HELP: "SELFLEVEL SUSP INACT"

[Steve972]

Hi everyone, I have a 2001 X5 4.4. I wanted to see if anyone has had this problem, and fixed it on their own before I go back to the dealer. I noticed that there are serveral posts on other sites about this issue? Is there a quick fix that I can do on my mine or do I need to go back to the dealer? People have suggested anything from "air supply control unit" to sensors, to faulty fuses. I am not sure where the fuses would be located or where the sensors are? I was also told that since I upgraded my rims/wheels from 18" to 20" aftermarket BMW look alikes, that I would need the dealer to reset the computer so that the X5 realizes the new tire configuration. Is this true? Geeeeeeeeeeze If I sneeze in the car, do I need to go the dealer for that too, Seems like I am running to the dealer every other week.

Please let me know if any of you have experienced this problem, was there a quick fix?? how do you reset a computer on these cars?

Thanks in advance...
