Summary
The 2015 Audi Q3 Introduction
Note
New sensors are delivered with a transport protection cover which must be removed prior to installation.
57
Refrigerant circuit
The refrigerant circuit of the Q3 is designed for R134a
refrigerant. The circuit is controlled by a six piston
compressor, A/C Compressor Regulating Valve N280 and
an expansion valve. The receiver/drier is mounted on the
condenser
and features a removable cartridge.
The high and low pressure service valves are located on the
right hand side of the engine compartment above the side
member.
High Pressure Sensor G65 sends its data by PWM signals to
Climatronic Control Module J255.

Air conditioner housing
The air conditioner housing of the has the following
features:
• A condensate drain that flows to the outside through
the center tunnel on the front passenger side.
• The passenger compartment heat exchanger can be
replaced without removing the instrument panel or

Networked components
A/C Control Module J301 communicates with Vehicle
Electrical System Control Module 1 J519 and Instrument
Cluster Control Module J285 via the CAN data bus.
The heated front seats are operated via Front Seat Heating
Control Module J774. J774 is wired directly to the J519 and
therefore does not communicated over the data bus.

Signal processing
In the Q3, virtually all sensor and actuator signals are read
and processed by the Climatronic Control Module. The
exceptions are: Outside Temperature Sensor G17 and
Humidity Sensor G355.
Instrument Cluster Control Module J285 processes the
temperature signal from G17. Its value is transmitted to
the Climatronic Control Module via the CAN bus.
60
Humidity Sensor G355 sends its data to Vehicle Electrical
System Control Module 1 J519 on a LIN bus. The data is
then transmitted to Climatronic Control Module over the
Convenience CAN bus.
Infotainment
Overview of versions
The Q3 will have two infotainment options available.
The standard equipment infotainment system features the
concert radio. The MMI Navigation plus system is optional.
The concert radio is based on the Radio Media Center (RMC)
