BMW 20-Pin to OBD2 16-Pin Female Adapter Cable, 30 cm

Older BMW vehicles carry the round 20-pin diagnostic connector under the hood; every current scan tool speaks 16-pin OBD2. This 30 cm adapter cable is the conversion: the 20-pin end seats in the engine-bay connector, and the OBD2 female end accepts the modern tool — the workshop’s existing equipment covers the older fleet without a second diagnostic box.

The construction is heavy-duty for years of service: the adapter body weighs around 127 g, finished in black, with the 30 cm lead keeping the tool within reach of the under-hood port rather than dangling across the bay. It converts BMW 20 Pin to the OBD2 16-pin interface on vehicles so equipped — with the honest note that a passive adapter passes what the vehicle carries; system coverage depends on the model’s protocol and the tool’s software support.

FAQ

Under-hood or under-dash?
The 20-pin round connector is the engine-bay port on the older models; the under-dash 16-pin era needs no adapter.

Will every tool function work?
The adapter passes the vehicle’s pins; coverage follows the model’s protocol and the tool’s BMW software support.
