My MB 350E 4matic wagon has a red error code with an image of a battery and the message "visit workshop." It
also flashed Service E. What does this mean?
The battery light and visit workshop means one or both of your batteries are bad. Check this link for more details. ....http://mercedesforum.com/forum/mercedes-e-class-9/visit-workshop-message-red-battery-icon-34373/.....I'm not sure of the Service E. Maybe someone else can help.
Service E is part of a regularly scheduled maintenance.
