BOXI Front Left Window Regulator For BMW F30/F31 320i-340i, M3 (2012-2018) - Without Motor

Is your BMW's window making a horrible noise or not moving at all?

This is the fix.

It's a front left (driver side) window regulator from BOXI for the BMW F30 and F31 chassis.

It fits a ton of models from 2012 to 2018, including the 320i, 328i, 335i, 340i, and even the M3.

Just be aware, this is the regulator mechanism only – it does NOT include the window motor, so you'll need to reuse your existing motor or buy one separately.

It's a direct replacement for OEM part numbers like 51337281885.

Brand new, 1-year warranty.
