AC won’t run until engine is warmed up??
So the AC on my 2005 525i is working perfectly fine, the only issue is that the compressor won’t kick in until the engine reaches operating temperature. I’ve been dealing with it for years but I want to fix this once and for all. Any ideas as to what’s going on?
Took it to a friend of mine who codes, he found this setting for the climate control that would seem to be the most plausible setting but it’s set to inactive?
I attached 2 other settings he found but he doesn’t believe those would be related. Could they be? And is this feature pictured above opposite for some reason?
Is there anything else we could have missed? Any help/insight would be greatly appreciated to I can finally have a comfortable summer

I have never heard of that. Your coding looks fine. I wouldn't think this would be a coding issue anyway. Readout your errors in INPA and post them. I'm sure you have a AUC sensor error

Hmm, I’m going to have to go back to my friend who codes so he can get the error codes if there are any.
I’ve heard plenty about the AUC. Can someone confirm where it’s at? If I’m looking at where it should be based on what I’ve seen online, I’m either missing one, or it’s elsewhere on my car (2005 525i M54)
(please pardon how dirty my engine is. Allergy season is high where I live right now and I cannot take the time to clean it)

Alright I’ve been getting 2 different answers of where it’s at on an E60. Looking at my fan shroud I found this, this is the AUC right?

AUC sensor will not have anything to do with poor A/C performance. It only decides when to change to recirculate air if the car button for auto-recirculate is enable.
The Condensation Sensor lives just under the rear view mirror and that is a common failure especially if you have had a windshield replaced. This can affect A/C performance. Even if yours is complaining, I doubt that is the source of your problem.

I have not had my windshield replaced, could be the sensor had gone bad. But what’s the difference between that sensor which sounds like it only detects condensation on the windshield, and this solar sensor that sits on my dash according to this diagram from realoem? And which would be a more likely culprit to fix my delayed A/C start?
