• The coolant performance cannot be checked when the A/C pressure/temperature sensor is removed, the Climatronic control module (J255) , does not switch on the A/C compressor. Check using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
• The refrigerant circuit remains closed, connection with valve.
• Only the A/C pressure/temperature sensor may be installed in this vehicle. Refer to Electronic Parts Catalog (ETKA).
• The High pressure sensor (G65) must not be installed in these vehicles (only delivers square-wave signal is emitted).
Removal
- Remove the lock carrier cover.
- Disconnect the electrical harness connector - A -.
- Unscrew the A/C pressure/temperature sensor - B -.
Installation
Installation is done is reverse order, observe the following:
- Replace the O-ring seal - B -. Refer to => [ Refrigerant Circuit O-rings ] Refrigerant Circuit O-Rings; and Electronic Parts Catalog (ETKA).
- Tighten the A/C pressure/temperature sensor - A -.
• Tightening specification: 5 Nm.
After completion of the repair work, perform the following work on the control head using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
- Read out the event memory and erase any displayed entries.
