Non-BMW Stuff on a BMW Forum

To make the R134A AC update, did you need to do anything additionally? I have not tried my A/C, but will be on the old stuff. Would be nice to have if I ever needed it.
Are you no longer running the clutch fan? Can you turn the fan on without having the A/C on?

You need to at least do a valve on the evaporator, new drier and pressure switch. I also did new evaporator and condenser and now a new fan.
I still have the clutch fan. The auxiliary fan comes on automatically with the AC on and mine wasn’t, that’s why I replaced it.
The tools worked as they should but I have a leak somewhere that all the Freon drained out. When I put in the first can I was hearing a hissing sound coming from the vents behind the hood. I thought it was the Freon filling the evaporator but now I believe it was a leak. The pag oil I put in has the uv dye in it but since the pressure never got high enough for the compressor to kick in, I’m not sure if the oil was cycled through all the lines to help me find a leak. I do have leak detector spray for gas lines in your house, so I may sacrifice a can of r134 to find the leak.
I read it’s not super uncommon for a leak to be sealed when the system is under vacuum and appear when it’s under pressure.

I’m struggling to identify where this is on the car.
Also, what’s the process for doing this?
Assuming that’s under the dash?
also, UV dye

I don’t know why I thought this was a fuel leak. That would make sense.

Correct. Under the dash. It’s the hi line from inside the car that was leaking a bit and then the low side at the fitting between the evaporator and the expansion valve.
It was a $10 UV flashlight from Walmart. Decided to grab that at the last minute but it was very worth it. Excited to say the car now has cold AC. It’s actually a little better than my XC70. That probably needs a charge - which I can now do.

How’s the new rack been working?
Much better. Had a huge air bubble reveal itself on my way home last week several days after installing the rack. Thought I felt the PS getting weak and when I got home the reservoir was empty. But zero leaks. Topped it off and it's been all good since then.

The car has been running great for the most part. One nagging thing has been about once every other week I’d get home with an empty PS reservoir. I always thought maybe there’s a large bubble in the system since I completely drained it.
Confirmed today that’s not the case.
Pried one of the boots away from the steering rack and it was so full of fluid that it squirted out. It was under pressure.
Both seals are clearly blown out. Really disappointed with Rack Doctor. Will give them a call tomorrow but I can’t put on of their racks back in my car. I don’t trust them anymore. Will go with OE rebuilt unit from FCP.

Ive heard really good things about rack doctor. Id give them a second chance.

Major bummer... I've always heard really good things about them, hopefully they remedy the situation!

They're sending me out a new rack tomorrow. The guy there highly recommended against using synthetic dexIII ATF and suspects that was the issue. I just was used what the internets said to use.
Anyways, on a more positive note. My wife ditched the XC90 for a 2021 VW Atlas with the second row captain seats. They are a game changer for hauling three kids.

Interesting. I siphoned and refilled my reservoir over the weekend and it doesn't feel quite right. Could just be a tiny bit of air that needs to work itself out, but I am using Maxlife ATF. I like the Maxlife because the seal conditioners really seem to help reduce leaks in past experiences but if the “air”/lack of smoothness doesnt resolve itself I may try non-synthetic ATF
Atlas seems cool
