B1F4500 error code

[bida1982]

Hi , I have run a diagnostic on my Mercedes A Class 2019 AMG W177 and I’m getting the following fault codes (see attached photo below ) which I can't clear. I replaced Auxiliary battery but that didn't help. Anybody got any idea what the issue is and how to resolve it, please?

You changed the wrong battery....

You changed the wrong battery....

so do you think if I change the main battery problem will be resolved?

I don't have a problem with starting the car. some of the error codes I was able to clear after changing the Auxiliary battery but 5 I can't clear, and I was wondering if anybody has any idea what the issue is and how to resolve it.
I can buy a new main battery if you think the old one is the cause of the errors?

My main battery seemed fine no issues at all except for S/S.
All your codes say "Starter Battery" so that is the one to change.
