Instructions for opening and part exchange in refrigerant circuit (X6 2015-2019)

Required Special Tools:

00 9 030
32 1 270

WARNING:

Avoid contact with refrigerant and refrigerant oil
Follow safety instructions for HANDLING TETRAFLUORETHANE REFRIGERANT R134A .
Follow safety instructions for HANDLING REFRIGERANT OIL .

Attention!

Always use new O-rings each time A/C connections are opened (refer to applicable BMW parts catalogue) They must not be coated. Use special tool 00 9 030 to install sealing rings without damaging them.
Open the refrigerant circuit for as short of a period as possible.
Close all components and lines in the refrigerant circuit and return parts immediately following the removals at openings with special tool 32 1 270 to prevent penetration of moisture or foreign objects.
If the refrigerant circuit was closed at the openings with special tool 32 1 270 but it remains open for more than 24 h, the dryer insert for the air conditioning must be replaced.

Part replacement as preliminary work for further repair work and part replacement based on gradual leakage .
(minor leak, e.g. hairline crack)

Procedure:
- Suction heating and air conditioning system. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) REP-REP-RAI0164-6450010 BMW I - V.18 (X6 2015-2019) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) REP-REP-RAF0164-6450010 - V.42 (X6 2015-2019) , then determine suctioned coolant oil level
- Carry out part replacement
- Replace removed refrigerant oil and additionally top up with new refrigerant oil according to components replaced:
  - Compressor: refer to NOTES ON COMPRESSOR REPLACEMENT .
  - Evaporator: 10 ml
  - Air conditioning condenser: 20 ml
  - Desiccant insert/dryer flask: 20 ml
  - Each replaced refrigerant line: 10 ml
  - Air conditioning condenser with integrated dryer flask: 40 ml
  - Safety pressure switch and gasket: no additional refrigerant oil
  - Only I01: Radiator, high-voltage battery unit: 20 ml
- Evacuate and fill air conditioning system. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) REP-REP-RAI0164-6450010 BMW I - V.18 (X6 2015-2019) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) REP-REP-RAF0164-6450010 - V.42 (X6 2015-2019) .
Part replacement due to sudden leakage
(major leak, e.g. pipe break due to accident)

Procedure:
- Suction HEATING AND AIR CONDITIONING SYSTEM , then determine suctioned coolant oil level
- Carry out part replacement
- Replace removed refrigerant oil and additionally top up with new refrigerant oil according to components replaced:
  - Compressor: refer to NOTES ON COMPRESSOR REPLACEMENT .
  - Evaporator: 35 ml
  - Air conditioning condenser: 35 ml
  - Desiccant insert/dryer flask: 55 ml
  - Each replaced refrigerant line: 35 ml
  - Air conditioning condenser with integrated dryer flask: 55 ml
  - Safety pressure switch and gasket: no additional refrigerant oil
- Evacuate and fill A/C system. Refer to 64 50 010 SUCTION, EVACUATING AND FILLING AIR CONDITIONING (R1234YF) REP-REP-RAI0164-6450010 BMW I - V.18 (X6 2015-2019) or 64 50 010 SUCTION, EVACUATING AND FILLING HEATING AND AIR CONDITIONING SYSTEM (R134A) REP-REP-RAF0164-6450010 - V.42 (X6 2015-2019) .
