A search in the 211 AMG forum may help.

Could be the battery control module. Post this in the W211 AMG section for more help.

thanks i will. i think i know whats going no.. from cold the battery reads 14 . when the car warm it reads 11.5.. the alternator could be breaking down when its hotter ....? or would the battery control module do this. ?
