I did reset it but it didnt seem to do anything since there arent any sensors in place to be reset.
Thanks a lot.

I don't believe the X5 has any wheel sensors.
BMW RPA (Run Flat Indicator) principle: If a tyre loses pressure its rolling radius changes, and this in turn alters the speed of rotation.This change is detected and reported as tyre failure.
That means the X5 like other BMW cars(5 ,6 ,7 series) uses the abs
wheel speed
sensors and detects a change in
wheel speed as the rolling circumference of the tyre changes when deflated.
