Hi,

Does anyone know at what pressure the high pressure cutout switch operates on an 03' 8L A3 with climate control?

using the error code function on the the CC unit i get 22.3 which is spoadic opening of the switch.

is it possible to erase this message to see if it comes back and if there is more than one message how do i scroll through them?

cheers

steve
 
A3 Steve. Seems that there are 2 different systems available and it doesn't when the change over was. Below is some of the stuff I got from elsawin. If you pm me with an email address I'll send you everything
High-pressure switch for air conditioning system -F23-
Function:
Switches radiator fan up to next speed setting in the event of pressure increase (approx. 16 bar) in refrigerant circuit.
High-pressure switch for magnetic coupling -F118-
Function:
Switches off compressor in the event of excess pressure in the refrigerant circuit (approx. 32 bar).
