first VAG scan...some questions

**gqambitions** · 06-28-2016 09:31 AM

A brief synopsis of the situation. My battery failed the "test" at an Audi dealership. I took it there to have a used car inspection done after I recently bought it. The car dealership I purchased it at replaced the battery and then this fault code comes up when I have a friend run a scan for me. what do these codes mean please? Upon looking at a couple of forum discussions hear I see it could be an issue with the a/c temp controls, or something along those lines. My a/c is very hot when I first turn it on but then it cools really well after a couple of minutes. Also noticed a loud sound when it is turned on from engine bay, nothing alarming, but it is just noticeable. I assume this is regular or maybe not. I came from a 2015 Acura TLX , so I understand that this is a 2010 Audi S5,and maybe some things I hear now than with my 2.4l Acura. For the battery coding I am thinking maybe they did not program it to the car? any advice would be helpful, thanks.

I would go to a measuring block and look at your battery voltage. Maybe try ensuring everything is tightened in the trunk? Cable loose, bad battery or bad alternator.

If the battery is original, I'd say it the likely culprit.

ok, I will try that out. Dealership I bought it from will be taking a look at it as well. Thank you.
