thanx to all who responded,one of the first things i learned the the c43amg does have 4 02 sensors ,new computor came today over a week without,low and behold the check engine lite went out ,was disappointed after the maf sensor change and nothing emediate,i rarely drive the c43 as i am fortunate in that i get to drive company worktruck,after i posted the next drive lite went out ,i have other issues with it wipers only work at hi speed pos,suspension noise in right front ,was supposedly stuck in ditch ,but im thinking worse than that,all who post are awesome thanx for the info.
AMG there is no substitude
