you will need to tow the car to a local MB specialty shop.
they will have the correct software to diagnose this.
I checked battery with local mechanic and it was good on test. However decided to put in new battery and everything has quieted down ,however, may have to reset to clear computer exception. Although old battery tested 12 volt charge there may have been something else in battery condition causing it. It was like being in and driving a haunted car.. you nid not know when something would work or not work. Boy am I glad that is over. All I need is for electric trunk to work and fuel gauge also.
