Note
♦
The version of the reservoir on the Audi A3 and the Audi TT
will different depending on the manufacturer of the condenser.
An Audi TT with a 5-cylinder engine has a condenser in a dif‐
ferent version than on a model with a 4- or 6-cylinder engine.
The reservoir is, for example, inside the condenser. If the in‐
tegrated reservoir has a dryer cartridge, which is no longer
available as a single part. If there are complaints, then it is
necessary to replace the complete condenser. Refer to the
Electronic Parts Catalog and ⇒ Heating, Ventilation and Air
Conditioning; Rep. Gr. 87 ; Removal and Installation .
♦
If the reservoir / dryer cartridge is integrated in the condensor,
then they cannot be replaced individually or are not available
as a single part, and the condenser must be replaced. Refer
to ⇒ Heating, Ventilation and Air Conditioning; Rep. Gr. 87 ;
Removal and Installation and Electronic Parts Catalog (ET‐
KA).
