Choosing the Right BMW E36 OBD2 Adapter

If your E36 has a 20-pin port, you’ll need a 20-pin to OBD2 adapter. These adapters allow you to connect a standard OBD2 scanner to your car’s diagnostic system. It’s essential to choose a high-quality adapter to ensure reliable communication and accurate data. Cheaply made adapters can sometimes cause connectivity issues or even damage your car’s electronics. If you are unsure about your vehicle’s system, understanding how to tell if your vehicle is obd1 or obd2 can be invaluable.

Later E36 models already have the standard OBD2 16-pin port, meaning you won’t need an adapter. You can directly connect any OBD2 scanner to the port located under the dashboard, typically near the steering column.
