If they filled by weight as upallnight said, it's possible they could have put in the right amount. Did the AC work after the drain and fill?

However, after thinking about this more .. If the car has not been run today .. and it is 75 degrees here, there would NOT initially be hot coolant flowing through the core.. and if this were the only issue then I should have initial AC of some sort and then it would get hot with the car..

Voting : Agreed ? / Disagree ? / Makes no sense?

I was also reading on how some HVAC systems actually have what is called a "Blended vent system" which is control flaps that separate the heating (heater core) from the cooling (Evaporator). Seems like X5 E53's have a lot of flap valves but I am not sure if it is only for the airflow itself OR if it is truly a blended - in my example I mean ..

A flap which must move in order to allow ether of the following two conditions:
1. heater core HEATED air to enter the cabin
OR
2. Evaporator CHILLED air to enter the cabin

As I am writting this.. I am remembering 2 facts, (1) my gauges are showing LOW Freon @ 37PSI (2) the gauges read same low 37PSI on both the LOW side and the HIGH side... the High side should be reading around 145PSI @ my outside ambient temperature of 70F.

This would suggest a bad compressor; however, the low pressure fill port shows full @ 37 to 50PSI .. so for some reason perhaps something is blocking the Freon from filling ?

IDK

Please feel free to chime in with any additional thoughts or consideration here.
If your heater control valve is bad it will throw a code. My wife's AC was blowing warm. Checked and it had proper coolant charge and the compressor was working. Ran it for codes and it showed a bad heater control valve. Stuck wide open. Replaced the valve problem solved.

Thank you Fifty150hs!

Im not throwing any codes for ac related items.. I think I have just taken in so much info that Im all over the place thinking out the possibilities

I think Im going to go back and have them rerun an Evan and fill ++ the shops .02 and then double down on a new compressor if it doesnt work still.

The shop should not have released the car without either working AC or a reason why.

Ok so they weren't able to fill it. Did they say it wouldn't take a charge or did they fill be weight ? (Questions to ask). I'm betting that the variable function is broken and not compressing.

Sorry to thread jack however I didn't want to start ANOTHER ac thread.
2003 3.0
Mine stopped blowing cold, 95-100 degrees here everyday. I can't really dive my kids around.

Condenser turns-on
no codes
low side is around 50psi
I don't know high side

aux fan does not turn on with AC - I can activate it with my schwaben scan tool
aux fan turns on when I unplug the sensor wire
aux fan does not turn when car warms up

I'm stumped???
Would love some help.

On the low side? 50 psi is too high according to BMW.

Max on the low side is 2.2 BAR. https://www.newtis.info/tisv2/a/en/e...-check/Oke6MtR
