Official summary
Due to a process fault, the gearbox was filled with ATF fluid containing sulphur on Audi vehicles with multritronic manufactured within a specific period. As a result, a copper sulphide layer may form on the conductor tracks of the gearbox control unit and cause electrical faults. Drain and flush the gearbox and replace the multitronic unit.

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.
