BMW 20 Pin OBD1 - 16 pin OBD2 Adapter

What is the BMW 20 pin adapter for?

This BMW 20 pin adapter is specifically for connecting your error code reader with 16 pin connector to your BMW with OBD1 20 pin connector. The round 20 pin connector can be found in BMWs produced up to the year 2001. Some BMWs are equipped with 2 diagnostic connectors; the round 20 pin connector under the hood and the OBD 16 pin connector near the dashboard. When 2 connectors are present, you should use the round 20 pin connector under the hood, because through this connector most modules can be read. The 20 pin socket under the hood is often found very close to the engine block. The connector is very easy to reach and is sealed around a cap.

Why buy a BMW 20 pin adapter cable?

If you own an older BMW, pre-2001, your BMW has a round 20-pin diagnostic port. To read your BMW, you will need this adapter cable and a suitable diagnostic tool that can handle older OBD1 connections. Through the 20-pin connection under the hood, with the appropriate readout tool, you can read out most systems in your BMW. Via the 16-pin connection near your dashboard, some functions may not work, as they are not yet fully supported.
