Refrigerant Lines, Disconnecting And Connecting At Condenser, Except RS Models: Removing
-- Turn off the ignition.
-- Discharge the refrigerant circuit. Refer to REFRIGERANT CIRCUIT .
Depending on the allocation of the service connection to the refrigerant line and vehicle version, it may be necessary to remove the left auxiliary reinforcement on the tower brace so that the A/C service station service coupling can be connected (for example, on the Audi Q5). Refer to SUSPENSION STRUT AND UPPER CONTROL ARM and REFRIGERANT CIRCUIT .
-- Remove the bolts (or clips) -1, 2, 3 and 5-. Refer to LOCK CARRIER .
-- Lift the cover -4- on the lock carrier and disengage it on the radiator grille. Refer to LOCK CARRIER .
-- Remove the bolt -B-.
-- Remove the refrigerant line -A- from the condenser.
-- Release the clips in direction of -A arrows- and remove the left air intake grille -1- in the lower part of the bumper cover in direction of -arrow B-. Refer to FRONT BUMPER .
-- Remove the bolt -B-.
-- Remove the refrigerant line -A- from the condenser.
If, for certain vehicles (for example, the Audi SQ5), the bolt -B- is not accessible with the lower left bumper cover removed (due to the bumper version), completely remove the bumper cover. Refer to FRONT BUMPER .
Seal open pipes and connections at condenser with suitable caps (to prevent ingress of dirt and moisture).
The Audi Q5 has a refrigerant line made up of two pieces; do not open the connections between both pieces to remove the condenser (it is possible, but not necessary).
If one piece of the refrigerant line on the Audi Q5 has to be replaced, then the same tightening specification for the bolt on the condenser connection applies to the bolt on the connection.
