What is a BMW OBD Scanner: A Professional Guide to BMW Diagnostic Tool

In the 1980s, figuring out what went wrong with your BMW was challenging. Eventually, the technical team came up with a brilliant idea that changed the game. BMW introduced OBD, or On-Board Diagnostics, an electronic tool that allows you to monitor your vehicle's performance and report technical issues like emission failure. This BMW diagnostic tool typically reads the codes sent by your BMW’s computer system and helps you recognize the problem. 

However, the system has been technically upgraded over the years with valuable features that ensure a safe BMW ride. In this blog, Global Diagnostics will tell you everything you should know about a BMW OBD scanner and its features.

How Does the BMW OBD Scanner Work?

As we mentioned, an OBD scanner for BMW cars helps you read the code to determine what is wrong with your vehicle. The Engine Control Unit keeps track of the sensors, engine, brakes, etc. To understand how this works, let’s break down the process step-by-step:

1.Plug the OBD port

You must connect the OBD scanner to the port under your BMW's dashboard. Once the scanner is attached to the port, it will automatically turn on. 

2.Send signal
Once you have plugged the scanner into your BMW, it will directly interact with the car, storing information on its conditions. On the other hand, the vehicle sends codes to the scanner that tell you the exact problem occurring within your car. 

3.Decoding the errors
The monitor screen will show you codes that will tell you precisely what is happening in your car. The OBD scanner will show you codes like:

• P1014: This means the parts of your BMW’s Valvetronic system are not working correctly, resulting in decreased emission or defect in the electrical connection.
  
• P0300: This code means your OBD scanner detected a cylinder misfire. This mainly means the fuel injector is clogged or the spark plug is malfunctioning.
• P112F: This code indicates problems in the vehicle's air mass system. Your BMW fault code reader tells you to pay attention to the Mass Air Flow sensor and air leaks in the car.
• P1176: This code informs you when the power switch experiences an extreme temperature rise, which can affect your vehicle's emissions. 

Like that, multiple such codes inform you about the technical difficulties in real time. 

Advanced BMW OBD Scanner

A regular OMB scanner will reveal the issues, but a BMW OBDII scanner is more than that. An OBDII will:

1. Read the codes
The scanner will instantly display the codes to help you identify the issue. 

2. Clear warning sign
The BMW OBDII will automatically reset the warning signs after you fix the issues.

3.Live Status

This BMW diagnostic software gives you real-time updates on fuel efficiency, engine temperature, etc.

4. Interact with the system.

The best part is that an OBDII scanner interacts with your BMW's significant features. For example, it can directly pair with battery replacement programs, airbags, anti-lock braking systems, transmission, etc.
