The Audi creative pitch is approaching the end game with three agencies remaining in play, AdNews understands.
Incumbent Rapp is on the shortlist. The other two agencies understood to be in the running are 303Lowe and Host.
News of the pitch, which is being managed by Trinity P3 emerged last month.
Other agencies on the initial shortlist were thought to include the Monkeys and The Hallway.
The winner of the business is likely to be announced next month.
Neither digital nor media accounts are affected.
Audi is owned by Volkswagen Group. Volkswagen's creative business is globally aligned with DDB Group, Rapp's parent network.
