Here’s why: 1. New Trucks Are Incompatible with Old Software If you service a 2024 Volvo or DAF, the older software will either fail to connect or show garbled data. You will waste hours trying to diagnose a problem that doesn’t exist. 2. Security Vulnerabilities The old USB driver had a buffer overflow exploit (CVE-2023-2842). While unlikely to be targeted in a repair shop, the updated version closes this hole. 3. Telematics Compliance Some fleet customers now require diagnostic tools to log data in a standardized format. The Woron Scan 109 software updated version exports fault logs in CSV and PDF formats compliant with FMCSA and TÜV standards. 4. Windows 11 22H2+ Compatibility Microsoft’s latest updates have broken many legacy drivers. If you recently updated your laptop, the old Woron software may simply crash on launch. The new version is fully certified for Windows 11.
