Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** sounds like the alternator is the issue. It is very common and when it stops charging the battery light will come on. I would take the vehicle to have the alternator load tested. Most auto parts stores can test this for you. it can also be a programming issue, but that is not as common. I hope this helps. Please let me know if you need anything else.
