Hello this is my first post and I own a 2007 c230 sport black w/ grey interior. I'd like to post a problem with my vehicle and try and acquire some answers that will help me solve the issue at hand. Hopefully, I will be forgiven if this is in the incorrect forum section or maybe an admin will help me out by moving this thread into the right spot. I haven't owned this car 6 months and about a month ago I started receiving the big red picture of a battery on my instrument cluster intermittently. I have been lazy and not looked into it. I also just moved up from Houston and started a new job this month so that may have played some part. I was driving in the light rain today and was running all types of loads: windows, sunroof, a/c, wipers, radio, fog lights and while I was in the bank drive thru today when I felt a surge of power loss. Motor did not die. But, I was now in what I would think is safe mode. My ABS light was now on and on my instrument cluster it put out a message saying that my ESP, ABS and some other electronics were disabled. The a/c blower motor wasn't putting out any air in any setting, the radio wouldn't turn on, and sunroof wouldn't work. I couldn't get out of which ever low gear I was in. This is why I was thinking I was in a sort of safe mode. I stopped at the local part shop and turned off the motor and it wouldnt start and I put a meter across my battery. 10 volts so I blindly put in another battery. Car starts up and battery light is back on in a few seconds but all electronics now work so I rush to my destination. Curious I put the meter across the battery and it reads 12.1 volts. Start it and with the meter on and motor running it is 11.9 volts. Motor off again and its 12.10 volts. Motor on 11.9 sometimes 11.8. After I left the parts store I've driven it about 45 miles with a few stops in-between. Alternator? Voltage Regulator? Belt? I haven't checked these out. My sunroof is the only thing still acting screwy. The switch for tilt roof close makes it open instead of close. Anyone with similar issues or advice? Thanks a lot in advance.

Welcome to Benzworld, your alternator is not putting out enough current.
