VAS 5054A

The VAS 5054A is a professional wireless diagnostic interface, specifically designed for Volkswagen Group vehicles (VW, Audi, Seat, Skoda, Bentley, Lamborghini).

The VAS 5054A is the standard tool used in dealerships, offering superior diagnostic, coding, and programming capabilities compared to most multi-brand tools.


Its compact design integrates a high-performance Bluetooth module, transforming any laptop into a mobile and powerful industrial diagnostic tool.


The VAS 5054A is particularly valued for its ability to manage the complex communication protocols of modern ECUs, where generic interfaces fail.

Operational Advantages and Performance:

•    ODIS Integration (Online Diagnostic Information System): Unlike third-party tools, the VAS 5054A is natively recognized by the official VAG group software. This allows for fluid navigation through electrical diagrams, integrated repair manuals, and guided diagnostic procedures that assist the technician step-by-step.

•    UDS Protocol Management: Thanks to its advanced chip (Full Chip version), the interface communicates seamlessly with vehicles using the UDS (Unified Diagnostic Services) protocol, standard on models produced since 2010. This ensures ultra-fast data stream reading and stability during ECU flashing.

•    Mobility and Work Comfort: The integrated Bluetooth connection allows the technician to move around the vehicle, check components under the hood or at the rear while keeping the diagnostic screen in view, without the constraint of a USB cable dragging on the ground.

•    Robust Design: The housing is designed to withstand workshop environments (oil splashes, dust). The connectors are reinforced to withstand frequent plugging and unplugging on the OBDII port.


There are several variants on the market. Our VAS 5054A offered here includes:

1.    OKI M6636B Chip: Supports specific protocols for older models and UDS stability.

2.    TJA1054 Transceiver: For reliable communication on the CAN Low Speed bus.

3.    Quality Voltage Regulators: Protects the interface and the vehicle against voltage spikes.
