Could be relay for the compressor that causes it to run and then stop or a bad overheating comressor. When the one that does raise finally raises, does it hold an function correctly but just slow to raise? Is the compressor loud?

Every allroad owner should invest in a Ross Tech VAGCOM scanner. A lot of used ones float around for cheaper since we dont need the CAN funtions (KII-USB and Key-USB work great)
The airbags can be solid at some levels yet leak at others. Level 4 is the least likely to leak usually. L2 and L1 are more likely, so try letting them sit overnight on either of those.
Maybe you can find an indy or someone local with a RossTech cable to scan for you.
