Condition

• Certain Model Y vehicles built in Giga Berlin between September and December 2022 may suffer from contamination in the Supermanifold to Compressor A/C line, resulting in a potential premature failure of the A/C compressor.

Correction

• Inspect the Supermanifold to Compressor A/C line to determine the type of A/C line installed.
• If necessary, flush the HVAC case and replace the compressor, the supermanifold, and the A/C lines.

• NOTE: The time in the table above includes all technician touch time, but not all of the A/C machine flush time. Depending on the flush time, vehicles will occupy the workspace for 3 to 4.5 hours.
• NOTE: Make sure that coolant and refrigerant stock is replenished in time if this procedure is performed frequently.

Part Description

revisions listed or later, unless otherwise specified in the Parts Catalog.

Inspection

NOTE: Inspect the Supermanifold to Compressor A/C line to determine whether repairs are needed.

1. Remove the HEPA filter (refer to service manual procedure 18105401).
2. Check the location of the high-pressure charge port in the supermanifold to the compressor discharge line.
   • If the high-pressure charge port is located near the compressor (Figure 1), repairs are not necessary. Proceed with step 3 of this section to check the configuration and update the configuration if necessary.
   • If the high-pressure charge port is located near the supermanifold (Figure 2), skip to the section Replace A/C Components.
3. Reinstall the HEPA filter (refer to service manual procedure 18105401).
4. Connect a laptop with Toolbox 3 to the vehicle.
5. In Toolbox 3, click the Dashboards tab and select Infotainment Dashboard.
6. On the Infotainment Dashboard, make sure these values are as shown below, and modify them if necessary:
   • compressor Type: DENSO_11K_COP1_ENABLED
   • coolant Pump Type: DUAL_MIX
   • refrig AC Line Type: SAAA_LIMITED
7. Disconnect the laptop from the vehicle.
8. Use correction code S012318001.

Replace A/C Components

• CAUTION: Make sure to start the repair procedure with a recovery machine that has been inspected is within the valid certification period, and has a minimum of 6 kg of refrigerant.
• CAUTION: The recovery machine filter can be used for 10 full flushes. Mark the filter before each flush and replace the filter after 10 full flushes, as soon as it shows icing during the flush, or when the recovery machine displays an error (Error 09 on Waeco ASC 5500).
• CAUTION: Make sure to leave new parts sealed as long as possible, and immediately seal up all inlets and outlets of any part that has been removed, to prevent ingress of foreign debris.
• NOTE: Only perform this procedure after having determined that repairs are needed (refer to Inspection).

1. Replace the Compressor, the Supermanifold, and the A/C lines, and flush the HVAC case (refer to Service Manual procedure 18204012).
2. Use correction code S022318001.
