Exterior Elements, Set of Elements (Part 2) (Audi A4 B8)

1. Refrigerant line with internal heat exchanger: in this line, there is a liquid warm refrigerant (on the pressure side) gives off energy to the cold vaporous refrigerant (on the low pressure side), thereby increasing the efficiency of the climate control system.
2. Expansion valve.
3. Coolant pipes to the heating heat exchanger in the air conditioner.
4. Service connection in the low-pressure circuit: for measuring and emptying the refrigerant circuit; cap with seal, wrap tightly; different versions (with primary valve. seals or nipples) depending on the refrigerant line, distinctive features.
5. Quick release coupling for refrigerant line on low pressure side.
6. Service connector in the high-pressure circuit: for measuring, emptying and filling the refrigerant circuit; cap with seal, wrap tightly; different versions (with primary valve. seals or nipples) depending on the refrigerant line, distinctive features.
7. Quick release coupling for refrigerant line on high pressure side.
8. Dryer reservoir: remove only when the air conditioning circuit is empty, and deliver the vehicle to a workshop that has the necessary equipment and trained, qualified personnel; the tank is installed directly on the condenser. Depending on the design of the condenser, the receiver-dryer can be installed or built into the condenser.
9. Condenser: remove only when the air conditioning circuit is empty.
10. Temperature sensor. and refrigerant pressure "G395".
11. Air conditioning compressor. installations with mech. drive: remove the compressor from the mount and reinstall it (for vehicles with a 4-cylinder engine) engine and 6-cyl. TDI engine. For vehicles with a 6-cyl. gasoline FSI engine, the compressor can be removed from the bracket only after draining the refrigerant from the circuit. At the beginning of production, compressors from Denso are installed (type 6 SEU 14 for vehicles with 4-cyl. and 6-cyl. FSI engines). Perhaps compressors from other manufacturers will be installed later.
12. Compressor regulating valve "N280". Installed on vehicles with an air conditioning compressor with mechanical. drive.
