Sounds like your battery is failing. How old is the battery? Anything over 4 years is suspect. You can have a load check performed but it must be done with the battery out of the circuit. W210's are pretty sensitive to slightly lower battery voltage which produces the problems you are having. If it is you can have MB (1-800-FOR MERCedes) come out and replace the battery and reset everything for about $175. That should qualify you for 18 mos. of Road Side Service.
