Alternator message on C230K
Used original equipment Bosh, rebuilt. Part was 335 UD plus 150 labor vs 1100 at dealer dor alt plus 1200 labor. Battery check indicated batt. was all right..
However computer warning , red light indicator of alternator or Battery failure does not turn off.
Do I need to take car to the dealer to clean up message and pay 300 bucks?
Does it actually do anything to keep warning on?
Thanks in advance to the experts-.
