No AC - is this going to put my X out to pasture?

[Meestahbig]

Well, I swapped the compressor yesterday with a brand new one (did this once before with a junkyard compressor and thought this time the clutch was maybe slipping - causing no cold air). New compressor in, I pulled vacuum and then added a little 134a. Compressor kicked on but still seeing same problem as before.

Low side was reading like 80+ psi, High side wasn't building pressure, was low like around 50 psi. Compressor was definitely engaging. The system barely took any charge at all so the system was really filling, but filling enough to allow compressor to kick on.

So now I'm stuck. Don't know what to do next and next steps aren't simple. Getting to the expansion valve or evap requires ripping apart the dash. Could be condenser coil and filter drier, but I haven't found any info indicating it would be this over the expansion valve.

I am using the X5 as a daily driver still with 210k miles. I really don't want to let it sit until fall bc I think then, it might develop other issues!

ANY HELP OR THOUGHTS? Maybe bring it in to get an assessment from a proper repair shop? Let them tell me fore sure it's the expansion valve?
