The first thing I'd check is whether your car was included in the voltage regulator recall. If so, the second thing I'd check is if the recall had been performed. Mine was, and it was.
If you have a volt meter you can check voltage at the battery while the car is running. If you see 12 volts, rather than 14, your regulator or your alternator may be toast.
The good news is, an OEM votage regulator is about $65 at the dealer ($80 without the MBCA discount). If the alternator is dead, those can be rebuilt for under $100.

Did you check with MB to see if your vin is flagged for the recall that Marcus mentioned? My MB tech said that the recall covers the voltage regulator and can sometimes be extended to the entire alternator as well. Seemed like an odd statement, but that's what he said. Maybe you can get compensated to a certain extent if it's part of the recall.
Let us know.
Thanks.
