you can put tyhe cluster from a 4.6/4.8 into any x5, the dealer will program the kms from your existing unit into the new one, however you must remember that on your existing cluster you have a gauge at the bottom that tells you you kms to gallon, on the 4.6/4.8 it is an oil temp gauge, it still works but it stays on high all the time, the lights on the rev counter work to, when it's cold first thing in the morning they light up like a christmas tree after that you just have the red one's on.
