Oil Distribution

WARNING: This page is about a different car, the 2017 Volkswagen Touareg, 2016 Volkswagen Touareg, and 2015 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

When the A/C system is being used, the refrigerant oil that was in the A/C compressor before switching on the A/C system for the first time is distributed throughout the entire refrigerant circuit.
Depending on the previous operating condition of the A/C system before switching it off, the ambient temperatures, etc., the distribution of the refrigerant oil in the refrigerant circuit varies. A general statement about the refrigerant oil distribution in the refrigerant circuit is therefore not possible. Pay attention to the information about the replacement of refrigerant circuit components. Refer to Components, Replacing or COMPONENTS, REPLACING .
