Original Rear Hatch Glass (Heated Rear Window) – Series 4K8845051

Original factory rear hatch glass (safety tempered glass with an embedded heating grid and integrated radio/GPS antenna), 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 / 340 hp), 2.0 TFSI (40/45 TFSI), TDI diesel engines, and S7 and RS7 variants, based on the modular MLBevo longitudinal platform.

Original VAG group body glazing component. Made of high-quality, certified safety tempered glass (ESG) with integrated electrical defogging paths (rear window heating) and factory antenna fields that work with the antenna amplifiers in the hatch. It features a factory ceramic screen-printed frame (black masking strip) that protects the adhesive bond from UV radiation, and depending on the vehicle's factory configuration, it is available in a standard version (greenish/thermal insulation) or factory-tinted (Privacy Glass / equipment code 4KF).

Fitment guarantee and VIN verification

Every window undergoes a heating circuit continuity test with an electrical tester and a surface inspection for scratches before being listed for sale.

Fitment / installation tip: The beginning of the number 4K8 (glazing group 845) defines the window contoured for the sloping roofline of the Sportback body style in the Audi A7 (windows for the Audi A6 Limousine or Avant body styles have completely different dimensions and curvature). When selecting the window, the equipment code is key: 4KC (standard window, slightly greenish non-thermal) or 4KF (factory-tinted Privacy glass – dark glass tinted in the mass, not covered with film). Installing the original OEM window guarantees a perfect fit to the hatch frame without stress, proper radio antenna polarization, and immediate defogging operation. Before purchasing, we recommend reading the designation from the stamp in the corner of the window (Sekurit/Pilkington with the Audi logo) or verifying it using the vehicle's VIN.
