Audi Q7: 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.
