    How old is the battery?

    A lot of weird things can happen on a MINI when the battery is going bad.

    Maybe a year , I figured that the camshaft postion sensor could cause the o2 sensors but the ac is puzzling

    You will know if it is in limp mode. It will have no power at all. Did you shut off the car and restart it? if so did anything change?
    I would start with checking all your battery connections. Make sure they are corrosion free and tight. Don't forget the Positive bolt under the hood with the + sign on it, they have been know to get loss. Then have the battery checked. Not just the volts but have a load test done on it. Any parts store can do it for you. After this is done clear the codes and see what comes back. If the crank position comes back I would change it.
    Good luck and let us know what happens.
