I would suggest you scroll down the main forum page and find the W211 section of the forum where members own W211s and will be more than glad to help you. You've posted in the section for a new MB EV that's not on sale yet.

Why is your main battery not able to charge under 14.1V alternator...

it may have a defective cell so it does not appear to hold charge.

it maybe the alternator output voltage ends up below 12.6v into discharge territory. Don't assume charge voltage stays at 14.1v
