The long-term solution is . If you work on VAG cars more than once a month, it pays for itself in diagnostics alone. On some 64-bit laptops, the loader may fail
Improperly installed USB drivers are a primary cause of interface detection issues. For a clone to work, the specific drivers provided with the loader must be used, rather than the default Windows or Ross-Tech drivers. If you work on VAG cars more than
