Hey,

Sorry everyone if here isn't the right place to raise this topic,

I'm currently having troubles with my AC that stopped working at 100%.

A few days ago my AC stopped working on the front area of my car, so this is a weird behaviour because when I turn it on the only place where the air comes out is really in the back seats.

So in the car's front, the air doesn't come out anywhere.

I tried some troubleshooting steps but so far no changes and after a INPA test this came out:


ERROR MEMORY

9C52 44
================================================== ===============

Does anyone here is familiar with these errors?

For what I understand, these are the errors related with this problem:

12 DME/DDE OKAY 2 Error stored
43F2 44

and

78 KLIMA OKAY 8 Error stored
9C48 64
9C49 64
9C4A 64
9C4B 64
9C4C 64
9C4E 64
9C50 44
9C52 44


Now I found what's the error "43F2"

And it's related to 43F2 Electrical Aux Heater - Activation Interrupted

but I didn't find nothing related with the rest...

Any thoughts?

Thanks in advance

Check this out—

I looked up the codes for 9c48 and 49 and they were for mixing flap motor...

You have to do a captcha for each code so I stopped there

Thank you so much for the help, this website is awesome!

I was about to post a question on INPA and A/C. I hope it's OK if I tack on here?

Is there a menu in INPA to run diagnostics on A/C?
I know on Audis, I can check the ambient and running A/C pressure, compressor function to see if it triggers etc.
There must be a similar menu for INPA, right?
Or does ISTA have a diagnostic procedure?

My A/C is very weak, almost not there. I don't have any error codes. So, checking the refrigerant pressure is my first step.

I've never done that with inpa or ista, just an external gauge.

OK, to answer my own question and contribute:
To check the refrigerant pressure with INPA, go to
Body > Air Conditioning > Status > Analog

The "Print Cooling agent" (we can only assume "print" = "press" = "pressure" haha!) [bar] shows the pressure. The correct value depends on the ambient temperature and can be looked up in R134a charts.

Any tips for installing INPA and does it work with an USB to ODB cable?
