Save yourself significant time, money, and angst by purchasing a good scanner to diagnose yourself (the car). I use dedicated Merc iCarsoft. @ $150.

I don't think that type of scanner would be able to tell me whether my auxiliary battery relay or the battery control module is bad.

A good scanner will give you codes, voltage, and point to your problem. But if you have deep pockets, the dealer will be happy.
