All you have to do is replace the voltage converter module (PN: 2059053414). You can do it yourself. If you google W205 voltage converter replacement or W205 Auxiliary Battery Malfunction, you'll find documentation on how to do it. The part cost me about $140 with tax and the core charge. If you return the bad part, you'll be refunded the core charge of $15-20.
