Not sure about the codes through personal experience. However, I spoke to Clint at Bar Tuning here is Houston and he told me that there should be no issue with codes and that the process is pretty straight forward. On my 2012 the battery is located in the trunk under spare as well. On another note... why can I not find anything about battery replacement on any of the Audi forums or the net? It seems kind of weird...do A7 owners not do any of their own maintenance? Just wondering.

I was told my my dealer that they would have to reset codes when replacing the battery on my 2012 A7. With the cost of battery and labour, they estimated the bill to be around $500! This seems a bit outrageous. As mentioned in this post, there is little in the owners manual referencing battery replacement. Has anyone else been told this by Audi dealers as well?

I asked Hans, the owner of the local VW/Audi/Mercedes garage about this a while ago. He does the replacement by connecting a fully charged battery to the battery posts under the hood with a set of booster cables (the car is not running). He then disconnects the old battery in the trunk, installs and connects the new battery and disconnects the booster cable. That way the car does not power down and everything stays normal, no settings need to be done.
