Right Curtain Airbag (Roof Side Curtain / Sideguard) – 4K8880742E

Original right-side curtain airbag (side curtain protecting the front and rear passenger's head along the right roofline), designed for Audi A7 Sportback, S7 and RS7 (4K / 4K8 generation) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI), 2.0 TFSI (40/45 TFSI), TDI diesel engines, and top-spec 2.9 TFSI (S7) and 4.0 V8 TFSI (RS7) models, based on the modular longitudinal MLBevo platform.

Original VAG passive safety system (SRS / Airbag) component. It consists of an original pyrotechnic inflator (gas generator), multi-chamber gas-tight fabric, and integrated factory mounts, mounting straps, and mounting plates. It protects the head and cervical spine of passengers on the right side of the vehicle during a side impact or rollover, inflating in a fraction of a second along the entire length of the right roofline – from the A-pillar, through the B-pillar, to the C-pillar.

Fitment guarantee and VIN verification

Each curtain airbag undergoes a rigorous inspection of the gas generator's condition, checking for fabric tears and ensuring the factory roll remains intact before being packed for secure transport.

Fitment / installation note: The initial designation 4K8 (safety system group 880) along with the paired ending 742 clearly defines the right side of the curtain, with a geometry precisely fitted to the sloping roofline of the Audi A7 Sportback body (curtains from A6 C8 sedan or estate models are not interchangeable due to different C/D-pillar profiles). After installing a functional curtain, the crash data must be cleared from the airbag control unit (module 15 – Airbag). Using an original OEM curtain guarantees factory igniter resistance, no errors in the SRS system, and full passenger protection effectiveness. Before purchasing, we recommend comparing the OE number on the pyrotechnic inflator label or verifying it using the vehicle's VIN.
