NOTE:
Depending on the condenser manufacturer, the receiver/dryer version for the Audi A4 (8K_) from MY 2008 varies. Refer to Refrigerant Circuit . The receiver/dryer may be attached to or integrated in the condenser, depending on the version of the condenser. The integrated receiver/dryer has a dryer cartridge that is no longer available as a replacement part. In the event there is a complaint on a vehicle with this condenser, the condenser must be completely replaced. Refer to the Parts Information.
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 and the Parts Information.
