Capacities for Audi Q7 (4L_), from MY 2006

Features of the refrigerant system:

Vehicle type Production period Total quantity of oil in refrigerant circuit in cm(1) Quantity of refrigerant oil in replacement compressor in cm(1) Differing features of this refrigerant circuit
Audi Q7 (4L_) From 02/2006      
  • Vehicle with one evaporator
  140, 150 or 160+ 15 / - 10 (depending on the installed A/C compressor)
  • 140 + / - 10 (A/C compressor for a vehicle with a 6-cylinder TDI engine or with a 12-cylinder engine)
  • 150 + / - 10 (A/C compressor for a vehicle with an 8-cylinder engine or with a 6-cylinder 3.2L FSI engine)
  • 160 + / - 10 (A/C compressor for a vehicle with a 6-cylinder 3.6L FSI engine)
  • One evaporator
  • Compressor type "6 SEU 14" or "7 SEU 16" (see notes below)
  • Vehicle with two evaporators
  240, 250 or 260 + 15 / - 10 (depending on installed A/C compressor, refrigerant oil quantity in A/C compressor plus 100)
  • Two evaporators (pay attention to the notes below)
(1) The replacement compressor is already filled with a specific refrigerant oil quantity (currently 140, 150 or 160 ± 10 cm , 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 100 cm ) 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 the compressor is replaced without having to clean the refrigerant circuit, the refrigerant oil quantity in the new compressor to be installed must be adjusted to the oil quantity poured out of the old compressor. Refer to Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .
NOTE:

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.

The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor (with or without an oil separator on the high pressure connection) or to the design of the refrigerant circuit if the A/C compressors are have the identical design. Pay attention to the different capacities. Too much oil in the circuit leads to higher pressures and reduces cooling output of the system. Too little oil may lead to lubrication problems in the compressor.

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
