Cheap BMW M3 Window Regulator

No — the E36 M3 ran from 1992 to 1999 and the E46 M3 from 2000 to 2006, and these are entirely different generations with different door structures, so the regulators are not interchangeable. Always make sure you also match the side (NS for passenger/left, OS for driver/right) when sourcing from a breaker.

The E46 M3 covers 2000 to 2006 as a single generation, so regulators from within that range are generally considered the same application — but always confirm the side (NS/OS) matches. Check with the breaker against your registration to be sure, as minor production changes can occur within a generation.

No — the E46 M3 (2000–2006) and the E90/E92/E93 M3 (2007–2013) are separate generations with completely different door frames and regulator assemblies, so parts from one will not fit the other. Make sure you source a regulator that matches both the correct generation and the correct side (NS or OS).

Trim level itself does not affect window regulator fitment — what matters is the generation, the body style, and the door side (NS/OS). However, bear in mind that a regulator from a standard E90 saloon donor may look or feel slightly different cosmetically, but the fitment frame is what counts. Confirm against your registration with the breaker to be safe.

Yes, absolutely — window regulators are side-specific, so you must specify NS (nearside, passenger/left) or OS (offside, driver/right) when getting a quote from a breaker. The E92 M3 is a coupe, so there is no rear door to worry about, but getting the front side wrong means the part will not fit. Always quote your registration to the breaker so they can pull the correct side.

These are different generations — the E90/E92/E93 M3 ran from 2007 to 2013 and the F80 M3 from 2014 to 2018 — and regulators are not expected to cross that generational boundary. Confirm with the breaker against your registration, as door structures differ significantly between these two platforms.
