It will mark the Supercars legend's fourth appearance in the front-wheel-drive series, after he made a trio of round starts in a Melbourne Performance Centre Audi back in 2019.
That included a race win and two second places at The Bend, while he also took pole for the season-opener at Albert Park in 2020 that went on to be cancelled.
Tander will be teamed up with series leader Chaz Mostert at the MPC Audi squad.
Liam McAdam will also join the Audi line-up, as Carrera Cup regular Duvashen Padayachee prepares for his first TCR start with the HMO Customer Racing Hyundai squad.
