Original BMW Front Convertible Top Lock Drive Motor for BMW 3 Series, M3, 6 Series, and M6 Convertible (1994–2010)

BMW's front locking mechanism drive, part number 67-61-8-370-816, is the Original BMW electric motor that operates the convertible top's locking mechanism on E36, E46, and E64 BMW convertibles. It is the part sold here as a convertible top motor. A locking mechanism drive moves the latches that secure the top, so the locking step is handled electrically. This drive weighs 600 g (1.3 lb) and is made in the Czech Republic. BMW has built it since March 1996, and the one part spans three generations of BMW open cars, from the E36 3 Series Cabrio through the E46 Convertible to the E64 6 Series Convertible.

Original BMW Parts carry a 24-month parts warranty.

BMW identifies this part as the front locking mechanism drive, a narrower description than the general term convertible top motor. Its position code places it at the front of the top system, and its name ties it to the locking mechanism specifically. Within the E64 range, BMW applies the same drive to both the early 6 Series Convertible and the later facelift version, so a mid-cycle change on that car does not call for a different number.
