Understanding the Ross Tech Wiki 18057 Fault Code

The 18057 fault code, often encountered when using a Ross-Tech VCDS (Vag-Com Diagnostic System), typically indicates an issue with the vehicle’s immobilizer system, specifically a malfunction with the Access/Start Authorization.

Several factors can contribute to the 18057 error. These include:

• Faulty Key Fob: A damaged or deprogrammed key fob can disrupt communication with the immobilizer.

• Malfunctioning Immobilizer Control Unit: The immobilizer control unit itself could be faulty, requiring replacement or repair.
