W210 E430 2002

OK, the battery was weak, so I purchased a new one.

With battery out of car for about an hour, I replaced it with a new battery.

Now the dashboard is telling me that with BAS, I need to go to workshop.

What workshop is it talking about?

What could I have done that would not have raised this error message?

Many thanks
