Default Troubleshooting air suspension

Long time no chat. I am no longer a government employee so I don't have nearly the amount of free time I had before to spend on the forum.

Does anybody have a troubleshooting diagram for diagnosing suspension ailments?

Car has been stuck in level 1 for months now so I guess its about time to figure it out. My guess would be it's the valve block, but how to no for sure?

The air tool oil trick didn't work. What sort of pressure should the pump be putting out? Not the system pressure but the pump itself.

By the way, the tire slime in the LF air bag is still holding strong! It's been about a year and a half now.

First place to start is to get the codes read with VCDS/Vag-Com...

So I got the VAG working on the new laptop. I didn't think it jived with Vista, but apparently it does. No codes came up for the suspension, and when I try to connect to the suspension controller in VAG, it can't.

What up with that?

Default Since it won't recognize that address, I am with Paul...

and I have to say it is the module.
