Wait so when you got it back it was high as hell, and now the new bag leaked to below normal height? Is that only on one corner?

Or do you have another leak from an original bag?

In my opinion the module is blamed for failure way too much when in fact it is incompetent technicians working on your car throwing parts at a problem they don't know how to properly diagnose because of the vehicles age (not current).

The module of mine was replaced by the previous owner before he sold me the car, but guess what, I had two leaking air struts which leaked down to the fender wells the morning after I took delivery of the X, and AFTER that 1300 dollar replacement, I still had a lingering code for the air pump.

Guess what? Previous owner left the X with leaking air struts too long, compressor burnt out of spec. I replaced it, cleared the module of errors and have been air suspension trouble free for a year and a half.

I doubt very highly that him replacing the module helped my X, because I still had issues when I received my car that had nothing to do with the module. If the module can't communicate or can't calibrate ride height that might be one thing. But I'm betting your techs are the problem.
