ANYTIME and I MEAN ANYTIME you cross breed your trades unless its a Ferrari you are going to be RAPED. The only time you can get the decent deal on a good trade is to go back to your BMW dealer, so just sell it outright.
Look at it from Audis view. They are getting a lower end X5, that competes with their Q7 3.0s and they really dont want anything to do with it. They will ship it out to as possible to auction they dont want it.
Sell it your self and then buy what you want, unless you trade up BMW wise.
