1. What is a VCDS Lite 1.2 Serial Number and Why Do I Need It?

The VCDS Lite 1.2 serial number is a unique identifier assigned to your software license. It’s necessary to activate the software from its default “Shareware” mode to a fully registered version. Without it, you’ll be limited in the functions you can perform, even though you can still access all the control modules in your car and perform a number of useful functions.

• Activation: The serial number is your key to unlocking the full functionality of VCDS-Lite.
• Full Functionality: Once activated, you’ll have access to advanced diagnostic and coding features.
• Updates & Support: Registration often grants access to software updates and technical support.

2. Where Can I Find My VCDS Lite 1.2 Serial Number?

The serial number is generated by the software itself on the computer where it’s installed. Here’s how to locate it:

• About Screen: Open VCDS-Lite and navigate to the “About” screen.

  • Serial Number Location: The serial number will be displayed on this screen.

• Copy and Paste: Highlight the serial number and use copy-paste to avoid errors when submitting it for activation.

• Untested Message: If you see a message indicating that VCDS-Lite is untested, you must first test the software as described in the FAQ before a serial number is generated.

3. What If I Don’t See a Serial Number?

If you don’t see a serial number on the “About” screen, it usually means VCDS-Lite hasn’t been properly tested on your system. Follow these steps:

• Test VCDS-Lite: Run a test to ensure the software communicates with your vehicle’s systems.

  • Go to the VCDS-Lite FAQ for instructions on how to do this.

• Communication: Ensure your interface is properly connected and configured.

• Recheck: After a successful test, revisit the “About” screen to see if the serial number has appeared.

4. How Do I Submit My VCDS Lite 1.2 Serial Number for Activation?

Once you’ve located your serial number, you need to submit it to register and activate VCDS-Lite.

• Registration Form: Visit the appropriate registration form on the Ross-Tech website.
• Paste Serial Number: Locate the “VCDS-Lite Serial Number” field and paste your serial number into it.
• Complete Form: Fill out the rest of the required information on the form and submit it.
• Important: Do NOT De-Activate any old versions of VAG-COM AFTER you have submitted an Activation request. That will change your current Serial Number and will totally foul up the Activation process.

5. What Should I Do After Submitting the Serial Number?

After submitting your serial number, keep an eye on your email for the activation file.

• Email Delivery: Ross-Tech will send you an email containing the activation file, usually within one business day. If you have not heard from us by the second business day after submitting your request, please follow up with an e-mail to [email protected] or give us a call.
• Verify Serial Number: Before saving the file, double-check that the serial number in the email matches the one displayed in VCDS-Lite.
• Save Activation File: Save the attached activation file to the correct directory on your computer.
  • Typically, this is C:Ross-TechVCDS-Lite.
  • Make sure the “Save as type:” field at the bottom shows “All Files (*.*)”

6. How Do I Verify That VCDS Lite 1.2 Is Activated?

After saving the activation file, you need to verify that VCDS-Lite is fully activated.

• About Screen: Return to the “About” screen in VCDS-Lite.

• License Status: Check the “License Status” field. It should now read “Fully Registered/Activated.”

• Unregistered/Shareware: If VCDS-Lite remains in “Unregistered/Shareware” mode, double-check that the file name of the activation file matches the first field of your serial number. If they don’t match, your serial number has changed and you will need to resubmit your request.

7. What If the Activation File Doesn’t Match My Serial Number?

If the activation file doesn’t match your serial number, it indicates a problem with the activation process.

• Resubmit: You’ll need to resubmit your serial number through the registration form.
• De-Activation: Ensure you haven’t de-activated any old versions of VAG-COM after submitting your activation request, as this can change your serial number.
• Contact Support: If problems persist, contact Ross-Tech support for assistance.

8. Can I Use VCDS Lite 1.2 with a Dongle Interface?

VCDS-Lite is designed for use with “dumb” interfaces, not dongle interfaces.

• Dongle Interfaces: If you have a KEY-, KII-, HEX-, or MICRO- series interface, you should use the current version of VCDS instead.
• Current VCDS: The current version of VCDS will read the license directly from your dongle interface.

9. Why Is Copy and Paste So Important?

Using copy and paste is crucial when dealing with serial numbers and activation codes.

• Typographical Errors: It eliminates the risk of typing errors, which can cause activation to fail.
• Efficiency: Copy and paste is faster and more accurate than manually typing long strings of characters.
