TFU = Technical Follow Up.
It is a centralized Airbus database with reported technical issues, updated on a regular base with findings, interim actions, workarouds and final status.
I don't know how your organization is constructed, ask your flight technical dept or chief / engineering pilot,
they should know about it and also how to gain access to this documents (webbased AIRBUS WORLD and/or AIRMAN web),
or contact the
Airbus local customer support representative
I cannot post the relevant TFU myself because it depends on type variants and the software status of your aircraft.
