Checked from the dash, battery seems ok, 12.8V when engine off; 14.3+ when engine running.
Then after a while of engine running, get 4 Malfunctions (see pics):
  1. Light sensor, drive to workshop
  2. BAS not active...
  3. ABS not active...
  4. ESP not active...
Any suggestions if this is the battery going bad, or alternator, or something else?
Thank you.

Hmm...that looks very similar to when I've disconnected the battery on either the W220's or the W211. In my cars, when I've driven the car about 50 metres (yards) or so, those BAS/ABS/ESP messages go away, because the computer grabs the ABS sensor information again. Could it be that the battery terminals are getting corroded?

Thanks Cowboy. Yep, the car won’t start this morning so it probably was the battery. I’ll call Mercedes and have them come over and replace. I’ll keep you guys posted.

Battery replaced.
I called roadside assistance. Mercedes sent a guy out and for $200 bucks I think I got my moneys worth. My last battery according to my receipts was
7 years, 8 months, 4 days ago- Jan 2012. Not bad.
