SelfLevel SUSP.INACT warning appears...why?

***Update***
I pulled the bottom cover off from under the passenger side again tonight and soaped up every inch of the air system from front to back. I shot soapy water up on the front and rear bags and every fitting. I took the trunk apart again and soaped up the lines and fittings there too. STILL NO LEAK FOUND...

I was continually running back to my laptop to air up the system and then checking the dripping lines while the car dropped.

Now we get to the part that I'm almost embarrassed to admit...

I had left the trunk lid and driver's door open long enough to wear down the battery. So I popped the hood to put the charger on. With the hood up and the laptop connected, the air system inflated yet again and there it was. The faintest hiss coming from the passenger side strut tower. I shot some of my spray solution at it and sure enough, bubbles...
I pulled the large black cap off and applied more solution, big bubbles.

Now is when I discover that the 14mm nut in the center is nearly ready to fall off due to the F@#*ING idiot that improperly installed it.

The dealership I bought the car from had the strut replaced just before I picked it up. Apparently they damaged about half of the threads on the nut and didn't have another one to install. So rather than getting another one, they ran it down until it stopped which was about 4 threads in.

Now, I know the bag is BRAND NEW as of 3 months ago. Does anyone have hope that a new nut and tightening this thing down will allow it to reseal??? There is noplace open this time of night to get an odd metric nut so I'm on hold until morning...
