X5 E53 (1999 - 2006)
I am fairly new to the forum and have just purchased 2001 X5 4.4i with 87K miles.
and drove it for a few days and suddenly the SELF LEVELING SUSPENSION INACT. showed up on the screen.
I turned the engine off and then on and disappeared for a couple of days.
Then I noticed it would come on again...
