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

Did you flush any A/C flush or alcohol through the system? I run a flush or IPA when a compressor is replaced. A flush will remove debri and old oil out. High pressure on the low side means something is restricting flow. Low pressure compressed air will flush out IPA and dry it. Since the compressor is new, remove it. Flush all the components. Replace the dryer. BMW E53 X5 AC Drier 64536942025. AKA, orifice tube. The clog is likely at the drier. I've replaced a lot of those in different cars. Especially after a compressor failure. All the debris gets caught there.

So, turns out a total cluster of errors. Mainly the seals in my manifold gauges were buggered and giving me all sorts of bad readings. I took everything apart on the engine side of the system. After putting in a new filter drier and now getting high high pressure readings. I concluded my condenser is nearly fully blocked. My aux fan has been dead forever, but AC always worked just fine. I took my electric leaf blower and blew over the condenser and sure enough, for some cold air and lower high pressure. I assume this extra air helped with the restriction, but condenser is the issue. I'm contemplating swapping the Aux fan with a cheapo replacement. I don't see myself spending $600 for a Behr fan. Thanks for the support all.

Mine has a brushless replacement aux fan. TOPAZ 64546921381
After turning off the engine, it can spin for 32 seconds! Brushless fans are very efficient. Mine has been running in Texas heat for almost 3 years now. A/C vent temps get down to 42F! Even a bit lower at highway speeds. It's so cold after cooling off the interior, I can run the fan speed at the lowest setting and be comfortable.

Where is the dryer? Is it a change on schedule type of part, or do they not normally need changing? My AC blows a frosty gale since it was evacuated and then recharged for the motor change, and I'd like to keep it this way.

The dryer is in a tube attached to the condenser. It's part of the condenser. Honestly, unless your system is open for 24 hours or not working, I would not be changing it regularly. You have to evac the refrigerant and recharge. My old drier was fine for 20 years and when I looked at it, it still was ok, not blocked. Discolored yes, but easily passing air through it, like the new one.
I am interested in the topaz fan, just wonder how loud it is and if any of my other components are dead which would cause the fan not to work. I suppose they are likely fine and it is just the fan. I will order one. Thanks.

I haven't been running an AUX fan for 6 years, but I only hit 105c then it immediately drops to 102c when the temps are above 43c+ over here..... Sent from Embassy network using Tapatalk

Does fan run at hot idle operating temp and A/C off? If not, the fan is probably toast. My Foxwell 520 pro is bidirectional. I test mine fan on occasion. However, I can hear it spin down after engine shutoff. The fan is surprisingly quiet. You can hear it if the radio is off.

Topaz fan ordered. Seemed like Amazon was best deal, $105 before tax. I watched the videos on how to replace. Seems okay, but wonder how loose I need to make the metal bumper without taking it fully loose and making it a total pita to reinstall.
