Help with my Disco II

2000 Disco Series II

Just got this Disco about two weeks ago - it's my third. Prev had a 2002 and a 2001.

After I turn off the car and get out I hear a loud "whoosh" noise of air escaping. Is this normal? I'm assuming it has to do with the air suspension.. It's been happening the last week or so. Unsure if I just didn't hear it before...?

Thanks for any help you can provide!

Ah, try posting in the disco section. "Series" in this context means older series land rovers.
