Hi, welcome to Just Answer. My name is***** problem is caused by either low battery voltage or a fault with the electronic ignition switch or with the front signal acquisition module (SAM). You will need to get the car connected to a Mercedes diagnostic tester to read out the fault codes in the engine control module and the front SAM. The fault codes will point to the problem. Based on your description I suspect that either the front SAM or the ignition switch is malfunctioning.
Let me know if you have any questions.
