In deciding to remove the battery and battery tray to replace the dsg oil filter I found out what is reset in the computer. There appears to be three things that power loss causes in the car.
1) the steering light is lit, the esp indicator is on solid, and the brake light is on. To remedy that, I had to turn the steering wheel hard left, then hard right, then center. When I did that (in my case) the indicator lights cleared.
2) the windows had to be run down and the buttons held for one second, then the window were run up. This did the "window reset" .
3) The last problem did not show up until I tried to play my ipod through the Aux. input. I discovered that pressing the CD button did not put the radio into aux. in. This turned out to be the hardest problem to solve.
Fortunately, when I bought my vcds cable I did a full diagnostic scan and stored it in the log file right away, thinking I would look through the file later (out of curiousity). When I ran the diagnostic on the radio using vagcom, I found 5 faults.
00870 - bass speaker front left (r21) 011-open circuit
00871 - bass speaker front right (r23) 011-open circuit
00872 - bass speaker rear left (r15) 011-open circuit
00873 - bass speaker rear right (r17) 011-open circuit
00003 - control module 014-defective.
By comparing the software coding from when I first had the car with no faults my coding was 0010011.
After the battery was back in the car, the coding was 0010400.
Hope this helps out anyone who plans on replacing their battery . . .
