A/C Compressor Regulator Valve -N280-

NOTE:

Switching pressures, removing and installing switches as well as switch arrangement and version. Refer to REFRIGERANT CIRCUIT

The regulator valve is installed in the A/C compressor. It is activated for example by the A/C Control Module -J301-, the Front A/C Display Control Head -E87- or the Climatronic Control Module -J255- (depending on the vehicle, possibly via the data Bus and an additional control module). Use the Vehicle Diagnostic Tester in the A/C system "Guided Fault Finding" function. Refer to the REFRIGERANT CIRCUIT

Pressure on the low pressure side is influenced via the regulator valve and thus regulates the temperature in the evaporator.

NOTE:

The A/C Compressor Regulator Valve -N280- is a component of the A/C compressor and cannot be replaced separately on all A/C compressors. Refer to the Parts Information and A/C Compressor Regulator Valve -N280-, REMOVING AND INSTALLING AND REPLACING .
