B750Li

Newbie here. Hi I've recently gotten a 2009 750li with 83k on clock. Put it into sport mode and drove it. Now the back suspension has dropped and body is almost touching the wheels. There is a hissing sound coming when I leave the car. Seems like the air suspension pump is trying to raise the back but leaking out. Anyone had any similar issues. Please help

Welcome to Bimmerfest!

I moved your posting to the F01/F02 forum (7 Series, 2009-2015) so you can get model-specific help.

Welch to the club, I have 191 k on my 2009, amazing car, but not cheap. This happened to my wife’s jaguar, the bag in the air suspense leaked, they had to replace that strut, not cheap.
