Rear Right Bumper Guide / Fender Side Guide – 4K8807890

Original side mounting bracket / rear bumper guide (mounting guide for attaching the rear bumper trim to the fender on the right side – passenger side), 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.

Factory-fit VAG bodywork load-bearing mounting component. Made of hardened engineering plastic (POM/PA) resistant to vibrations, road impacts, and extreme temperatures. Mounted on the edge of the rear right fender. Ensures precise, tight, and even closure of the rear bumper corner, providing factory-standard gap alignment between the bumper and the metal fender and rear light, and preventing the bumper from coming loose at highway speeds.

Fitment guarantee and VIN verification

Each guide undergoes a check of the condition of the guide tabs and a control of the geometry of the mounting seats before shipping.

Fitment / installation tip: The initial designation 4K8 (body group 807 – bumpers) specifies the contouring of the fender arch that is unique to the A7 Sportback body (it is not interchangeable with the A6 C8 sedan and estate). The small snap tabs of this bracket break off during even minor parking damage or when forcefully removing the bumper. A broken guide causes the bumper to sag and creates a visible, uneven gap under the light. The original OEM component guarantees a factory line and secure snap-fit without the need for gluing. Before purchasing, we recommend comparing the OE number on the part body or verifying it using the vehicle's VIN.
