Power Window Regulator Rear Right for BMW E90 E91 - Easy Fit

In this review the focus is on a budget-conscious replacement: an OE-style power window regulator for the BMW E90/E91 rear right passenger side. The bottom line is that this unit is best for DIY owners who need a straightforward, cost-effective fix that lines up and installs without major modification. It replaces the factory regulator on 2007-on sedan and station wagon models and its primary appeal is a clean fit and functional restoration of window movement rather than bringing upgraded durability or included motorization.

Key Features

• OE replacement: Designed to match the original equipment geometry so the regulator aligns with existing mounting points and tracks for a straightforward swap.
• Easy fit: The part is intended for direct installation on rear right passenger doors, reducing installation time for a home mechanic or professional installer.
• Wide compatibility: Fits BMW E90 and E91 variants including 323i, 325i, 328i, 330i, 335i and M3 models from 2007 on, so buyers can be confident about model coverage.
• Body style specific: Labeled for sedan or station wagon body styles only, preventing confusion with coupe applications and ensuring correct fitment.
• Reference numbers provided: Reference numbers are supplied to help verify fitment against factory parts and service listings.

Who It's For

This regulator is aimed at BMW owners and independent mechanics who want a low-cost replacement that restores window functionality on rear right passenger doors. It is especially useful for those comfortable removing interior door panels and swapping parts without needing a replacement motor.

It is less suitable for buyers seeking a premium aftermarket upgrade, a regulator that includes a motor, or those who expect OEM-level longevity without compromise. If original manufacturer hardware quality is critical, consider sourcing factory parts or a higher-tier aftermarket option.
