Official summary
Certain GV60 (JW1 EV) and G90 (RS4) vehicles may exhibit an inability to perform Over the Air (OTA) software updates due to an internal logic error that prevents the updates from being completed properly. This bulletin provides instructions to perform a Data Connectivity Unit (DCU) software update to correct this condition.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
