Used BMW 6 Series Window Regulator

The E63 is the coupe and the E64 is the convertible, both produced from 2003 to 2010 with a facelift in 2007 — they share the same generation but the door frames and structures differ between body styles, so a regulator from the coupe will not cross over to the convertible. Always specify coupe or convertible when getting a quote, along with NS (passenger side) or OS (driver side) and whether your car is pre-facelift (2003–2007) or post-facelift (2007–2010). Confirm the exact part reference with the breaker against your registration to be sure.

The E63 coupe ran from 2003 to 2010, with a facelift introduced in 2007, and while the body generation is the same, door hardware sometimes changed at facelift points. Confirm with the breaker whether the specific regulator crosses that 2007 boundary, quoting your exact registration so they can check part numbers. Always specify NS or OS when asking.

Trim and engine variants like 630i, 645Ci, 650i, and M6 do not affect window regulator fitment on the E63 coupe — what matters is the generation (E63), the door side (NS or OS), and whether it is pre- or post-facelift. The M6 uses the same door structure as the rest of the E63 range, so there is no special M6 regulator. You may find cosmetic differences in interior trim around the door card, but the regulator mechanism itself is not trim-specific.

Yes — window regulators are side-specific, so a nearside (NS, passenger-side left) regulator will not fit the offside (OS, driver-side right) door and vice versa. Always confirm NS or OS clearly when requesting a quote from a breaker, as supplying the wrong side is one of the most common sourcing mistakes. Double-check against your registration to avoid unnecessary returns.

All production E63 and E64 models were fitted with electric window regulators as standard, so a manual unit is very unlikely to be relevant here. However, if you are unsure whether any mid-range changes affected the electric regulator mechanism across the production run, confirm this with the breaker against your registration rather than assuming all years are identical. Specifying your exact model year alongside NS or OS will help them identify the correct unit.

Both 2005 and 2009 fall within the E63/E64 generation (2003–2010), but 2005 is pre-facelift and 2009 is post-facelift, with the facelift arriving in 2007. Whether the regulator is a straight swap across that 2007 boundary is something you should confirm with the breaker against both registrations, as changes were sometimes made to door hardware at facelift. Make sure to specify the body style (coupe or convertible) and the side required (NS or OS) when you ask.
