Hi, mi c300 2008 can’t turn off esp. Says Esp Inoperative and cruise control also is inoperative. Mirrors won’t fold by button nor by key. I already tried enabling them.

 

What does your MB-specific code reader say?

 

In the past when I have had this happen randomly, I replaced BOTH batteries in my car. You may have only one battery. How old is it or are they?

Mercedes are very temperamental when it comes to operating voltages.
