Short version:
Why is the Compressor Current (actual) field empty? Is that normal? No error codes.

Long version:
Hi, on vacation, A/C is no longer cooling properly and it's 35C/95F outside with strong sunlight.
I don't have graphs (new to this, sorry) but short explanation of the values:
Refrigerant pressure: Started at 7.8 bar (off) and went to 10.2-11 bar when on. I think this is normal from what i read.
Evaporator Temperature: this is dropping only very very slowly. It should go down to 4C over 5-10 minutes but after 15 minutes it was only at 28C (down from 35C at start).
This was in a parking lot idling but i noticed the problem while driving. Don't have low pressure gauge at the moment (trying to get one). Don't speak the local language AT ALL and the locals don't like to speak english :|

Start and run engine, crank AC to coldest settings. Now take a look at the Compressor Shut-Off code found in 08-08-001.1.

If that value is 0 or 0.0, then odds are the compressor itself has failed.

Please look at compressor shut off condition.I would say possible low freon charge. Low charge symptom are usual warm cabin temp at the vents or empty system due to a leak or a failed compressor.

It can (sometimes) just be the control valve itself, though usually you'd find it very occasionally works or seems to, at least. If you watch the pressures and turn the ac on and off, it should respond failry quickly. If the valve is stuck or blocked it can be very slow to change pressures.

If the valve is stuck, they can be replaced, if it's blocked, lumps have usually been traveling through the system (especially if it has one of those shitty zexels with the faulty internal coating)

The ones we get tend to be Sanden and we replace then with Denso
I just received my new Denso compressor, condenser, drier etc. :thumbs: it seems the order of explosion likeliness, from most to least, goes Zexel; Sanden; Denso.

Luckily, mine just became noisy and hasn't pushed shrapnel and black death through the system!
