I have a 97 mark8, I have rebuilt the air ride from top to bottom. new bags, solenoids, height sensors, pump, dryer, and lines. But the darn thing just won't work, it will be fine for 2-3 months and then a bag won't inflate. Its always a random bag. The thought happened, what if I were to use an after market compressor(or wired the existing compressor to run via a pressure switch mounted on an air tank) after market tank, solenoid pack, and have the existing bag mounted solenoids wired to stay open at all times. If anyone has any ideas please comment.
