Customer Concern: Reduced electric vehicle range. or The customer is requesting information on the State of Health (SOH) of the high-voltage battery (e.g., in order to sell the vehicle). Workshop Findings: The customer concern can be reproduced. No relevant DTCs (active/static) indicating concerns with the high-voltage battery are present in the Hybrid battery management -J840- (diagnostic address 008C). If there are DTCs (active/static) present in the Hybrid battery management -J840- (diagnostic address 008C), then this bulletin does not apply! The appropriate Guided Fault Finding (GFF) test plan(s) should be followed and resolved before any determination of the remaining battery capacity is performed.

Technical Service Bulletin 93-23-08 - Determination of HV-Battery Health, Remaining Capacity Transaction No: 2071535/2 Release date: 12/7/2023 Technical Background Through normal usage over time, the high-voltage batteries of electric vehicles are subject to various aging effects, which could lead to a reduction of the overall battery capacity (energy density). This agerelated reduction of the battery capacity is normal. Production Solution Not applicable. Service If a range complaint is presented by the customer, Technical Service Bulletin 2071494 should be reviewed before carrying out the procedures outlined below. To determine the remaining battery capacity of the high-voltage battery, there are three different test plans available in Guided Fault Finding (GFF). The significant differences of the test plans are explained in the following table: Battery Health Status (BHS) Battery Health Certificate (BHC) Battery Health Quicktest (BHQ) Duration About 25 to 50 time units (TU) About 50 time units (TU) of productive tester time. Total duration up to 750 time units (TU) About 25 to 50 time units (TU) Output Direction decision, no decimal value in % Decimal value in % Decimal value in % Measuring tolerance ± 10 percentage points ± 1-2 percentage points ± 10 percentage points (without qualified measured value) ± 5 percentage points (with qualified measured value) Page 2 of 7 Plus attachment © 2023 Volkswagen Group of America, Inc.

Technical Service Bulletin Transaction No: 2071535/2 Release date: 12/7/2023 93-23-08 - Determination of HV-Battery Health, Remaining Capacity Warranty Accounting Options Warranty with justified customer complaint Warranty with justified customer complaint Only used for customer pay (non-warranty) OR Customer pay (non-warranty) Note: For e-Golf vehicles, “sedan” must be chosen and not “wagon” when selecting vehicle options at the start of GFF diagnosis, to ensure that the correct test plans are visible. These three test plans are part of a singular test, “detect battery capacity status”, which can be found within Guided Fault Finding (GFF) under the following path: > Test plan > Select self-test > 008C – Detect battery capacity status To be covered under warranty, only the following test plans may be used for the check of the remaining battery capacity of the high-voltage battery: 1. Battery Health Status (BHS) – Required. 2. Battery Health Certificate (BHC) – Only as necessary based on BHS results. At the customer’s request (non-warranty), either of the following test plans may be used to check the remaining battery capacity of the high-voltage battery: Battery Health QuickTest (BHQ) Battery Health Certificate (BHC) Checking the remaining battery capacity of the high-voltage battery at the customer’s request (e.g. without a warrantable customer complaint) is not covered under warranty policy!

Technical Service Bulletin 93-23-08 - Determination of HV-Battery Health, Remaining Capacity Transaction No: 2071535/2 Release date: 12/7/2023 To check the remaining battery capacity of the high-voltage battery as part of the warranty: Note the information in theto this bulletin. The customer can positively influence the test procedure by properly pre-conditioning the high-voltage battery according to the instructions within. By performing this pre-conditioning, a qualified measured value can be generated, which can improve the measuring tolerance. In the case of the long measurement, if required, they can also significantly reduce the duration of a workshop visit, due to the required battery discharge at the start of the check. 1. Carry out the “Battery Health Status” (BHS) portion of the “determine battery capacity status” test plan through Guided Fault Finding (GFF). IMPORTANT: Save a copy of the test plan result screen in “.pdf” format by using the “print” function in GFF. This printed result may be required for documentation through warranty! “Battery capacity ≥ 70 %”: If the result of the remaining battery capacity check is equal to or greater than 70%, it will be indicated by an “X” in this section (there is no decimal value output). “Long measurement recommended”: If the GFF test plan recommends no further testing, it will be symbolized by a “-“ in this section. In this case the high-voltage battery remaining capacity is OK in the sense of warranty; do not perform any further actions from this bulletin. “Long measurement recommended”: If the GFF test plan recommends a longer measurement to determine the remaining battery capacity, it will be symbolized with an “X” in this section. In this case the BHS test was not sufficient to determine if the vehicle is above or below the warranty limit; therefore proceed to step 2. 2. If the long measurement was recommended by the BHS test in step 1, then carry out the “Battery Health Certificate” (BHC) portion of the “determine battery capacity status” test plan through Guided Fault Finding (GFF). IMPORTANT: Save a copy of the test plan result screen in “.pdf” format by using the “print” function in GFF. This printed result may be required for documentation through warranty! There is an output of a decimal percentage value of the remaining battery capacity. If the result of the remaining battery capacity check is equal to or greater than 70%, then the highvoltage battery is OK in the sense of warranty; do not perform any further actions from this bulletin. If the result of the remaining battery capacity check is less than 70%, check the warranty conditions applicable to the vehicle to determine whether a warranty case applies. If there is an applicable warranty of the high-voltage battery, proceed to step 3. Page 4 of 7 Plus attachment © 2023 Volkswagen Group of America, Inc. All rights reserved.

If the remaining battery capacity was determined to be less than 70% by the BHC test in step 2, then contact the Volkswagen Group TAC for next steps. Provide the complete GFF log as well as the “.pdf” copies of both the BHS test and the BHC test when opening a TAC ticket. The appropriate warranty repair direction will be provided through the TAC ticket. The high-voltage battery cannot be replaced under warranty without first contacting the Volkswagen Group TAC as outlined in this document! To check the remaining battery capacity of the high-voltage battery as part of the customer’s request (not covered under warranty): Carry out either the “Battery Health Quick Test” (BHQ) or the “Battery Health Certificate” (BHC) portion of the “determine battery capacity status” test plan through Guided Fault Finding (GFF). Warranty The warranty information within this document only pertains to the testing required to determine the remaining capacity of the high-voltage battery! Any repairs to and replacement of the highvoltage battery, as determined through contact with the Volkswagen Group TAC, are outside the scope of this document. Please see the repair manual for any labor operations and special tools that may be required. Only the “Battery Health Status (BHS)” and “Battery Health Certificate (BHC)” checks can be claimed via warranty with a justified customer complaint. For checking the remaining battery capacity at the customer’s request, and for the “Battery Health Quicktest (BHQ)”, no warranty applies.
