1. How Does VCDS Count VINs for Limited Licenses?
VCDS (VAG-COM Diagnostic System) counts VINs for limited licenses by storing them in the interface firmware. This means the number of vehicles you can diagnose is restricted by the hardware itself, specifically the VCDS interface cable. When you connect to a vehicle, VCDS checks if the VIN is already stored in the interface. If not, and you haven’t reached your limit, it stores the VIN.
The VIN (Vehicle Identification Number) limitation in VCDS is a contentious issue, especially among enthusiasts who work on multiple vehicles but are not engaged in commercial operations. This limitation, often set at three VINs for a standard license, can quickly become a hurdle for individuals who frequently diagnose and repair vehicles within their circle of friends, family, or personal collection. The frustration stems from the feeling that a legitimately purchased device is being artificially restricted to generate additional revenue. It’s important to understand the technical reasons behind this choice and its impact on users.
2. Why Store VINs in the Interface Firmware?
Storing VINs in the interface firmware is a deliberate design choice by Ross-Tech, the makers of VCDS, to combat software piracy and unauthorized use. By embedding the VIN count directly into the hardware, it becomes much harder for users to circumvent the licensing restrictions.
Here’s a more detailed explanation:
- Piracy Prevention: Software piracy is a significant concern for software developers. By linking the license to the hardware, Ross-Tech reduces the risk of unauthorized copies of VCDS being used on multiple vehicles without proper payment.

- Revenue Protection: Limiting the number of VINs encourages commercial users to purchase more comprehensive licenses, contributing to the revenue stream that supports ongoing development and support for VCDS.
3. What Are the Implications of This VIN Limitation?
The VIN limitation has several implications, both positive and negative:
- For Enthusiasts: As mentioned earlier, enthusiasts who work on multiple cars can find the VIN limit restrictive. They may need to purchase additional licenses or upgrade to a professional version of VCDS, which can be costly.
- For Commercial Users: Professional mechanics and workshops typically benefit from the system, as they would usually opt for a more comprehensive license that covers a higher number of VINs or offers unlimited usage.
- For Ross-Tech: The VIN limitation helps protect their revenue and ensures that they can continue to invest in the development and support of VCDS.
4. Can You Remove VINs from the VCDS Interface?
No, typically you cannot manually remove VINs from the VCDS interface yourself. Once a VIN is stored, it remains there until you either upgrade your license or the device is reset by Ross-Tech under specific circumstances.
There have been requests from users to allow VINs to be removed when a vehicle is sold or no longer owned. This feature could potentially alleviate the concerns of enthusiasts who legitimately cycle through vehicles. As of now, Ross-Tech does not offer a standard procedure for users to remove VINs themselves.
5. What Happens When You Reach the VIN Limit?
When you reach the VIN limit on your VCDS license, the software will prevent you from performing certain diagnostic functions on new vehicles. You will likely receive a message indicating that you have exceeded your VIN limit and need to upgrade your license.
At this point, you have a few options:
