Filling of the refrigerant oil by injection (530e PHEV 2018-2022, 530e xDrive PHEV 2018-2022)

Special tools required:

IMPORTANT: This procedure is only applicable to:

Countries, in which BMW i vehicles or hybrid vehicles are delivered with R134a refrigerant.
Workshops in these countries that do not have a separate A/C service station for BMW i vehicles or hybrid vehicles.
If a BMW i vehicle or a hybrid vehicle (refrigerant R134a, refrigerant oil Sanden SP-A2) is to be filled with an A/C service station for R134a and the storage tank of this A/C service station is filled with the refrigerant oil ND-8.

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

EVACUATE REFRIGERANT circuit and fill with refrigerant.
(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 coolant oil level to be filled in:
Parts of refrigerant circuit were not replaced:

Coolant oil level to be filled in =

Coolant oil level drawn off by means of A/C service station + 4 ml addition (for volume of the hose)

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

Coolant oil level to be filled in =

Coolant oil level drawn off by means of A/C service station + extra amount for new part +

4 ml addition (for volume of the hose)

When replacing the air conditioning compressor:

Coolant oil level to be filled in =

Coolant oil level drawn off by means of A/C service station +

Coolant oil level determined from previous air conditioning compressor +

4 ml addition (for volume of the hose)

Pour coolant oil amount to be refilled into a clean measuring cup.

Screw out knurled screw (1) so as to make room for the coolant oil amount to be filled into the special tool 2 286 910, if necessary.
Unscrew lid (2).
Fill in refrigerant oil from measuring cup into special tool 2 286 910 via opening of lid (2).
Screw hose (4) on lid (2) until hand-tight.
Screw lid (2) with hose (4) on special tool 2 286 910.
Rotate knurled screw (1) until refrigerant oil slightly emerges from opening (3).

Screw low pressure quick-release coupling (5) on hose (4).

Tightening torque: 10 Nm

If necessary, turn the screw (1) on the quick-release coupling for low pressure (2) counterclockwise.
Connect quick-release coupling for low pressure (2) with low pressure connection on vehicle and tighten screw (1) in clockwise direction.
Screw in knurled screw (3) completely until reaching stop.
Turn screw (1) counterclockwise. Remove the quick-release coupling for low pressure (2) from the low pressure connection on the vehicle.
Delete the fault memory.
