I have an issue with my MFD not turning off and draining my battery on my 2006 Mercedes C230. I have replaced the battery and still nothing seems to make the MFD go into a sleep mode when the car is turned off. I have two messages that are present but I don’t think they are an issue. I have an SRS warning message and the driver’s mirror turn light bulb is out and I am getting a message for that. Any thoughts?
