Learning to use the tool is no rocket science! It automatically turns on as soon as you plug the OBD2 -16PIN extension cable into the gadget & into the vehicle’s connecting port.

Besides, the user manual is detailed enough for an average Joe to read Diagnostic Trouble Codes (DTCs), clear warnings, reset oil, airbag and the likes with it.

The ease of firmware update, free upgrades and data transfer via storage disks is another plus for this awesome auto-tech-gadget from Xtool.

We can’t fault the device in any way as it lets you get started with basic troubleshooting for Volkswagen, Audi, Skoda, SEAT and other supported vehicle brands. This is like getting what’s obtainable only in major dealership service centers for cheap.

We can recommend Xtool VAG401 OBD2 auto-diagnostic tool to owners of  SEAT, Audi, Volkswagen, and Skoda car models.
