Left Fender Cover / Windshield and Fender Corner Trim – 4K8820581

Original left front fender corner cover (triangular cover / trim strip for the gap between the fender, A-pillar and windshield – driver's 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, TDI engines and models with the S-Line styling package, based on the modular MLBevo longitudinal platform.

Original VAG body sealing and protective element. Made of hardened technical plastic combined with a flexible EPDM rubber sealing lip, resistant to UV radiation, extreme temperatures, car wash chemicals and aging processes. Mounted in the upper rear corner of the left fender, close to the base of the A-pillar and the lower corner of the windshield. It precisely masks the fender mounting gap, prevents leaves, branches and dirt from entering the engine hood hinge recess, reduces aerodynamic wind noise at higher speeds and ensures proper drainage of rainwater from the windshield into the drainage channels.

Fitment guarantee and VIN verification

Each cover undergoes a detailed check of the rubber profile's flexibility, inspection of the clips, and thorough cleaning before shipping.

Fitment / installation tip: The initial 4K8 designation (group 820) indicates that the part is designed exclusively for the Audi A7 Sportback body – it has a different fender edge and A-pillar base profile compared to the Audi A6 C8 (where part number 4K0 is used). The original OEM part fits perfectly along the windshield line and fender edge, eliminating the risk of the corner coming loose and wind whistling at highway speeds. Before purchase, we recommend comparing the OE number stamped on the underside of the part or verifying fitment using the vehicle's VIN.
