BMW 7 Series: Pressure Line From Connecting Piece To Rear Heater - A/C System
Notes
WARNING: Risk of injury! Refrigerant circuit is under high pressure! Follow safety instructions for handling R 134A refrigerant.
Avoid contact with refrigerant and refrigerant oil.
Follow safety instructions for handling REFRIGERANT OIL.
IMPORTANT: Observe SAFETY INSTRUCTIONS for raising the vehicle.
Risk of damage! Restart engine only when A/C system has been correctly filled.
Follow INSTRUCTIONS for opening and replacing parts in refrigerant circuit.
If A/C system is opened for more than 24 hours:
Replace desiccant insert for A/C system.
To ensure that the refrigerant is almost completely drained from the rear air conditioner:
In the diagnosis system under Service functions carry out the instruction for "Draining/filling refrigerant circuit".
Necessary preliminary tasks
- DRAWING OFF, EVACUATING AND FILLING THE A/C SYSTEM are not included in the time value given for this work operation
- Remove ENTIRE EXHAUST SYSTEM
- Remove heat shield at rear.
- Remove UNDERBODY PANELLING

Park Distance Control
The Park Distance Control of the F01/F02 is identifiable by the five
ultrasonic sensors on the front bumper. The
fifth sensor enables a high level of reliability in obstacle recognition to be
achieved despite the large front end
of the F01.
