For BMW enthusiasts and owners, maintaining peak performance and understanding your vehicle’s health is paramount. The BMW Scanner 1.4.0 car diagnostic tool offers an accessible and cost-effective way to delve into your BMW’s systems, right from your own garage. Forget expensive dealership visits for simple diagnostics or feature customizations. This tool empowers you to read and clear error codes, and even unlock hidden features within your car.
What is the BMW Scanner 1.4.0 and Why Do You Need It?
The BMW Scanner 1.4.0 is a specialized car diagnostic tool designed specifically for BMW vehicles. Unlike generic OBD-II scanners that offer limited insight, this tool provides deeper access to your BMW’s electronic control units (ECUs). Think of it as a key to understanding your car’s complex language.
Why is this beneficial? Modern BMWs are sophisticated machines with numerous sensors and computer systems monitoring everything from engine performance to comfort features. When a problem arises, or even a minor glitch occurs, your BMW’s computer stores error codes. The BMW Scanner 1.4.0 allows you to read these specific error codes, translating them into understandable descriptions, far beyond the generic codes a standard OBD-II scanner might provide. This precision helps you pinpoint issues accurately, saving time and potentially costly misdiagnoses.
Beyond diagnostics, this tool also offers coding capabilities. BMWs are often pre-programmed with features that are region-specific or optional extras. The BMW Scanner 1.4.0 can unlock some of these hidden features, allowing you to personalize your car to your preferences.
Key Features of the BMW Scanner 1.4.0
This versatile tool boasts a range of functionalities that make it an invaluable asset for any BMW owner:
- Comprehensive Diagnostics: Read and clear fault codes across various BMW systems including engine, transmission, ABS, airbags, and more. The scanner provides detailed descriptions of errors, not just generic code numbers, making troubleshooting much more intuitive.
- Feature Coding and Customization: Unlock and modify various vehicle settings. Examples include:
- Remote Window and Sunroof Control: Enable one-touch closing of windows and sunroof using your key fob – a feature that may be disabled in some regions.
- Lighting Adjustments: Disable or enable daytime running lights, activate flashing lights upon locking/unlocking, and even configure your car for aftermarket HID headlights to prevent error messages.
- Convenience Features: Disable automatic door locking at speed, customize onboard computer (OBC) checks, and more.

Getting Started: What You’ll Need
Before you begin your DIY diagnostic and coding journey, gather these essential items:
- BMW Scanner 1.4.0 with Software: This is the core component. Ensure it comes with the software CD.
- Laptop Running Windows XP (or Virtual Machine): The software is designed for older Windows operating systems. A virtual machine like VMware or VirtualBox on a modern laptop running Windows 10 or 11 can effectively emulate a Windows XP environment.
- Small Phillips Head Screwdriver: Needed if soldering is required to enable coding features (some scanners come pre-soldered).
- Soldering Iron and Solder: Only necessary if your scanner doesn’t come pre-soldered for coding functionality.
Step-by-Step Guide: Unleashing the Full Potential
Follow these steps to effectively use your BMW Scanner 1.4.0:
Soldering for Coding (Check First!)
Important: Before proceeding with soldering, test your scanner to see if coding functions are already active. Some units are shipped pre-soldered. If coding works out of the box, you can skip this soldering step entirely!
If coding is not immediately available, you will need to perform a simple soldering modification to enable these features.
- Open the Scanner Housing: Carefully remove the four small screws on the back of the BMW Scanner 1.4.0 using your Phillips head screwdriver. Gently separate the two halves of the housing to reveal the circuit board.
- Locate Pins 7 and 8: Orient the circuit board so the red and green LEDs are facing downwards. Identify pins 7 and 8. Visual aids are helpful – refer to online images or diagrams if needed (like the one from the original article).
- Solder Pins 7 and 8 Together: Using your soldering iron and solder, carefully bridge pins 7 and 8 with a small amount of solder. If you are new to soldering, practice on scrap materials first. The connection needs to be solid but avoid excess solder.
- Reassemble the Scanner: Once the solder cools, carefully reassemble the scanner housing and tighten the screws.

Software Installation and Setup
- Install Software: Insert the software CD that came with your BMW Scanner 1.4.0 into your Windows XP laptop or virtual machine. Run the installer and follow the on-screen instructions. It is recommended to install the software to your desktop for easy access.
- Connect the Scanner: Plug the BMW Scanner 1.4.0 into your laptop using the provided USB cable.
- Driver Installation: Windows will detect new hardware but likely won’t find drivers automatically. Navigate to your C drive, then to the “BMW Scanner” folder created during installation. Inside, find the “drivers” folder. Follow the PDF instruction within this folder to manually install the necessary drivers. This step is crucial for your computer to communicate with the scanner.
Running Diagnostics and Clearing Error Codes
- Connect to Your BMW: Locate the OBD-II port in your BMW, usually found under the driver’s side dashboard. Open the port cover and firmly plug in the BMW Scanner 1.4.0.
- Turn Ignition to Position 1: Insert your BMW key into the ignition and turn it to position 1 (accessory position). This powers on the car’s electronics without starting the engine.
- Launch the Software: Open the BMW Scanner 1.4.0 software on your laptop.
- Initiate Scan: Click “Continue” in the software interface. It might prompt you to turn the key – since you’ve already done this, simply click “Continue” again. The software will identify your BMW model and list its factory options.
- Start Diagnostic Scan: On the main screen, click the “Scan” button. The software will communicate with various modules in your BMW, scanning for error codes. Note that the scanner might not connect to every single module listed, which is normal for this tool and sufficient for most DIY needs.
- Review and Clear Errors: Once the scan is complete, the software will display any stored error codes. Double-click on a line with errors to see detailed descriptions. If an error is no longer relevant (e.g., a temporary glitch that has resolved), you can select it and click the “Clear Errors” function.

Coding Vehicle Features
- Access Coding Modules: In the main software window, double-click on the module you want to code (e.g., “ZKE” for central body electronics, which controls windows, locks, etc.).
- Navigate to Coding Section: In the module-specific window, look for a “Coding” button, then “Recoding.”
- Explore Coding Options: A new window will appear with a list of customizable features. These options vary depending on the module and your BMW model. Examples include window control, auto-locking, lighting features, and more.
- Make Your Selections: Carefully review each option and select or deselect features as desired.
- Write Changes: Once you’ve made your coding selections, click the “WRITE” button (usually in the lower right corner) to apply the changes to your BMW.
- Exercise Caution: Important: Only modify settings you understand. Incorrect coding can lead to unexpected behavior or issues. If you are unsure about a setting, research it online or leave it untouched.
