Suspension issue

[JohnG123]

I have a 2015 X6M,car as done 13500 miles with no mechanical issues.

Left car parked for 3 days on level ground.
Went to get in car this morning and the whole car was leaning over to one side.
So bad that I thought I had 2 flat tyres on the passenger side.
When I walked and looked both tyres were fine but the whole car was leaning over.
Got in the car to go to the local dealer played with the suspension setting from comfort to sport plus and back again parked up and the car was level again.
No faults came up when I started car,but car was defiantly leaning over.

Any ideas ?..

Chances are you have a leak in one side of the rear air spring. When you turn the car back on it pressurized it again and back to normal ride height. I am willing to bet that if you parked it for another few days it will happen again until that one air spring is replaced. Should be a simple fix for the dealer.

Many thanks I will keep my eye on it.

Another possibility: something went wrong with the hidraulic active roll bar circuit, the one that keeps the car horizontal during a turn.

The fact that, by switching between Sport+ and Confort settings, the car was straightened may suggest to check these parts: suspension height sensors, roll bar actuators and its controlling software.
