The basic functions of the air conditioner in
the Audi A4 are based on the Audi A6 system
and includes the following features:
– Air-side separation for driver’s and passen-
ger’s side.
– The heat exchanger can be replaced with-
out removing the air conditioner.
– The PTC additional heater element for die-
sel mechanical units can also be replaced
without removing the unit.
– All control motors and potentiometers are
easily accessible and replaceable.
– Connecting hose from air conditioner to
glove compartment for supplying the glove
compartment cooler (optional).
(in vehicles without glove compartment
cooling, the connection is sealed with a
rubber plug).
– Modified fresh air blower for passenger
compartment (description, see section:
Fresh air blower/electronically controlled
fresh air blower, on page 81).

compartment cooler
Glove compartment cooling
The cooler fills the entire space of the glove
compartment. It can, for instance, hold two
bottles with a volume of 0.25 and 0.7 litres.
The cold air supply is achieved via a connect-
ing hose from the air conditioner unit.
The hose is fitted with a rotary slide for cold
air regulation.
Two examples give an impression of its per-
formance:
– Cooling of the cooler contents from
approx. +30 °C to approx. +16 °C within one
hour and
– after switching off the cold air supply,
warming up by approx. +4 °C per hour at an
ambient temperature of approx.
+30 seconds and exposure to the sun.
