Hissing sound from behind the backseats.
Hi guys, i have a hissing sound coming from directly behind the rear seats.
You can hear it loud and clear even while driving especially if you fold down the rear center armrest.
Also even loud you can hear it from the trunk if you open it.
Hard to describe that sound for me, its a constant hissing sound, combined with a slight, very low burble kind of sound in the background.
I hope there is no ABC part there? Or is it the fuel tank (its pumps) ?

Sounds like you might have a air leak in your pneumatic system. The air pump sits right behind the seats. Does your soft close feature work?

Ok its not the pneumatic pump. The sound is coming from the left rear struts top end.
What is this? Air in it? Also this could explain the knocking noise i have from the strut.
