If your D3 A8’s air suspension is stuck in lift mode, it’s likely that you have a defective residual pressure valve. The A8 has one of these valves on all 4 corners and if just one of them fails, the car will raise the other 3 corners and make the entire car sit higher. You will know that a valve is stuck or defective when removing the air line to the strut. If only a small amount of air comes out, then the valve is likely stuck or defective. You should replace the valve but you may get away with just removing it and reinstalling it. If the issue comes back then just replace the defective valve. I have seen the part online for $20-50 on average. Subscribe to the channel as I have more DIY videos like this coming soon!
