KINGBOLEN SOLOSCAN VW Audi Skoda Bidirectional Scan Tool

A VAG-group only diagnostic dongle for VW, Audi, Skoda, Seat and, per the listing, Bentley, Bugatti and Lamborghini. It plugs into the OBD2 port and runs through the Ediag app -- there is no screen on the device, the phone is the display -- over a Bluetooth connection with no cable to the port. It covers 99% of VAG platform vehicles.

Full-system diagnosis reaches past the engine controller into the automatic transmission, ABS, SRS, chassis and battery electronics, reading and clearing codes, live data streams and freeze-frame data on each module. That matters on a DSG or Tiptronic box throwing an intermittent code: you can watch transmission-side live data during a test drive instead of relying on a generic P-code alone.

Bidirectional active testing drives electronic switches, fuel system circuits, cooling fan modules and other actuators on command so you can confirm a part is actually responding before you replace it. Reset and calibration coverage includes Oil Service, EPB, SAS calibration, ABS bleeding, fuel injector matching, TPMS relearn, battery calibration and AFS calibration -- the common post-repair resets that otherwise send VAG owners to the dealer.

Software updates are included for the life of the tool over WiFi, no subscription. Supports 22 languages. Works with Android and iOS; service-function depth varies by model and year.
