It's really weird, but I cannot find the auxiliary battery. Under the passenger side mat, there's a fuse box, and a bix plastic thing right where the aux battery is on your photo. Someone else on the mercedes forum also had no battery, and a big plastic thing like mine. I thought maybe there's no battery in my W176 (2017 UK 180d model), but the mercedes dealer sold me the battery right. No idea what to do...
Just had a look on my own W176 (late 2017 UK 180 petrol, manual transmission, AMG line) and it sounds the same as yours... no auxiliary battery. They don't all have them. (great car though)
@@andrewsantana5204 hey andrew, are you able to see a red and black wire from the main loom which aren't connected to anything? Also may I know did this error occur after you took your car in for repair. For us, what happened was a mechanic for whatever reason couldn't be bothered to movee the aux battery cable from the main harness loom to where the battery normally goes, so we had to look for the aux battery cable through the main loom.
This aux battery is also affecting not showing the ECO start/stop function or only main battery? I have no errors on display only ECO never shows up since I bought W176..
