For the Audi A4 B9 (A4 Limousine, A4 Avant, A4 allroad quattro, S4, RS4 Avant; chassis B9, 8W; model years 2015-2024) our catalogue lists 67 features in 12 categories. Below you see per category what we can switch on or retrofit.
Each feature shows how certain we are: “likely possible” means several independent sources confirm it; “checked at diagnosis” means it differs from car to car. Final compatibility is always confirmed at the diagnosis of your car.
Seven Tuning works in Rotterdam and Waddinxveen: the workshop is in Waddinxveen and serves Rotterdam and the surrounding area. Remote coding works anywhere in the Netherlands and abroad, when the job allows it.

We agree the exact setting with you in the workshop.
