BMW X6 E71 REAR AIR SUSPENSION SAG

[xr8er]

Hi Guys anyone has any experience with an x5 or x6 e7x series rear suspension sag. not sure whats the problem because some days the air suspension stays up for days and some days it goes down within 1 hour. not sure to replace the bags or controller unit etc. any one in Durban would be preferable. thanks
