• Operating System:
  • VCDS is designed to run on Windows operating systems.
  • It is compatible with Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows 11.
  • Both 32-bit and 64-bit versions of these operating systems are supported.
• Hardware:
  • Processor: A modern processor (CPU) with a clock speed of 1 GHz or higher is recommended for optimal performance.
  • Memory (RAM): At least 2 GB of RAM is recommended. More RAM may be beneficial when working with large datasets or running other applications simultaneously.
  • Hard Disk Space: A minimum of 100 MB of free disk space is required for installation. However, it is recommended to have more free space available for storing diagnostic data and software updates.
  • USB Port: A USB port is required to connect the VCDS interface to your computer. USB 2.0 or higher is recommended for faster data transfer.
• Software:
  • Drivers: The necessary drivers for the VCDS interface must be installed on your computer. These drivers are typically included with the VCDS software package or can be downloaded from the Ross-Tech website.
  • .NET Framework: VCDS may require the .NET Framework to be installed on your computer. If it is not already installed, the VCDS installer may prompt you to install it.
• Installation:
  • It is essential to install VCDS on your PC’s hard disk. Running it directly from other media is not recommended and may result in improper functioning.
  • It is crucial NOT to install VCDS in the Program Files tree on systems running Windows Vista or newer. This directory has restricted permissions, which can interfere with VCDS’s ability to access and modify files. The default installation folder is C:Ross-TechVCDS.
• Internet Access:
  • Internet access is not required to use VCDS for basic diagnostics and coding.
  • However, internet access is required to update the firmware in current-generation interfaces (HEX-NET and HEX-V2). It is recommended to update your interface firmware before using VCDS in a location without internet access.

By ensuring that your computer meets these system requirements, you can optimize the performance and reliability of VCDS for vehicle diagnostics and coding.

4. What Interfaces are Compatible with VCDS?

VCDS is compatible with licensed Ross-Tech interfaces, including HEX-, KEY-, KII-, or Micro-CAN series interfaces. It does not work with third-party interfaces or older “low-tech” interfaces.

Understanding the compatibility of VCDS with different interfaces is essential for ensuring proper communication between the software and your vehicle. Here’s a detailed overview of the compatible and incompatible interfaces:

Compatible Interfaces:

• HEX-NET: This is one of Ross-Tech’s most advanced interfaces, offering both USB and Wi-Fi connectivity. It supports a wide range of vehicles and diagnostic protocols.
• HEX-V2: This is a USB-based interface that offers similar functionality to the HEX-NET, but without Wi-Fi connectivity. It is a popular choice for professional technicians and enthusiasts.
• HEX+CAN: This is an older USB-based interface that supports both CAN and non-CAN vehicles. While it is still compatible with VCDS, it may not support some of the newer features and protocols.
• KEY-USB: This is a basic USB-based interface that supports non-CAN vehicles. It is a more affordable option for users who primarily work with older vehicles.
• KII-USB: Similar to the KEY-USB, this interface supports non-CAN vehicles and is a budget-friendly option.
• Micro-CAN: This is a compact USB-based interface specifically designed for diagnosing and coding newer Volkswagen, Audi, Seat, and Skoda vehicles that use the CAN bus.

Incompatible Interfaces:

• Third-Party Interfaces: VCDS is designed to work exclusively with Ross-Tech interfaces. It is not compatible with any third-party interfaces, clones, or knock-offs. Using a third-party interface with VCDS may result in damage to your vehicle’s electronic systems.
• Older “Low-Tech” Interfaces: Ross-Tech previously sold some older “low-tech” interfaces before 2004. These interfaces are no longer supported by VCDS.
• Discontinued Interfaces: Some older Ross-Tech interfaces, such as the HEX+CAN and Micro-CAN, may not work properly with 2019 or newer model cars.

Important Considerations:

• Model Year Compatibility: All model-year 2019 and newer cars require one of Ross-Tech’s current interfaces (HEX-NET or HEX-V2). Older interfaces may not be compatible with these vehicles due to changes in diagnostic protocols and security measures.
• SFD Protection: Support for some model-year 2020 and newer cars is limited due to Security Function Deployment (SFD). VCDS can unlock SFD-protected modules using “off-line” tokens generated by VAG’s servers, but Ross-Tech cannot supply these tokens.
• Interface Upgrade Program: If you are a registered user of the old VAG-COM or current VCDS-Lite software and need compatibility with newer cars, you should consider Ross-Tech’s interface upgrade program.

By using a compatible interface with VCDS, you can ensure reliable and accurate communication with your vehicle’s electronic systems.
