'03 C230 Kompressor
 

only 92k miles on this thing. Started actung crazy. losing power and was told to changevoltage regulator. had it done and absolutely did noting to solve the problem. Shop is telling me after diagnostic hook up that it is the alternator. OEM part and labor is running me $915. I guess htis is possible, but others have these issues with only 92k miles. Starting tothink I shoul have stuck with y infiniti but I liked the additional back seat room on this
