This is great info.... Thanks a lot James 4.8is....
For my X5, I found this info:
Vehicle inclination
There can be a wide variety of causes for a vehicle inclination. The causes usually lead to an entry in the fault memory of the control unit or to a CC message in the instrument cluster.
Causes for vehicle inclination
Sensor causes
Checking of the sensor system according to instructions in the adjacent diagnosis test module.
Mechanical causes
Sensor linkage (position, defective)
Sensor holder (position)
Securing clip of the sensor linkage (position)
Leaks as causes
Leak in the lines
Leak in the valve block
Leak on the spring strut
Electrical causes
Water in the connector (corroded pins): With this fault, a creeping inclination begins, as the signal slowly drifts away.
Short circuit in the 2-axle air suspension system (but this is normally stored by the control unit as a fault and detected via diagnosis).
System-specific causes
Opening a vehicle door during a change in the ride height (vehicle at a standstill) can cause a vehicle inclination.
Rapid forces being exerted from the outside (attaching a trailer, fast loading or unloading) can prevent regulation.
Tolerance bands with ignition on: +/-10 mm to height value from TIS. Note: In the case of the front axle, the mean value of both heights counts.
Tolerance bands with ignition off: +15 mm/-20 mm to height value from TIS. Note: In the case of the front axle, the mean value of both heights counts.
Temperature deactivation
