MB W212 model year 2012 DO NOT HAVE auxiliary battery. Only ONE big old 12v battery (front passenger side, close to the firewall). Alternator may be your problem. Until model year 2014 > up (with stop & start in traffic that need an auxiliary battery). I can not locate any 2nd in my car, my mechanic told me my car had ONLY 1 battery.

No code for anything else? You have 6 coils and now you need to find the bad one.
