  Note
For switching pressures, removing and installing switches and switch arrangement and version, see vehicle-specific refrigerant circuit.
Refer to → Rep. Gr.87.
   
The regulator valve is implemented into the compressor. It is activated by the A/C Display Control Head -E87- or Climatronic Control Module -J255-. 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.
