A-Premium Rear Right Power Window Regulator for BMW E90/E91 (2007+) — Passenger Side, No Motor

A-Premium's rear passenger-side window regulator replaces the factory unit and restores smooth, secure glass travel without a motor included.

This direct-fit OE replacement is engineered for BMW E90 and E91 sedans and wagons from 2007 onward, designed to snap into the original mounting points and reconnect to your existing motor and hardware. It addresses the common symptoms of a worn regulator—sluggish movement, uneven travel, or a window that won't stay in place—by offering a full mechanical assembly for the rear right (passenger-side) door. The part corresponds to reference numbers 51357140590 and 749-469 for straightforward identification.

How does this regulator improve a faulty rear passenger window?

Replacing the damaged regulator re-establishes correct alignment and friction levels so the glass moves evenly up and down. Because this unit matches OE dimensions and mounting points, installation keeps the door's original function and reduces stress on the existing motor and switch.

• Restores smooth glass travel and consistent sealing.
• Prevents binding and off-track movement that cause jams.
• Reduces wear on the window motor by re-aligning the mechanism.

Will it fit my BMW E90 or E91 and which models are compatible?

This regulator is built to fit BMW E90 and E91 body styles—specifically sedan and station wagon configurations—from model year 2007 onward. It covers multiple engine trims including 323i, 325i, 325xi, 328i, 328i xDrive, 330i, 330xi, 335i, 335xi, and M3 when the vehicle uses the rear right mechanical regulator matching the listed references.

• Fits rear right (passenger side) doors on E90/E91 sedans and wagons.
• Compatible with the listed BMW trims and model years 2007 and newer.
• Cross-references OE numbers 51357140590 and 749-469 for verification.

What tools and steps are needed for installation?

Installation requires basic hand tools and some familiarization with door panel removal; no electrical work is needed if you reuse the original motor and connector. Typical steps include removing the door trim, detaching the glass from the old regulator, unbolting the regulator assembly, and reversing the process with the new part.

• You'll need a screwdriver set, socket set, trim tools, and gloves.
• Keep the window supported while disconnecting and reconnecting the regulator.
• Test operation before reassembling the door panel to ensure correct fit.

Are there any limitations or things to check before buying?

This listing supplies the regulator assembly only; the motor is not included, so verify your current motor is functional or order a motor separately if needed. Also confirm your vehicle is the correct body style and side: rear right (passenger side) for sedan or station wagon models.

• Part does not include an electric motor—reuse or purchase separately.
• Designed exclusively for rear passenger-side doors, not front or left side.
• Double-check compatibility using the OE reference numbers provided.

Who is this for: This A-Premium rear right window regulator is intended for BMW E90 and E91 owners, DIY mechanics, and independent shops needing a reliable, direct-fit replacement for a broken rear passenger-side regulator. It's ideal if your window binds, falls out of alignment, or the regulator hardware has failed while the motor remains serviceable. Choosing an OE-style unit makes the repair quicker and helps maintain factory door function without modifying the vehicle.
