A/C Compressor Regulator Valve -N280-
WARNING: This page is about a different car, the 2023 Audi SQ8, 2023 Audi RS Q8, and 2023 Audi Q8. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Switching pressures, removing and installing switches as well as switch arrangement and version. Refer to Refrigerant Circuit (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 and refer to the Refrigerant Circuit (vehicle-specific service information).
- Pressure on the low pressure side is influenced by 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 Refer to A/C Compressor Regulator Valve -N280-, REMOVING AND INSTALLING, AND REPLACING .
