Original Adjustable Tailgate Stop / Buffer – 8W9827239

Original factory-fit rear tailgate spacing buffer (rubber-spring positioning buffer for the tailgate – Anschlagpuffer für Heckklappe), designed for Audi A7 Sportback, S7 and RS7 (4K / 4K8 generation), as well as Audi A4 Avant (B9 / type 8W) and Audi A6 C8 (type 4K2 / 4K5 / 4KA) produced from 2018 to 2026, including models with 3.0 V6 TFSI (55 TFSI / 340 hp), 2.0 TFSI (40/45 TFSI), S7 and RS7 variants, and TDI diesel engines, based on the modular MLBevo longitudinal platform.

Original VAG group bodywork soundproofing and guiding component. It consists of a durable technical plastic housing, an internal spring-loaded latching mechanism (enabling precise extension adjustment), and a wear-resistant, weather-resistant vulcanized rubber (EPDM) head. It is responsible for the initial opening of the tailgate after the electric lock is released, cushioning the impact during closing, eliminating tailgate vibrations and rattling when driving over uneven surfaces, and perfectly aligning the tailgate panel with the wheel arches and rear sill.

Fitment guarantee and VIN verification

Every buffer undergoes a return spring stroke functionality test, adjustment latch check, and inspection of the condition of the front elastomer surface before shipping.

Fitment / installation tip: The initial designation 8W9 (tailgate group 827) defines the standardized buffer mechanism developed for the MLBevo platform. A worn or damaged internal buffer spring means that after pressing the button on the remote control or tailgate, the lock unlocks, but the tailgate does not pop open and relocks. A cut or missing buffer rubber leads to annoying metallic tailgate rattles over bumps and rubbing of the tailgate paint edges against the bumper. Thanks to the built-in adjustment, the buffer allows precise setting of the gaps and seal tension. Before purchasing, we recommend comparing the OE number stamped on the buffer flange or verifying it using the vehicle's VIN.
