Odors in Vehicles with A/C System

Odors from the A/C system (the heater) can come from various sources. Only a portion of these odors come from the A/C unit evaporator and can be corrected by cleaning the evaporator.

  Note

There is also an evaporator installed in the heater on the Audi Q3, but it does not have a function. If odors are originating at the evaporator installed in the heater, clean the heater (the evaporator) the same way as the Air Conditioning (A/C) unit on vehicles with an A/C system.

  Note

  • The odor can only be removed by cleaning with the Ultrasound A/C Cleaner -VAS6189B- if it originates in the evaporator.
  • Numerous procedures varying in their application and effect are available on the market for cleaning the evaporator. Audi, for example, has currently tested and approved cleaning the evaporator using the Ultrasound A/C Cleaner -VAS6189B-. Additional information for Audi tested and approved instruments can be found, for example, in "Audi ServiceNet" (see Table).
  • The procedures below show how to access the "Audi ServiceNet" in Germany. In other countries, the "Cleaning the A/C system" option can be found, for example, in the submenu "Original Parts". For instructions on "Cleaning the A/C system", follow the instructions in the "Audi ServiceNet".
