A/C Compressor Regulator Valve -N280-
NOTE:
Switching pressures, removing and installing switches as well as switch arrangement and version. Refer to Air Conditioning (1 Of 3) / Air Conditioning (3 Of 3) (vehicle-specific Service Information).
- 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 Air Conditioning (1 Of 3) / Air Conditioning (3 Of 3) (vehicle-specific Service Information).
- 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 .
