So, more info.....
This all started when I was getting my SWS8 subs installed. My guy was checking something and disconnected the battery. He did nothing else that day. He reconnected it. Then the problems started.
Maybe, the car felt the battery was changed since the power was cut off. Then the ECU felt the voltage was lower than normal due to the wear on the old battery. So, it issues the codes and shuts of the power after stop (hence the clock reset and no comfort access).
Today it was in the 40s and the car is fine..... No codes and the access works and clock is holding time. Maybe the car adapted to the battery again???
Strange stuff. No matter, on Monday I will order the BT tool!!! I won't pay the dealer for stuff like coding the battery. I'd rather spend a little more and have the pro tool myself.
Thanks for tips all!
Btw, what do you all think of this battery?? Should I need one.... 900CCA and AGM. $179.
