Right Electric Tailgate Actuator / Tailgate Drive Spindle – 4K8827852L / 4K8827851L

Original electric actuator for raising and lowering the tailgate on the right side (spindle electric drive for the rear tailgate integrated with a tension spring and electric motor), 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 S and RS variants, based on the modular longitudinal MLBevo platform.

Original VAG group comfort system actuator. It consists of an electric motor with a screw/spindle transmission, an internal tension spring, a Hall sensor monitoring the angular position, and a wiring harness with sealed power and signal connectors. It is responsible for the fully automated, smooth, and quiet opening and closing of the large rear tailgate in the Sportback body style (via the button in the tailgate, the switch in the driver's door, the remote control, or a foot gesture with the Easy Open / virtual pedal package).

Fitment guarantee and VIN verification

Each electric actuator undergoes verification of motor smoothness, stroke fluidity testing, and inspection of the condition of the ball sockets and connector before shipping.

Fitment / installation note: The initial designation 4K8 (tailgate group 827) defines the force and stroke characteristics matched to the heavy Sportback tailgate in the Audi A7. Damage to the right actuator manifests as the tailgate tilting during movement, loud rattling from inside the cylinder, sticking halfway through opening, or a drive synchronization error in the tailgate control unit. After replacing the actuator, the basic settings procedure (adaptation of the tailgate's end positions) should be performed using a diagnostic tester or the closing button in the tailgate. Before purchase, we recommend comparing the OE number on the sticker on the part body or verifying it using the vehicle's VIN.
