NPAUTO's rear left (driver-side) power window regulator is an OE-fit replacement (motor not included) engineered for BMW E90 and E91 models from 2006 to 2012.

This replacement regulator restores smooth, quiet rear-window operation after the original assembly wears or fails. Built to match factory dimensions and mounting points, the unit fits rear left driver-side applications across multiple BMW E90/E91 trims, offering a direct-swap solution for technicians and DIYers who need a durable mechanical carrier without the motor component.

Which BMW models and years will this regulator fit?

This assembly fits a range of BMW E90 and E91 sedans and wagons produced between 2006 and 2012. It covers common engine and trim variations used across the model years to simplify parts selection.

• Compatible with 323i, 325i, 328i, 328xi, 330i, 330xi, 335d, 335i, 335xi and M3 E90/E91 variants
• Rear left (driver-side) placement—designed for the back door window
• Direct-fit replacement using OE-style mounting points and hardware

What does "without motor" mean and when would I choose this option?

"Without motor" indicates the regulator assembly does not include the electric motor or wiring; it provides the mechanical tracks, cables, and brackets only. Choose this when the original motor remains functional or when sourcing a separate motor to reuse or replace independently.

• Saves money when only the regulator mechanics are damaged
• Allows reuse of a working motor from the original assembly
• Compatible with aftermarket or OEM motors if needed later

How hard is installation and what should I expect during replacement?

Installation is typically straightforward for experienced DIYers or technicians because the part is manufactured to OE standards. The regulator mounts to the door inner panel using factory bolt locations and should align with the window track for smooth movement.

• Direct-replacement design—no door modifications required
• Standard automotive hand tools and basic panel removal skills needed
• Expect smooth, quiet movement when properly aligned and installed

What identifiers and warranty details come with the product?

The assembly is cross-referenced to original equipment numbers to help confirm correct fitment and part matching. NPAUTO supports the item with a limited warranty and customer service assistance if questions arise after purchase.

• OE reference numbers: 749-468 and 749-469 for verification

Who is this for: This regulator is aimed at BMW E90/E91 owners, independent mechanics, and restoration shops that need a dependable rear left window regulator without a motor—ideal when the motor is reusable or when you plan to source a motor separately. It suits customers who prefer a direct-fit, OE-style mechanical replacement to restore proper window movement and reduce noise in the door assembly.
