Mercedes me connect: Battery Monitor – Charge Status Critical
Wondering if it ahould be hooked up to the starter battery as well, though I've no idea where it's located and google did not help me.
Anyone else getting this?
12 Volt Auxillary Battery for C Class 350e Hybrid Sport
This is on the passenger side below the glove box, to access it, you will have to remove the grille below the glove box, the carpet and a couple of plastic panels.
You then take off the plastic foot guard covering the battery.
Once I replaced the Auxillary battery all fault codes corrected themselves and everything is now working correctly. The battery replacement is available from many forum sponsors and online.
