Review on maXpeedingrods 2059053414 2054400073 Voltage Converter Module: Enhance Your Mercedes-Benz C-Class CLS350 W205 W253 S450 2013-2018! by Evan Larson

Mercedes have a number of backup systems including a backup battery which helps power all electronics and is prone to burn out. I have a 2015 C300 with 50,000 miles and mine is gone. Ordered online and arrived within a week. There are a few Youtube videos that provide good installation instructions. Be careful when pulling back the passenger footbed. After installation, the error code disappeared. 3 months have passed and the problem is solved.
