- Read and Clear Diagnostic Trouble Codes (DTCs): These codes are generated by the car’s computer when it detects a problem.
- Monitor Real-Time Sensor Data: This data can help you pinpoint the source of a problem.
- Perform Live Data Logging: This data can be used to diagnose more complex problems.

Here are some tips to help you locate the OBD port on your BMW E46:
- Check the Owner’s Manual: The owner’s manual for your E46 should show you where the OBD port is located.
