I posted a while ago but these are the latest observations.

1.The yellow suspension light comes on after about 3 minutes of driving.(the outside temperature does not seem to affect it anymore, 3 minutes or so) )
2. The only thing grayed out after the light comes on is the Lift Mode.(regardless of the car speed)
3. I have not noticed the car to sag, even after leaving it overnight.(I measured it)

Should I continue to drive it until the fault becomes more obvious?

Yellow light means the system is over inflated. 2-3 people fixed this by replacing the pump due to the pressure released valve was faulty inside the pump. Drive more until it's fully confirmed.
This is also one of VCDS falsely reported. Search and find the posts to confirm.

So rebuilding the compressor doesn't solve the issue since it's only piston rings.Correct?
Can the valve be replaced?
If I take it to the dealer I wonder if the their diagnosis equipment can possibly find more.

When my turn comes, I'll open the pump and check the valve solenoid. I bought the piston kit but never replace. It's a $21 waste sitting and collecting dust.
