A-Premium Power Window Regulator Rear Passenger Side for BMW E90/E91 (2007+) — Without Motor, Direct-Fit OE Replacement

The A-Premium Power Window Regulator Rear Passenger Side without motor is an OE-replacement mechanism designed to restore smooth, reliable rear-right window operation for compatible BMW E90/E91 sedans and wagons.

If the rear passenger-side window in your BMW 323i, 325i, 328i, 330i, 335i or M3 (2007 and later E90/E91 models) is sticking, falling, or won’t hold position, this A-Premium regulator provides a direct-fit alternative to the factory part. It replaces the mechanical lifting assembly (does not include the motor) and matches the original mounting points and cable routing so installation is straightforward with basic tools.

How does this regulator fix a window that slides or won’t stay up?

The regulator replaces worn or broken cable, guides, and pivot points that cause the glass to drop or move unevenly. By restoring proper tension and alignment, the window travels smoothly along its track and locks in place when raised. Because it’s a direct-fit OE-style unit, you won’t need to modify the door panel or frame.

• Restores cable-driven lift mechanism and guide rails
• Prevents glass from slipping or rattling in the door
• Mounting holes and brackets match original factory locations

Will this part fit my BMW E90 or E91 and how do I check compatibility?

This A-Premium regulator is compatible with a wide range of BMW E90/E91 models from 2007 onward, including 323i, 325i, 325xi, 328i, 328i xDrive, 330i, 330xi, 335i, 335xi and M3, for sedan and station wagon body styles. Verify fit by comparing the reference numbers (51357140590, 749-469) to your OEM part or by checking vehicle year, model, and door location. If your car uses a separate motor assembly, confirm you already have or will transfer the existing motor to this regulator.

• Fits rear right / passenger-side door on sedan or station wagon
• Reference numbers: 51357140590 and 749-469 for cross-checking
• Designed for 2007+ BMW E90/E91 model lines listed above

What’s included and what tools or parts do I need for installation?

The package contains the window regulator assembly without the electric motor—intended as an OE replacement unit. You’ll typically reuse the vehicle’s original motor, mounting hardware, and trim clips unless they’re damaged. Installation requires basic hand tools and moderate mechanical experience; door panel removal and careful cable routing are part of the process.

• Included: OE-style regulator assembly (no motor)
• Often reused: original window motor, bolts, and electrical connector
• Tools: screwdriver, socket set, trim tools, and torque wrench recommended

How durable and reliable is this A-Premium regulator compared with OEM?

The A-Premium regulator is manufactured as an OE replacement to meet factory fit and function, using comparable materials for cable, brackets, and guides. Proper installation and use with a functioning motor will provide long service life similar to the original regulator. Routine inspection and lubrication of sliding parts can extend performance and reduce noise over time.

• Engineered to match OEM mounting and operation
• Quality materials for cables, rollers, and brackets
• Recommended: inspect motor and fasteners during replacement

Who is this for: This A-Premium rear passenger-side window regulator is aimed at DIY mechanics, independent repair shops, and BMW owners who need an exact-fit replacement for a failing rear-right window mechanism on E90/E91 sedans or wagons. It’s ideal if you already have a working motor to reuse or plan to transfer the original motor during installation and want a cost-effective, OE-compatible repair solution.
