1. I have had the system vacuumed and refilled
result: a hint of cold for a few minutes but then just ambient 80 degree air

2. ODBII - no faults

3. Compressor clutch engages and condenser fan works

4. Low pressure line was high on 1st canned R134a gauge check

Question: how would I determine if the issue is the Expansion Valve?

*NOTE: I have not tested with PSI hi/lo gauges yet
Take a look at this post and the thread it's in if it matches what you are experiencing. In our case, it was the variable displacement compressor. IIRC the Calsonic Kansei CSV717 variable displacement compressor became standard issue on all X5's with the 04 facelift. Previous to that I believe a Denso was used.
