Condenser
Condenser
• Condenser is available in different versions, depending on version of vehicle.
• In contrast to vehicles with other engines, vehicles with the 10-cyl. TFSI engine (Audi RS6) have a condenser with a smaller interior volume installed. For this reason, the refrigerant fill volume is slightly less in a 10-cyl. TFSI engine than in other engines.
• Removed condenser contains refrigerant oil which must be restored to the refrigerant system.
• The radiator and condenser may have small indentations on the fins even when installed correctly. It is not damage. Do not replace the radiator or condenser because of those small indentations.
Removing
- Drain the refrigerant circuit.
- Remove the front bumper cover and the bumper cover holder- A.
- Remove the air ducts - B - and - C -.
• Remove the screws - arrows - to remove the air ducts.
- Remove the top water cooler (e.g. for Audi RS6, not present in all versions) => Engine Mechanical 10.
- Additionally for the Audi RS6, remove the right coolant hose by loosening clamp - 1 -.
- Remove air ducts - 2 - and - 3 - (e.g. for Audi RS6, not available in all versions).
• Item - 4 - shows the electrical connection to the A/C Pressure/Temperature Sensor (G395)
- If necessary, remove the power steering oil cooler - D - from the front end module (not necessary for all versions).
- Disconnect the connector - A - from the A/C Pressure/Temperature Sensor (G395) - B -.
- Disconnect refrigerant lines from condenser => [ Refrigerant Lines, Disconnecting from Condenser and Connecting ] Refrigerant Lines, Disconnecting from Condenser and Connecting.
- If you want to replace the condenser, remove the A/C Pressure/Temperature Sensor (G395) - B - => [ A/C Pressure/Temperature Sensor ] A/C Pressure/Temperature Sensor.
- Remove bolts - C -.
- Remove the condenser - D -.
• A condenser of a slightly smaller size is installed in the Audi RS6; remove the screw here - arrows -.
Installing
• Condenser is available in different versions, depending on version of vehicle.
• In contrast to vehicles with other engines, vehicles with the 10-cyl. TFSI engine (Audi RS6) have a condenser with a smaller interior volume installed. For this reason, the refrigerant fill volume is slightly less in a 10-cyl. TFSI engine than in other engines.
• Removed condenser contains refrigerant oil which must be restored to the refrigerant system.
Installation is carried out in the reverse order, when doing this note the following:
• Torque for bolts - arrows -: Condenser to radiator - 5 Nm
- Install the condenser on the chiller
- Install refrigerant lines on the condenser => [ Refrigerant Lines, Disconnecting from Condenser and Connecting ] Refrigerant Lines, Disconnecting from Condenser and Connecting.
- Following attachment, check routing of refrigerant pipes. They must be inserted in holders provided and not make contact with other components.
- Reinstall removed components (air ducts, water and oil coolers, etc.) in reverse order of removal.
- Install the front bumper (and all other components that were removed).
- Evacuate and refrigerant circuit after assembly and refill.
- Fill coolant and bleed coolant circuit (e.g. for Audi RS6).
- Check the DTC memory for the Climatronic Control Module (J255) A/C control head and erase any faults displayed if necessary.
- Operate the A/C system after filling the refrigerant circuit => [ A/C System, Operating after Filling Refrigerant Circuit ] A/C System, Operating after Filling Refrigerant Circuit
