Volkswagen Polo Service & Repair Manual: A/C Compressor Regulator Valve -N280
 Note
| For switching pressures, removing and installing switches
and switch arrangement and version, see vehicle-specific
refrigerant circuit. |
|
|
|
| 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. |
