Audi Q7: Overview - Attachments for Heater and A/C Unit and Air Intake Housing

Audi Q7 (4M) 2016-2024 Workshop Manual / Heating, Ventilation & Air Conditioning / Air Conditioning / Rear Heater and A/C Unit / Overview - Attachments for Heater and A/C Unit and Air Intake Housing

General information for "Mid"/"Mix" and "High" A/C System

  Caution

Interchange of the wire connections to the temperature sensors or the connectors at the adjustment motors results in problems regarding the regulation of the A/C system.

A/C system malfunctions in the case of interchanged control motors and/or connectors. Refer to → Chapter "Main Wiring Diagram for A/C System Actuators".

  • Interchanged connectors at the adjustment motors or the temperature sensors are not identified as malfunctions by the Rear A/C Display Control Head -E265-.
  • Prior to disconnecting connectors or removing electrical components, clearly label them in order to rule out confusion.

  Note

  • Depending on vehicle equipment, there are different versions of the A/C system for the Audi Q7. Make sure to use the correct version and pay attention to the allocation of different components. Refer to → Chapter "A/C System Versions" and Parts Catalog.
  • Depending on the vehicle equipment either a rear heater and A/C unit (on a vehicle with a "High" A/C system), a rear air distribution housing (on a vehicle with a "Mid" or "Mix" A/C system) or only a rear air duct on a vehicle with a "Low" A/C system) are installed. Refer to → Chapter "Overview - Air Routing and Air Distribution in Vehicle Interior".
  • The Rear A/C Display Control Head -E265- is an optional equipment (for "Mid", "Mix", or "High" A/C system) different versions -A or B-. Refer to the Parts Catalog.
  • For the start of production only on vehicles with a "Mid", "Mix" or "High" A/C system a Rear A/C Display Control Head -E265- is installed.
