1. Understanding VCDS Auto Scan
VCDS (VAG-COM Diagnostic System) Auto Scan is a feature within the VCDS software that scans all the control modules in a vehicle to retrieve comprehensive information. This includes part numbers, component numbers, software coding, Work Shop Codes (WSC), and any stored fault codes. It’s an indispensable tool for diagnosing issues in Volkswagen, Audi, Seat, and Škoda vehicles. According to Ross-Tech, the developers of VCDS, this function provides a quick overview of the vehicle’s health.
1.1 Key Benefits of Using VCDS Auto Scan
- Comprehensive Diagnostics: Scans all modules to identify issues.
- Detailed Information: Provides part numbers, coding details, and fault codes.
- Time-Saving: Quickly assesses the vehicle’s overall status.
1.2 How VCDS Auto Scan Works
The Auto Scan function communicates with each electronic control unit (ECU) in the vehicle. It requests and retrieves data such as the module’s identification, software version, and any diagnostic trouble codes (DTCs) that are stored. This data is then compiled into a report, providing a snapshot of the vehicle’s electronic health.

3. Step-by-Step Guide to Performing a VCDS Auto Scan
Follow these steps to perform a VCDS Auto Scan effectively.
3.1 Selecting the Correct Chassis Type
The first step in performing an Auto Scan is to select the correct chassis type. This ensures that VCDS scans only the modules that are plausible for the vehicle.
- Identify Chassis Type: The chassis type is typically the 7th and 8th digits of the VIN number. For example, WAUZZZ4F36N111022 has 7th and 8th digits of 4F and is a “4F, Audi A6 C6”.
- Use the Search Box: Use the search box to narrow down the choices. For example, typing “Touareg” will filter the list to show relevant chassis types.
- Refer to Vehicle Application Charts: For additional help, refer to Ross-Tech’s Vehicle Application Charts.
3.2 Using Auto Detect (CAN Only)
For newer cars with a fully CAN-based diagnostic system, VCDS can automatically determine which modules are installed.
- Select Auto Detect (CAN Only): Choose this option as the Chassis Type.
- Initiate Scan: VCDS will automatically identify and scan the modules present in the vehicle, making the process faster.
3.3 Customizing the Auto Scan with MyAutoScan.TXT
VCDS allows you to create a custom profile for your vehicle by editing the MyAutoScan.TXT file.
- Access MyAutoScan.TXT: Click on the hyperlink above the Chassis Type selection to open the file in your default text editor (like Notepad).
- Create Custom Profile: Edit the file to include specific modules or settings relevant to your vehicle.
- Save Changes: Save the changes to the file. VCDS will use this custom profile during the Auto Scan.
3.4 Understanding UDS Aggressive Mode
The UDS Aggressive Mode is enabled by default and retrieves all fault codes, including those not shown by the factory scan tool.
- Leave Enabled for Comprehensive Scan: Keep the box checked to ensure all fault codes are retrieved.
- Disable for Factory Scan Correlation: Uncheck the box to correlate results with what would be seen by the factory scan tool in “Self Diagnostics” mode.
3.5 Displaying Freeze Frame Data
The Display Freeze Frame Data checkbox adds freeze frame data for fault codes on control modules using the KWP-2000 protocols.
- Enable for Additional Data: Check the box to include freeze frame data in the scan results.
- Disable for Cleaner Results: Uncheck the box to make the results less cluttered, especially in scans with many fault codes.
3.6 Starting the Auto Scan
