It does not perform scanning itself; instead it connects your existing OBD2 tool to the car’s 20-pin port so you can read codes, run system checks, and perform coding functions supported by your scanner and vehicle. The cable is built with heavy-duty materials and precision molding to endure repeated use while maintaining stable signal transmission.\u003c\/p\u003e\n\n\u003ch3\u003eWhich BMW models will this adapter work with?\u003c\/h3\u003e\n\u003cp\u003eThe Autel 20-pin to 16-pin cable supports a wide range of BMWs that originally shipped with a 20-pin diagnostic connector. It’s compatible with many E-series and early R-series platforms commonly found in older BMW fleets. Always verify your vehicle’s port type before ordering.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible models include: E28, E30, E32, E34, E36, E38, E39, E46\u003c\/li\u003e\n  \u003cli\u003eAlso fits select models: E52, E53, R50, R52, R53\u003c\/li\u003e\n  \u003cli\u003eNot a scanner — meant only to adapt the physical connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and use the adapter with my OBD2 scanner?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward and requires no drivers. Plug the male 20-pin end into your BMW’s factory port, then attach your OBD2 scanner’s 16-pin plug to the female end.
