Condenser HVAC: Service and Repair

NOTE: This procedure applies to both driver-side and passenger-side condensers.

Removal







1. Remove the cover above the heating/air-conditioning system.
2. Remove the refrigerant by suction using the service unit.
3. Completely remove the front spoiler. Remove the air guide to the condenser and pull off the electrical plug connection on the temperature sensor.
4. Undo the refrigerant line on the condenser. Immediately close connections and lines with plugs so that they are air-tight.
5. Undo the fastening screws (2 screws) from the condenser and pull the condenser to the side out of the holder.


Installation
1. Do not remove the plugs for the lines and condenser connection until shortly before installation.
2. Replace O-rings and wet the new rings with refrigerant oil.
3. Tightening torques:
Refrigerant lines M8 14 Nm (10.5 ftlb)
Condenser 4.0 ± 0.5 Nm (3.0 ± 0.5 ftlb)
Air guide 4.0 ± 0.5 Nm (3.0 ± 0.5 ftlb)

When loosening or tightening the M8 refrigerant lines on the condenser, always counter with a 21 mm open-ended wrench.

4. Determine the quantify of the refrigerant oil and fill up again with refrigerant oil (volume removed by suction + 20 cu.cm).


NOTE: Refrigerant oil removed from a previously run air-conditioning system may no longer be used (special-category waste).
