Hello, i have personally ran into this before, you have a communication error in the car, there is a shorted wire that is causing the communication system between modules to crash. the one i had , the wire for the passenger front seat was shorted to the frame and i was able to reproduce the issue by pressing on the seat back where the right shoulder area would be, that does not mean that yours will have the exact same issue , it can be the drivers seat as well, but this was a known issue with a bulletin. this will be very difficult to diagnose without a mercedes scan tool and the knowledge of the can data bus, i suggest a dealer since there have also been few after market independent shops that seem knowledgeable with the can system. hope this info helps, let me know if there is anything else i can assist with, Please take a second and click the stars at the top of the screen to rate me so i may receive my credit , 5 stars is ideal , please request me in the future.
Keep in mind then when you rate it does not end our conversation. you can still return here to me for follow up information if needed, Lou P.
