Rear Driver Side Power Window Regulator with Motor - Direct Fit

In this review the Rear Driver Side Power Window Regulator with motor is evaluated for owners of BMW E90 and E91 models from 2006 to 2011 who need a reliable, direct replacement for a failed rear left window regulator. The bottom line: this assembly is a straightforward swap that restores smooth, quiet operation, and it stands out because it comes complete with the motor and is built to OE standards, making it the single best reason for owners seeking a practical repair rather than a costly dealer part.

Key Features

• Complete assembly: The unit includes the motor so customers replace the entire regulator and avoid diagnosing separate failures.
• OE fitment: Designed to match the original mounting points for E90 and E91 BMW 323i, 325i, 328i, 330i, 335i and related xDrive and xi models, so installation is straightforward.
• Multiple OE numbers supported: Compatible with OE references 748-468, 748468, 51357140589 and 67626927025, helping buyers confirm fit before purchase.
• Smooth operation: Built to OE standards so the window slides smoothly and quickly with minimal noise once installed.
• Rear left location: Specifically for the rear driver side position, reducing the chance of ordering the wrong side for sedan and wagon variants.

Who It's For

This part is best for BMW owners and independent mechanics who want a direct replacement for a failed rear driver side window regulator on 2006-2011 E90/E91 sedans and wagons, including 323i, 325i, 328i, 330i, 335i, 335d and M3 where listed. It suits people who prefer swapping a complete assembly with motor rather than troubleshooting separate components.

Those who should look elsewhere include owners of non listed model years or body styles and anyone who needs a right side or front regulator, as this unit is only for the rear left (driver side) location. Also, buyers seeking dealer-branded packaging or OEM-only purchase channels may prefer original factory sources.
