Replacing battery and code change
Three years ago, I replaced the battery on 2012 A6 with a battery that I purchased from Costco. I have no way to put the new battery code into the car memory and hence didn't bother with it. The battery and the car have been running fine without any issues. I actually checked the charging voltage during charging and at full charge. I saw no difference in voltage regardless of the battery status.
There are talks on Youtube about battery damage if not updating the code after replacement. I suspect this is just a way to get you to pay dealer $450 for a battery replacement. Does anyone experienced a battery/car damage if the code is not updated after battery replacement?
Thanks in advance.
