Process 1: Adapt cell capacities of high-voltage battery:
Adapt cell capacities of high-voltage battery as specified in the attachment
“Anleitung_Zellkapazitaten_anlernen_im_Service_VST”.
Process 2: Check event memory entries in hybrid battery management control unit (diagnostic address
008C) and adaptation status of cell capacities of high-voltage battery:
If event memory entry POBBDO0 is no longer displayed after Process 1, and if the adaption status of the high-
voltage battery cell capacities is OK according to Guided fault finding (test plan 008C — Check adaption status of cell
capacities), the measure ends here, the vehicle can be returned to the customer.
If the event memory entry POBBD00 still appears, please create a Web ticket with the Technical
Assistance Center (TAC). Please write the number of this TSB: 2075721 in the field for additional
information on workshop findings. This allows the internal department to identify the connection to this
TSB quickly.
- TAC will contact you as soon as possible and provide further information.
