After having fixed RCM I drove car for 10 minutes to warm up. I let car sit in driveway idling after 15 minutes car shut off! same problem would not start. so I guess the fix I did, did not work,

called mercedes and parts guy said modules are a common thing, he also suggested that maybe the CRANK SENSOR IS THE PROBLEM,

leaving on a cruise tomorrow, will worry about it when I get back
