Despite the infamous "Self Level Suspension Inactive" fault i do not believe this exact scenario has been discussed.

2006 X5 4.8is

Quick Synopsis:
- Refreshed all four corners with Arnott Bags (sport)
- Cleared Codes with my Mechanic friend's Snap-On code reader
- Started to drive the car around the block and heard the compressor running but wouldnt shut off even after 2min.
- All air bags seem to be inflated and in correct position.
- Reran the code and noted "Front Left and Rear Left Solenoid Valve" fault.

This led me to think the Valve Unit on the compressor is bad but the previous owner had this replaced along with the Accumulator by the dealer 4months ago. Anything I'm missing?
Wondering if my Foxwell can provide any help

Plan on using the soapy spray bottle but I don't believe its a leak issue but ill double check? plan on driving down from Portland to Socal this weekend.
