93 e-tron GT: converting high-voltage battery charger from 22kW to 11 kW Release date: Aug 19, 2025

Condition

Customer states:

Complaints on charging / DTC.

Workshop findings:

According to a TSB/Guided Fault Finding, the high-voltage battery charger must be replaced.

There are no 22 kW high-voltage battery chargers available in the electronic parts catalogue => ETKA.

Technical Background

The previous 22 kW high-voltage battery charger (OBC) for the e-tron GT is no longer available. As such, an 11 kW

high-voltage battery charger (OBC) must be used if a replacement battery charger is required.

Production Solution

Not applicable.

Service
Try to reproduce the customer complaint (based on the description/cause of the issue), so that it can be
clearly assigned to this TSB. The following repair must only be carried out if all the criteria (model/type,
chassis number, engine/motor and gearbox code, PR number(s), part number, software version, code
etc.) apply exactly. Otherwise, this solution will not eliminate the problem and repeat repairs may be
necessary. In such a case, we may reject the warranty claim and charge back the cost of the parts.

If a replacement is required, the 22 kW high-voltage battery charger must be replaced with an 11 kW high-voltage

battery charger. To do so, proceed as follows:

1, Remove 22 kW high-voltage battery charger according to the Workshop Manual

Remove charging unit for high-voltage battery — Electric drive motor O0EG; Rep.Gr. 93 ; Charging unit for high-

voltage battery; Removing and installing charging unit 1 for high-voltage battery AX4

2. Install new 11 kW high-voltage battery charger according to the Workshop Manual

The brackets must be modified to install the 11 kW high-voltage battery charger:

a) Modify the bracket of the 22 kW high-voltage battery charger to fit the 11 kW high-voltage battery charger

Follow the instructions in the Workshop Manual Charging unit for high-voltage battery > Electric drive motor OEG;

Rep.Gr. 93 ; Charging unit for high-voltage battery; Removing and installing bracket for charging unit 1 for high-

voltage battery AX4.,

Both brackets of the 22 kW high-voltage battery charger (position 1) are removed (see following image).

Fir one of the two previously removed brackets at position 1 (see following image) on the new 11 kW high-voltage
battery charger using the new shorter (M6x18) bolts (see position 2). The tightening torque is 8 Nm.

3. Install the 11 kW high-voltage battery charger according to the Workshop Manual
Install charging unit for high-voltage battery > Electric drive motor OEG; Rep.Gr. 93 ; Charging unit for high-voltage
battery; Removing and installing charging unit 1 for high-voltage battery AX4.
4. Adapt the 11 kW high-voltage battery charger and flash SVM code to change PR no.: SVM code: C6A018
Applies to vehicles with high-voltage components:
To prevent the high-voltage battery from charging during the software update, the high-voltage charging cable on
vehicles with high-voltage components must be unplugged BEFORE the SVM code is entered.
Please note that charging the high-voltage battery during a software update can cause damage to the high-voltage
components.
Please adapt the new 11 kW high-voltage battery charger and run SVM code C6A018.

It is recommended to charge the vehicle using AC after completing the diagnostic session. If this charging process is
completed without any complaints, the vehicle can be returned to the customer.
If you require any assistance when working with the diagnostic tester, please refer to TSB 2011732. The
procedure for contacting product support can also be found in this TSB.
