifter to be pulled back.

Expert:  Lou P. master tech replied 2 years ago.

Tow trucks should always use a flatbed with a Mercedes. They can drag the car up the ramp by greasing the tires

Customer: replied 2 years ago.
Ok. And no way to get back to limp mode?
Expert:  Lou P. master tech replied 2 years ago.

It won't hurt anything. Worst case if we can't get the shifter loose

Expert:  Lou P. master tech replied 2 years ago.

Well limp mode is decided by the car there is no setting

Expert:  Lou P. master tech replied 2 years ago.

It was sheer luck you had a chance to get it going before

Expert:  Lou P. master tech replied 2 years ago.

Also turn the key on and off and on and off and keep pressing the brake to see if you'll get lucky to get the shifter out

Expert:  Lou P. master tech replied 2 years ago.

Take the key out and lock the car and then unlock and try again to see if the car will quickly reset before it notices the system has a fault

Customer: replied 2 years ago.
Ok that worked. Also I have no error message, but still no turning iver
Customer: replied 2 years ago.
Pics of cluster
Expert:  Lou P. master tech replied 2 years ago.

Ok then leave it in neutral!

Expert:  Lou P. master tech replied 2 years ago.

Ok so it does not crank ? The starter does not turn ?

Expert:  Lou P. master tech replied 2 years ago.

I can tell there is still a issue because the gear indicator where the clock is at does not show what gear it is in

Expert:  Lou P. master tech replied 2 years ago.

So at this point it will need to be towed. If by the miracle it starts to work again I still say drive right to a shop as there is something going on and it can fail again at any time. Sorry I didn't have a quick fix but the communication system is not something we can diagnosis over the Internet.
