Experiencing issues with your car’s auto scan feature can be frustrating, especially when relying on tools like VCDS (VAG-COM Diagnostic System) for vehicle diagnostics. This article delves into a real-world user experience detailing problems encountered after a VCDS software update, focusing on the “Auto Scan Car” functionality and offering insights into potential troubleshooting steps.
The user reported encountering difficulties after updating their VCDS software from version 18.9 to newer versions, specifically 19.6.0.4 and 19.6.0.6. This issue manifested in the form of failed auto scans on their 2016 Audi Q7 (4M), a vehicle that previously scanned without problems on the older VCDS version. After the update, initiating an “auto scan car” resulted in the error message “Function not supported by the gateway.”
Further investigation revealed inconsistent behavior. While repeatedly clicking the “Gateway installation list” sometimes allowed it to work, attempting a full auto scan by pressing the “Start” button only yielded partial results, typically scanning just 4 or 5 modules out of the entire vehicle’s system. This incomplete scan made it impossible to get a comprehensive overview of the car’s diagnostic status.
The user also observed an anomaly in the scan process itself. In the older VCDS 18.9.x version, the auto scan process began with Module 01 (Engine). However, in the newer problematic versions, the scan inexplicably started with Module 17 (Instruments). This change in scan sequence further suggested an underlying software issue affecting the “auto scan car” functionality.
To illustrate the problem, the user provided a diagnostic log from VCDS version 19.6.0.4. This log clearly shows an incomplete scan, listing only four modules: Media Player 1, Sound System, TV Tuner, and Information Electr. Notably, the Information Electr. module is flagged with a “Malfunction” status, and the log includes fault codes related to “Function Restricted due to Missing Message(s)”. These codes, U1111 00, point towards communication issues within the vehicle’s network, possibly contributing to the failed “auto scan car”.
