How to Activate the 5 GHz WLAN Module Using an OBD Scanner for Volkswagen

Activating the 5 GHz WLAN module in your Volkswagen can significantly enhance your in-car connectivity experience. This guide will walk you through the process step-by-step, using an OBD scanner. As an experienced automotive technician specializing in Volkswagen vehicles, I'll share my expertise to ensure you can complete this task safely and effectively.

Understanding the 5 GHz WLAN Module

Before we dive into the activation process, it's important to understand what the 5 GHz WLAN module is and why it matters:

• The 5 GHz WLAN module allows for faster wireless connections in your vehicle.
• It enhances features like Android Auto and CarPlay, providing a smoother user experience.
• The 5 GHz band typically offers higher speeds and less interference compared to the 2.4 GHz band.

Required Tools and Preparation

To activate the 5 GHz WLAN module, you'll need the following:

• An OBD-II scanner with WLAN capability
• Access to your vehicle's OBD-II port
• Internet access for potential firmware updates
• A smartphone or tablet to run the necessary apps

Ensure your vehicle is parked in a safe location with the engine off before beginning this process.

Step-by-Step Activation Process

1. Connect the OBD Scanner

Locate your vehicle's OBD-II port, typically found under the dashboard on the driver's side. Insert the OBD-II scanner into this port.

2. Power On the Vehicle

Turn the ignition to the "ON" position without starting the engine. This will power up the OBD scanner.

3. Set Up the OBD Scanner

Follow these steps to set up your OBD scanner:

1. Download and install a compatible OBD app on your smartphone or tablet. I recommend using the Torque app, which is available in both free and pro versions.
2. Open the app and navigate to the settings menu.
3. Select "OBD2 Adapter Settings" and choose "Wi-Fi" as the connection type.
4. Connect your device to the OBD scanner's Wi-Fi network. The network name should be visible in your Wi-Fi settings, often starting with "OBDII" or a similar prefix.

4. Access WLAN Settings

Once connected, use the OBD scanner interface to navigate to the vehicle settings. Look for options related to Wi-Fi or WLAN settings.

5. Activate the 5 GHz Module

In the WLAN settings, you should find an option to enable or activate the 5 GHz functionality. Select this option and follow any on-screen prompts to complete the activation.

6. Verify Activation

After activation, it's crucial to verify that the 5 GHz module is working correctly:

• Check your vehicle's infotainment system for any new Wi-Fi options.
• Test the connection speed using a Wi-Fi analyzer app on your smartphone.
• Ensure that features like Android Auto and CarPlay are functioning smoothly.

Troubleshooting Common Issues

If you encounter any problems during the activation process, try these solutions:

Issue	Solution
Scanner not recognizing the vehicle	Check the compatibility of your OBD scanner with your specific Volkswagen model.
5 GHz activation fails	Ensure your vehicle's software is up to date. You may need to visit a Volkswagen dealer for the latest firmware.
Wi-Fi connection drops frequently	This could be due to interference. Try changing the Wi-Fi channel in your vehicle's settings if possible.
