Condenser, Removing And Installing: Installing

Install in reverse order of removal and note the following:

-- There is refrigerant oil in the removed condenser that must be redelivered to the refrigerant circuit (with new condenser). Refer to Refrigerant Circuit Components, Replacing (R134a) or COMPONENTS, REPLACING (R1234yf) .

-- Install the refrigerant lines on the condenser. Refer to REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT CONDENSER .

-- Evacuate and charge the refrigerant circuit. Refer to Refrigerant Circuit (R134a) or Working with A/C Service Station (R1234ya) (1 of 2) or Working with A/C Service Station (R1234yf) (2 of 2) .

-- Install the remaining removed components.

-- Switch the ignition on.

-- On vehicles with a high-voltage system (Audi Q7 e-tron), initiate the basic setting of the A/C system through the Thermal Management Control Module -J1024- and activate the power-controlled valves using one of the routines stored there. "Charge/flush the refrigerant circuit stop routine" using the Vehicle Diagnostic Tester in the "Guided Fault Finding"  function.

-- Check the DTC memory for the Front A/C Display Control Head -E87- and, if necessary, delete any displayed errors using the Vehicle Diagnostic Tester in the "Guided Fault Finding"  function.

-- Start the A/C system after charging the refrigerant circuit. Refer to A/C SYSTEM, STARTING AFTER CHARGING REFRIGERANT CIRCUIT .
