E300 auxiliary battery malfunction

Hello all MB fans,
I tried to find solution of m problem in similar topics, where E350 CLS and others were described, but I think construction of my car is slightly different. About 3 weeks ago I have bought english version (right hand drive) of E300 hybrid, 2013 (after facelift) and practically since beginning it shows ''Auxiliary battery malfunction'' communicate on the dashboard. What I've found on internet is quite confusin as people describe so many different versions of models, engines, additionl stuff (like start&stop - I don't have it in my MB). Could somebody please tell me where I can find this battery and how bad is it to replace it for such not experienced person like me. Thanks in advance.

If you do not have start/stop function (ECO) most likely it is the backup battery for transmission selector. Post VIN I will confirm.
