Attention!

This procedure is only applicable to:

  1. Countries, in which BMW i vehicles or hybrid vehicles are delivered with

R134a refrigerant.

  1. Workshops in these countries that do not have a separate A/C service station for BMW i vehicles or hybrid vehicles.
  2. If a BMW i vehicle or hybrid vehicle (R134a refrigerant, Sanden SP-A2 refrigerant oil) must be filled with an A/C service station for R134a and the vehicle’s expansion tank is filled with ND-8 refrigerant oil.

Observe notes on refrigerant and refrigerant oil from 09/2013!

Necessary preliminary tasks:

Evacuate refrigerant circuit and fill with refrigerant.

Vehicle with heat pump: The connector pulled off in the previously mentioned document remains disconnected until completion of refrigerant oil filling process.

(Do not fill in refrigerant oil)

Disconnect refrigerant lines of A/C service station from high pressure and low pressure connection on the vehicle.

(A/C service station no longer needed)

Define amount of refrigerant oil to be filled in:

Parts of refrigerant circuit were not replaced:

Amount of refrigerant oil to be filled in = amount of refrigerant oil drawn off by means of A/C service station +

4 millilitre extra amount (for volume of hose)

Parts of refrigerant circuit were replaced (air conditioning compressor excluded):

 

Amount of refrigerant oil to be filled in = amount of refrigerant oil drawn off by means of A/C service station + extra amount for new part +

4 millilitre extra amount (for volume of hose)

When replacing A/C compressor:

Amount of refrigerant oil to be filled in = amount of refrigerant oil drawn off by means of A/C service station + amount of refrigerant oil defined of previous air conditioning compressor +

4 millilitre extra amount (for volume of hose)

Fill in amount of refrigerant oil to be filled in into a clean measuring cup.

Filling refrigerant oil by means of injection BMW M2 F87

  1. Screw out knurled screw (1) in such a way to make room for the amount of refrigerant oil to be filled into the special tool 2 286 910 , if necessary.
  2. Unscrew lid (2).
  3. Fill in refrigerant oil from measuring cup into special tool 2 286 910 via opening of lid (2).
  4. Screw hose (4) on lid (2) until hand-tight.
  5. Screw lid (2) with hose (4) on special tool 2 286 910.
  6. Rotate knurled screw (1) until refrigerant oil slightly emerges from opening (3).
  7. Screw low pressure quick-release coupling (5) on hose (4).

Tightening torque: _10 Nm

Filling refrigerant oil by means of injection BMW M2 F87

  1. If necessary, turn the screw (1) on the low-pressure quick-release coupling (2) anticlockwise.
  2. Connect low pressure quick-release coupling (2) with low pressure connection on vehicle and tighten screw (1) in clockwise direction.
  3. Screw in knurled screw (3) completely until reaching limit position.
  4. Release screw (1) in counterclockwise direction and remove low pressure quickrelease coupling (2) from low pressure connection on vehicle.
  5. BMW I01 with heat pump: Plug in the connector pulled off before filling procedure.
  6. Delete the fault memory.
