Interpreting BMW OBD codes requires the use of an OBD-II scanner or code reader. These devices can connect to the vehicle's OBD port and retrieve the stored codes. Each code consists of a series of alphanumeric characters, such as P0171 or B1200. The first character indicates the type of code, such as P for Powertrain or B for Body. The following characters provide more specific information about the issue, such as the system or component affected.

3. Common BMW OBD Codes and their meanings
BMW OBD codes can vary depending on the model and year of the vehicle, but there are some common codes that tend to appear across different models. Some examples include:

P0171: System Too Lean - This code indicates a problem with the engine's air-fuel mixture, usually caused by a vacuum leak or faulty oxygen sensor.

P0420: Catalyst System Efficiency Below Threshold - This code suggests an issue with the catalytic converter, often caused by a failing oxygen sensor or a malfunctioning converter.

P0300: Random/Multiple Cylinder Misfire Detected - This code indicates misfires in multiple cylinders, which could be caused by various factors like spark plug or ignition coil issues.
