Climate control
Introduction
Heating / air conditioning system
versions
Two heating and air conditioning systems are specified for
the 2015 Audi A3 depending on model.

•
•

manually controlled air conditioning system
Climatronic

The Climatronic system has a moisture and enthalpy
control system. The moisture control system is used to
detect windshield fogging.
Enthalpy is a measure of the energy content in the air
conditioning system. Air conditioning efficiency is ensured
by precision control of the fresh air to recirculated air ratio
inside the vehicle.

Operation
The two versions differ from one another with respect to
their equipment specification. All versions are optionally
available with seat heater control buttons. The seat heater
is a three-stage system and the selected heating level is
indicated by an LED in the respective button.

Both versions have a dust and pollen filter. The Climatronic
system has an activated charcoal dust and pollen filter. In
combination with the Air Quality Sensor, the activated
charcoal component in the filter works to reduce pollutant
emissions in the fresh air inside the vehicle.

Some of the rotary controls in both versions have multiple
functions, such as for turning cooling or automatic air
conditioning ON and OFF.

The dust and pollen filter can be replaced through the open
glove compartment.

The table shows an overview of the main functions of the individual versions:

Infotainment
In response to the speed at which the development cycles
for information and entertainment systems occur, the
automotive industry has had to shorten its development
cycles as well. Keeping up to date with the latest advances
is a growing challenge for car makers.
To meet this challenge, the Volkswagen Group has introduced the Modular Infotainment Platform (MIB).
Central to the development of the MIB, Information Electronics Control Module 1, has been re-designed as a
modular component. The control module architecture

allows the hardware to be easily and economically updated
so that it always incorporates the latest technological
advances.
An important component is the graphics processor made by
market-leader Nvidia, with whom Audi enjoys a very successful business relationship. The latest Nvidia processors
will continue to be used in Audi vehicles in the future. The
new platform means that it will be possible to use the
same central processing units across the entire Group. So,
in the future it will be possible to run brand specific variants on four standardized hardware platforms.

Overview of versions
In the North American market, the following versions of
the MIB will be available on the 2015 Audi A3:

•
•

Standard MIB - MMI radio
High-spec MIB
•
MMI navigation plus
•
MMI navigation plus with Audi connect

On a world-wide basis, Audi offers three main configuration
levels for the Modular Infotainment Platform:

•
•
•

Entry MIB
Standard MIB
High-spec MIB

Each of the main configurations has its own sub-configurations depending on the optional equipment installed. All of
the MIB configurations use Information Electronics Control
Module 1 as the central processing unit.

Standard MIB
In terms of functionality and specifications, the Standard
MIB is comparable with the RMC Radio Media Center. This
will be marketed in the North American region as Audi MMI®
radio.

The module for the Standard MIB always has a MOST bus
connection. If no optional equipment requiring MOST data
transfer is installed, the MOST connection is unused.

Standard MIB (MMI® radio)
MMI® radio is based on the Standard MIB and offers the
following features:

•
•
•
•
•
•
•
•
•
•

Radio with phase diversity module, FM twin tuner (frequency modulation) and AM tuner (amplitude modulation)

High spec MIB with navigation
The High-spec MIB is the current high-end version of the
Modular Infotainment Platform. Two versions will be available in the North American market. In both versions, Information Electronics Control Module 1 has a MOST bus connection. If no other optional equipment requiring a MOST
connection is installed on the vehicle, the connection is not
used.
The High-spec MIB represents a consistent step forward
from the 3G + MMI and features new 3D screen views and
SSD (solid state drive).

As mentioned earlier, Information Electronics Control
Module 1 incorporates an Nvidia Tegra processor. It is a
multi-core processor that generates ultra-high resolution
graphics as well as offering faster rendering of current audio
and video formats. The Tegra chip requires substantially less
energy than previous multimedia processors and fits perfectly with the Audi efficiency philosophy.
The Tegra chip can display entire cityscapes in three-dimensional views – the driver sees the street that he is driving
along in photo-realistic quality.
The High-spec MIB is also the only version of the MIB that
can play video files directly.
