Debris can be dispersed throughout the refrigerant circuit after A/C component damage. In order to maintain A/C operating efficiency, it is important to flush the refrigerant circuit after A/C component repairs. Note: This bulletin must be read in its entirety before beginning repair. Technical Background In cases where an air conditioning system component (such as a compressor or other system component) has failed and debris from the compressor or component is circulated throughout the refrigerant circuit, the refrigerant circuit must be cleaned of any and all debris or damage to the replacement components will result. Production Solution No production change required. Page 1 of 18 © 2019 Volkswagen Group of America, Inc. All rights reserved.

Technical Service Bulletin 87-18-08 - Air Conditioning, Cleaning of the R1234yf Refrigerant Circuit (U.S. Only) Transaction No: 2049039/3 Release date: 5/28/2019 Service Tools Use the MAHLE R1234yf A/C Service Unit VAS581005 and the R1234yf Flush Kit RTI360831040 (Figure 1). Used for effective refrigerant handling and air conditioning circuit flushing after air conditioning component failure. Figure 1. The VAS581005 Air Conditioning Service System with Flushing Device. The VAS 6338/1 Adapter Set for Refrigerant Circuits along with an additional adapter VAS 6338/38 for the expansion valve bypass this kit, contains the adapters necessary to complete a thorough flush operation of a contaminated circuit. Elsa contains the technical information for each model regarding the necessary adapter applications and connections of the servicing station for the flush operation. See Heating, Ventilation & Air Conditioning >> Refrigerant R1234yf-Servicing >> 00 General Technical Data>> Refrigerant Circuit removing contaminates>> Refrigerant Circuit, Flushing with Refrigerant R1234yf in Elsa. All other refrigerant recovery, evacuation and recharge operations are performed using the usual procedure specified in Elsa. An operations manual will accompany each servicing station that will describe operation of the unit. Page 2 of 18 © 2019 Volkswagen Group of America, Inc. All rights reserved.

Technical Service Bulletin 87-18-08 - Air Conditioning, Cleaning of the R1234yf Refrigerant Circuit (U.S. Only) Transaction No: 2049039/3 Release date: 5/28/2019 Procedure Front A/C: 1. If an air conditioning component has been diagnosed as the root cause of the failure, and this particular component has been verified to have released debris through the circuit, continue with the flush procedure. 2. Switch the power to the servicing station ON and begin by recovering the refrigerant from the system through the normal service fittings. Note: For all compressor replacements it is mandatory to flush the system of all oil in the system. The replacement compressor comes with a full charge of oil for a complete A/C system. Tip: During the entire process avoid interrupting the power to the station. The station's internal memory will keep a log of all operations and can conveniently be recalled and printed. If the power is interrupted, the station will lose the memory of the process, and the oil volume recovered, oil volume added, refrigerant volume recovered, etc. will have to be manually determined. 3. Disconnect the service hoses from the AC service ports of the refrigerant circuit. The VAS 6338/1 adapters will be used to bypass the following: Compressor. Expansion Valve. Rear AC lines to rear AC unit (If Equipped) Rear AC unit Expansion Valve (If Equipped) Note: For models with receiver drier desiccant cartridge the desiccant cartridge must be removed for the flushing process. For vehicles where the receiver drier is located on the condenser and DOES NOT have a remove-able desiccant cartridge, the receiver drier must be left in the system and flushed through. After the flush procedure is complete replace the receiver drier or drier cartridge. 4. Installing the R1234yf Flush Kit RTI360831040 flush tank to the Mahle A/C Service Unit VAS581005 5. Remove Receiver Drier. Refer to Elsa Repair Manual. Note: For Atlas, the front bumper does not need to be removed as stated in the Elsa repair manual. When removing front grille ensure ignition is switched OFF and negative battery cable is disconnected before disconnecting the front distance regulation module.
