So I've bubble tested the valve and surprise......it leaks.
The weird thing is that it leaks at the nipples 
All 4 valves hold pressure, but one of the nipple that go to the bags leak. It's a brass tube pressed into the plastic end piece. After the bubble test I've noticed, that I can move it a bit. I tested it from 0 to 25psi and no other leaks. I guess anyone who willing to take their seat apart just need to do a bubble test to see if it has the same problem. Just inflate the bags and unplug the wires. You don't need any power to hold pressure only to inflate or deflate. Sorry about the crappy cell picture.
