Air conditioning
Overview
The air conditioning system of the
Audi TT Coupé ‘07 is an improved version of the
system used in the Audi A3 ’04. The automatic air
conditioning system is configured as a single-zone
air conditioning system. The TT Coupé has only one
climate zone with no temperature differential
between the driver and front passenger sides.
The TT Roadster is available with a heating-only
system, in addition to the automatic air
conditioning system.
The TT vehicles with petrol engine have no auxiliary
heater and, therefore, no electrical PTC heater
element.
The Climatronic control unit J255 has a rotary knob
for temperature selection, but no digital display.
The system has an air recirculation function, which
can be activated either by the occupants or
automatically as soon as the "on" conditions for air
recirculation have been met.
The automatic air recirculation function by means of
an air quality sensor G238 was not implemented;
no air quality sensor G238 is fitted.
The fresh air intake duct temperature sensor G89 is
not fitted. Information on ambient temperature is
supplied only by the ambient temperature sensor
G17 via CAN data bus from the dash panel insert.
