Second Hand BMW i3 Window Regulator

The BMW i3 ran from 2013 to 2022 in a single generation, with a facelift arriving in 2017 that brought exterior and interior updates. The door structure and window regulator mounting points were not significantly redesigned at that facelift, but because this is a boundary worth caution, confirm with the breaker against your registration before purchasing. Always specify the side (NS or OS) and whether your car is the 3-door or 5-door variant.

These sit either side of the 2017 facelift, so while the i3 is a single-generation car and the body shell is broadly the same, the crossing of that facelift boundary is exactly the point to verify with the breaker against both registrations. Make sure you also confirm the door side — NS (nearside/passenger) or OS (offside/driver) — as regulators are not interchangeable between sides. A breaker who can check the part numbers against both years will give you the most reliable answer.

No, the trim level on the BMW i3 does not affect window regulator fitment — the door shell and regulator mechanism are the same regardless of whether the car is a base, Atelier, Lodge, or Suite grade. You may find trim-specific interior trim or door card differences when you come to refit, but these are cosmetic and the regulator itself is not trim-dependent. Just make sure you specify the correct side (NS or OS) and your model year when requesting a quote.

Yes — window regulators are side-specific and cannot be swapped between NS (nearside, passenger/left) and OS (offside, driver/right), so always confirm which side you need before ordering. In UK convention, NS is the passenger side and OS is the driver side, so double-check which door has failed before approaching a breaker. Ordering the wrong side is a common and easily avoided mistake.

The BMW i3 was sold in both 3-door and 5-door bodystyles, and the front door window regulators differ between the two because the doors themselves are different sizes and designs. If your car is the 5-door variant, make sure the breaker confirms the part came from a 5-door car; the same applies for 3-door examples. Always confirm this alongside the model year and door side (NS or OS) when getting a quote.

The BMW i3s shares the same body shell and door structure as the standard i3, so the window regulator fitment is driven by model year, body style, and door side rather than whether the car is the i3 or i3s. Trim and performance designation do not change the door frame or regulator mechanism. Confirm the year, 3-door or 5-door body, and NS or OS side with the breaker and you should be able to source from either variant without issue.
