R8 Quattro Coupe V10-5.2L (BUJ) (2010)
Discharge Air Temperature Sensor / Switch: Service and Repair
A/C Pressure/Temperature Sensor
‹› The A/C output cannot be checked when the A/C Pressure/Temperature Sensor (G395) is removed. The Climatronic Control Module (J255) does
not switch the A/C compressor on.
‹› The refrigerant circuit remains closed, connection with valve.
‹› For checking the A/C pressure/temperature sensor measured values, refer to Vehicle diagnosis, testing and information system VAS 5051/
under"Guided Fault Finding".
‹› The A/C pressure/temperature sensor exchanges information with the Climatronic control module via the LIN Bus A/C databus system.
‹› The temperature measured by the A/C pressure/temperature sensor differs from the actual refrigerant temperature because of the A/C
pressure/temperature sensor design and its component location. Because of this, it is not currently evaluated and is not used to regulate the A/C
system.
‹› Only the A/C pressure/temperature sensor may be installed in the Audi R8 (gray housing color).
‹› A High Pressure Sensor (G65) may not be installed in the Audi R8 (black housing color) (only delivers square-wave signals).
