2.14 Air Guide In Air Distribution Housing
Note
♦
To illustrate air guide in the air distribution housing, it is shown
in the form of sectional views “A“ -“A“ and “B“- “B“.
♦
On the Audi TT with A/C system, both motors for left and right
temperature doors are controlled via one characteristics
curve, depending on the programmed end stops (only one
temperature setting on the Climatronic control module -
J255- ).
♦
Depending on the measured temperatures, the calculated
sunlight intensity and setting on Climatronic control module,
the calculated specified outflow temperature and therefore,
the specified position of the temperature doors, may be differ‐
ent for the left and right side.
♦
On the Audi TT with A/C (heating only), only one temperature
door motor is installed. Both temperature doors for the left and
right sides are connected via a shaft and moved together by
the Left Temperature door Motor -V158- .
♦
Vehicles without A/C do not have a temperature sensor. The
outflow temperature is not controlled. The Left Temperature
Door Motor -V158- is placed in a position calculated according
to the temperature setting and the programmed motor stop
values by the Climatronic control module.
