Hey!

As you know maybe on the Climatronic of this car, if you press the button ECO or AC in combination with the button "ventilation up" there an hidden menu opens. In this hidden menu you can get different data, for exemple if you go on menu 19-2 (on the left hand side display) you will get coolant temperature of the right hand side display.

Now I had a look at the menu, 10-0 (evaporator temperature) and 10-1 AC system pressure. My idea was to see if there was still enough R134a in the system. So but putting the AC on LO (lowest setting) for 2 minutes, I had a look at the values and what I get is the evaporator going to 1-2 degree celsius with at maximum of 7 bars of pressure (which tended to get lower and lower but I assume because the evaporator was already near 0 degrees).

However I have a feeling that a maximum pressure of 7 bars @ 25 degrees celsius (100 psi) is very low for an AC system. What do you get on yours?

Thanks
