A rear right window lift mechanism listed under Audi part number 8V4839462 for A3 S3 and RS3 8V models. The regulator carries the door glass on a guided rail and cable drive, so a frayed cable or cracked carrier is what leaves a window grinding, stuck halfway or dropped inside the door. Coverage includes A3 8V FWD and S3 8V Quattro 2.0T from 2015 to 2020 plus RS3 8V 2.5T from 2017 onward. Mounting points and cable routing follow the factory unit, so the job stays a normal door card and moisture barrier removal. Confirm the OE number and rear right position before ordering. One window lift mechanism is included.
OE Number 8V4839462 Match: Built to Audi part 8V4 839 462 for the rear right door, so mounting points, rail length, and cable routing follow the original regulator
Covers A3 S3 and RS3 8V: Fits A3 8V FWD and S3 8V Quattro 2.0T from 2015 to 2020, along with RS3 8V 2.5T models built from 2017 onward
Fixes Stuck or Dropped Glass: Replacing a frayed cable and worn carrier restores smooth rear window travel, and stops the glass from falling back into the door shell
Rear Passenger Door Repair: Aimed at the rear right door where a failing regulator brings grinding noise, slow travel, and glass that never seals against the frame
Guided Rail and Cable Drive: The steel rail and cable assembly keeps the glass square in the channel, so travel stays quiet and even every time the switch is pressed
Specification: OEM Part Number: 8V4839462 / 8V4 839 462; Placement: Rear Right; Quantity: 1 Pc
