So I replaced my battery myself and registered it myself with my KD-can cable. I did not lose any coding. I have custom coding in FRM, CIC, COMBOX, ABG, CAS AND KOMBI. My only thought for your experience is too much time passed between battery removal and new battery hookup. I do not believe the ECU's in the car have NVRAM. So if power is gone too long the 1's and 0's become decayed, undefinable and ultimately corrupt. Hence default based off VO afterwords.
