iCarsoft VAWS V4.0
Dealer-level diagnostics for Audi, Bentley, Bugatti, Lamborghini, SEAT, Skoda, Volkswagen, VW Commercial Vehicles, VW LT3 and MAN Light-Duty. Full bidirectional control, advanced ECU coding, 43 service functions, CAN-FD, AutoVIN and lifetime free Wi-Fi software updates.
VAWS V4.0 comes pre-installed for the V.A.G. group, including Audi, Bentley, Bugatti, Lamborghini, SEAT, Skoda, Volkswagen, VW Commercial Vehicles, VW LT3 and MAN Light-Duty. You can then download two additional supported vehicle make groups free of charge.
VAWS V4.0 can send commands directly to supported vehicle modules so technicians can test components without relying on the vehicle's normal switches. iCarsoft advertises 22+ active tests across onboard systems, with additional coverage added through updates.
VAWS V4.0 provides extensive ECU coding capability for major supported V.A.G. models, with iCarsoft highlighting coding support for many applications from approximately 2010 onward. A dedicated Coding menu provides direct access to supported coding functions.
Coding capability is highly vehicle- and module-dependent. Some personalization requires coordination with Basic Settings and Adaptation functions.
VAWS V4.0 includes lifetime free software upgrades delivered wirelessly over Wi-Fi. There are no annual update renewals for the included software.
CAN-FD support enables communication with supported newer Audi, Bentley, Bugatti, Lamborghini, SEAT, Skoda, Volkswagen, VW Commercial, VW LT3 and MAN Light-Duty applications using Flexible Data-rate CAN.
AutoVIN can automatically identify supported V.A.G. vehicles, reducing manual selection and VIN-entry errors. Manual vehicle selection remains available when AutoVIN is not supported.

iCarsoft advertises full-system V.A.G. group coverage from 1996 through 2025. The VAWS V4.0 uses the standard 16-pin OBD2 connection on supported applications.
Diagnostic coverage, ECU coding, active tests, adaptations and service functions vary by vehicle, model, production year, ECU and equipment configuration. Contact eAutoTools with the VIN when a particular function must be confirmed.
If you need a particular coding function, active test, reset, adaptation or calibration, contact eAutoTools with the vehicle VIN, model year and required procedure so coverage can be checked before purchase.
Give eAutoTools the Audi, VW or other V.A.G. vehicle model, year, VIN and function you need. We'll help you determine whether VAWS V4.0 is the right scanner for the job.
