Multiple error codes, won't start, after trying to reset service interval

Ok, here's the story with my 05 525i:

Changed the oil, started the car to check for leaks, it runs great, everything's fine. I turn the car off, and go to reset the service interval through the trip duration button. I held the button too long and it went in to the german text with the codes. I pushed the button a couple times while in there. Then turned key back to Off to try again. Turned the key back to On and everything goes absolutely haywire. Get multiple error icons, probably every error it has - transmission, window, car movement, ABS, etc. THe gear indicator starts indicating Neutral and then Park and then back again..., and the interior light starts flashing. Try to actually start the car, and it turns over once or twice, then click click then nothing. Eventually all lights go out. During this sequence the iDrive screen is dark and inaccessible.

Try the key again a couple times, get the same thing. Still no iDrive either.

I then disconnect negative batt. cable and let it sit for a while, see if it resets or anything. I reconnect, put key back in. Actually seems like it could be fixed - with the key in the first position, the air system starts up like normal, iDrive comes on, all looks good. Then I turn the key to the On position and everything falls to pieces. Won't start, electronics gone crazy like before.

Does anyone have any suggestion?? I'm stuck with no car and no idea where to start short of towing to a shop. Possible ideas:
1) I saw forum posts with similar symptoms suggest replacing IVM. Could I have fried it by pushing the reset button incorrectly or something?
2) Also thinking or hoping the battery could be low?
3) Possible I cleared the computer programming accidentally? Is that even possible through the button menu?

Just a little surprising I could have done this kind of damage through accessible electronic menu.... Any help or suggestions would be really great. Thanks

It sounds like your batt is low or going bad . you have to have constant 12 volts or everything will go haywire. check batt with volt meter u should have 13 or 13.5 volts or you can turn everything on and blow the horn to see if it sounds weak
