BMW has a System Where you can Scan Codes to get Information about the Car
This system is known as the On-Board Diagnostics, or OBD, system. The OBD system is used to diagnose problems with the car. The service light and oil light can both be reset with it. To scan codes on a BMW, you will need a unique tool called an OBD scanner. You can purchase an OBD scanner online or at a local auto parts store. Once you have an OBD scanner, follow these steps:
- Plug the OBD scanner into the diagnostic connection under your BMW dashboard.
- Switch on the ignition but do not run the engine.
- Follow the instructions that come with your OBD scanner to run a scan.
- Once the scan is complete, write down any codes that are displayed.
- If you see a code that says “P0171,” there is a problem with your fuel system. To resolve this, take your vehicle to a professional and have the fuel injectors checked.
These are examples of code you may see when you scan your BMW. If you see any other codes, consult your owner’s manual or an online BMW forum for more information. Scanning codes on a BMW can be helpful if you are having problems with your car.
Furthermore, it is critical to realize that these codes are only a beginning point for identifying the issue. If you are not accustomed to working on your automobile or do not have the necessary tools, take it to a mechanic and have them determine what’s wrong.

There are Three Types of Codes – Functional, Control, and Diagnostic
Applicable codes are used to request information about a specific function or system of the car. For example, you might use a functional code to determine if the doors are locked.
Control codes activate or deactivate a specific function or system of the car. For example, you might use a control code to turn on the headlights.
Diagnostic codes are used to diagnose problems with the car. For example, you might use a diagnostic code to determine why the check engine light is on.
When you scan codes on your BMW, you will likely see a mix of these three codes. However, most of the time, you will be dealing with diagnostic codes. These codes can help you figure out what is wrong with your car.
If you see a Code that you do not Recognize
There are a few ways to look up the meaning of an unfamiliar code. One way is to consult your owner’s manual. Another way is to use an online BMW forum. Or, you can take your car to a mechanic and have them decode the code for you.
Keep in mind that codes are just a starting point for diagnosing problems with your car. They are not always accurate and do not always tell you everything you need to know about the problem.
Sometimes, you may need multiple codes to determine what is wrong with your car. For example, if you see a code for a misfire in cylinder 4, you might also need to use a code for the ignition coil in that cylinder.
When you are done scanning codes on your BMW, be sure to disconnect the OBD scanner from the diagnostic port. And, if you do not plan on using it again soon, be sure to store it in a safe place.
You can also use Code scans to Update your car’s Software and keep it Running Smoothly
Like your computer or phone, your car’s software can become outdated. It can cause problems with the way your car runs. To fix this, you can use an OBD scanner to update the software on your BMW. Updating your car’s software is a simple process:
- You will need to download the latest software for your BMW from the internet.
- Connect your OBD scanner to the diagnostic port under the dashboard of your BMW.
- Follow the instructions with your OBD scanner to update the software on your car.
It is vital to keep your car’s software up-to-date. By doing this, you can avoid potential problems and keep your car running smoothly.
