My battery light has come on in the E320 2004 model Mercedes. What can I do before I take it to the shop that might turn the service light off?
Optional Information: 2004 Mercedes-Benz E320 3.2Already Tried: The red malfuction light is on with the battery light. What is the problem?
Hi!The red light that you are seeing is a charging system malfunction indicator. This light will come on when there is a problem with the charging system, and your alternator is not charging your battery. In most cases, the alternator is bad when this light comes on. In a few instances, a wiring or a fuse problem will cause the light to illuminate. I would recommend having your charging system checked for problems. If the car still starts fine, then the battery is probably not the problem.Let me know if you have any more questions!
