Reprogramming after battery change

What is your question?

I am having an issue with a audi battery that is a little more then a year old. I was told that it may need reprogrammed. I am not sure if this is true or if it applies to a 2001.

What makes this problem better or worse?

if the car sits it looses power

How long has your 2001 Audi A6 Quattro had this problem?

a month
