Refrigerant Oil Capacities In Refrigerant Circuits For Refrigerant R134A, Pr Number KK1

Depending on the time period of production and the engine, the compressor construction type may vary. Refer to the Parts Information.
Depending on the A/C compressor type, different refrigerant oil capacities may be designated for the refrigerant circuit. Refer to the Parts Information.
Different refrigerant oils are used depending on the manufacturer of the A/C compressor. Refer to Parts Information.
Refer to APPROVED REFRIGERANT OILS AND REFRIGERANT OIL CAPACITIES FOR REFRIGERANT R134A, PR NUMBER KK1

The mechanically driven replacement compressor is already filled with a specific amount of refrigerant oil (currently 110 +/ - 10 cm³ depending on the A/C compressor), this refrigerant oil quantity corresponds to the oil quantity designated for this refrigerant circuit on vehicles with one evaporator. On vehicles with two evaporators, a larger refrigerant oil quantity is required in the refrigerant circuit (currently an additional 30 cm³ ) because of the longer refrigerant lines and the second evaporator. If the compressor is replaced after cleaning the refrigerant circuit, this refrigerant oil quantity must therefore be added to the refrigerant circuit (for example, into opened lines or component connections) in vehicles with two evaporators. If A/C compressor is replaced without having to clean the refrigerant circuit, the refrigerant oil quantity in the new A/C compressor to be installed must be adjusted to the oil quantity poured out of the old A/C compressor. Refer to Refrigerant Circuit Components, Replacing or COMPONENTS, REPLACING .
These A/C compressors are available as replacement parts with different oil fill capacities, therefore pay attention to the exact part number. Refer to the Parts Information.
A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
On the Audi Q7 e-tron there are differences to the other vehicles additional components installed in the refrigerant circuit. Refer to SYSTEM OVERVIEW - REFRIGERANT CIRCUIT .
