I have a 2002 S500 which has a battery drain issue if left overnight. Drivers side mirror signaled a problem, then the alarm would start going off. Dealer replaced the alarm but the car continues to drain. New battery in July.....it reads in good shape. Once jumped warning indicator of drivers side mirror signal and airmatic come and go. Now the zenon drivers side front lamp is out. At dealer for 2 weeks......they have no clue at this point.

Welcome to the forum, Johnrs. One of the first things to become familiar with here is the W220 S-Class Encyclopedia in the "stickies," the blue-backgrounded area at the top of the main W220 forum page. That's why the title of that sticky says "Start Here."
In the Encyclopedia you will find links to threads dealing with quiescent battery drain. You will also find information on jump starting (if do it wrong, you can damage electronics), and on headlight problems.
Good luck.
