Hi I recently got a trailer and I am having issues with the 12v aux output not charging my battery at all. I happened to check my module 69 coding and found the code to be odd. From all I've read it should be 0000002 or 0016386 but mine is neither. It is showing as 0002050. Should I change it to 0000002 as my unit is a 7l0 907 383L. I doubt this will fix my charging issue but I figure I should at least make sure i have the right coding value. I have an 08 V8 with air.
