NOTE:

The version of the receiver/dryer on the Audi Q2, Audi A3, Audi Q3 and Audi TT will differ depending on the manufacturer of the condenser. On some versions for example the receiver/dryer is integrated in the condenser. The integrated receiver/dryer has a dryer cartridge that is no longer available as a replacement part. If there is a complaint regarding a vehicle with a condenser with an integrated receiver/dryer, it may be necessary to replace the entire condenser after correcting the complaint. Refer to the Parts Information and REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB]

Condensers with an integrated receiver/dryer or dryer cartridge that cannot be replaced separately or is not available as a replacement part, the condenser must be replaced after flushing (with the dryer cartridge installed). Refer to REFRIGERANT CIRCUIT [For engine(s) CTUA, CAED, CREH, CEUC, CTGE, CREC, CYNB, CPNB] and the Parts Information.
