WARNING: This page does not describe the selected car, but rather 70 other vehicles, including the 2012 BMW Z4, 2012 BMW X6 M, 2012 BMW X6, 2012 BMW X5 M, and 2012 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
Especially for the refrigerant R134a (tetrafluorethane), a PAG refrigerant oil (polyalkylene glycol) had to be selected which ensures the lubrication of the compressor.
This oil may not be mixed with the refrigerant oil Sanden SP-A2!
This refrigerant oil is very hygroscopic and must only be exposed to air humidity for a very short period.
