The HEX-NET VCDS interface allows for advanced diagnostics and modifications on VAG vehicles (Volkswagen, Audi, Seat, and Skoda). One common function is releasing the electronic parking brake using VCDS. This guide explains how the HEX-NET facilitates this process and what you need to know.
Understanding the HEX-NET and VCDS
The HEX-NET is a powerful diagnostic interface that connects to your Windows PC via USB or Wi-Fi. This allows your computer to communicate with your vehicle’s onboard computer systems using the VCDS software. This software provides access to various modules, including the electronic parking brake system. The interface acts as a “dongle,” meaning the activation for the full version of VCDS is built-in, simplifying setup and use.
Why Release the Parking Brake with VCDS?
There are several reasons why you might need to release the parking brake electronically using VCDS:
- Brake Pad Replacement: Releasing the parking brake electronically is often necessary to retract the caliper pistons for brake pad replacement on vehicles with electronic parking brakes.
- Troubleshooting: VCDS allows you to diagnose and pinpoint issues within the parking brake system. Releasing the brake through the software can help isolate problems.
- Maintenance: Certain maintenance procedures, such as caliper lubrication or parking brake adjustments, may require the electronic release of the parking brake for proper access.
How to Release the Parking Brake with HEX-NET VCDS
While the specific steps can vary slightly depending on the vehicle model and year, the general process is as follows:
-
Connect the HEX-NET: Connect the HEX-NET interface to your vehicle’s OBD-II port and to your Windows PC via USB or establish a Wi-Fi connection.
-
Launch VCDS: Open the VCDS software on your computer.
-
Select Control Module: Navigate to the “Select Control Module” option.
-
Choose Parking Brake Module: Identify and select the module responsible for the parking brake system. This is typically labeled as “Parking Brake” or a similar designation.

Important Considerations
- Safety First: Always ensure the vehicle is on a level surface and chocked before releasing the parking brake electronically.
- Consult Your Vehicle’s Repair Manual: Refer to your specific vehicle’s repair manual for detailed instructions and safety precautions. The process can vary between models.
- Proper Equipment: Ensure you are using a genuine Ross-Tech HEX-NET interface and licensed VCDS software to avoid compatibility issues and ensure proper functionality.
Conclusion
The HEX-NET VCDS interface provides a comprehensive solution for diagnosing and interacting with VAG vehicle systems, including the electronic parking brake. Releasing the parking brake electronically using VCDS can simplify maintenance and troubleshooting tasks. However, it’s crucial to prioritize safety and consult your vehicle’s specific repair manual for detailed instructions. Using the HEX-NET and VCDS correctly will empower you to perform essential maintenance and repairs effectively.
