KINGBOLEN SOLOSCAN BMW Mini Bidirectional Scan Tool

A BMW, Mini and Rolls-Royce only diagnostic dongle that plugs into the OBD2 port and runs through the Ediag app on your phone -- there is no screen on the tool itself, so the phone is the display. It connects over Bluetooth 5.2 with about 33 ft of range. Coverage spans the BMW 1 through 8 Series, X and Z cars, M models, Mini Cooper variants, and Rolls-Royce Phantom, Ghost, Wraith, Dawn and Cullinan, on the standard 16-pin OBD2 port.

Where this earns its keep over a cheap code reader is module access past the engine controller. It talks to the transmission module, ABS, SRS, chassis and battery management systems, so after a battery swap or a brake job you can run the same BMS registration and ABS bleed sequence a dealer tool would run, instead of guessing whether the old module data is still being used. Four-in-one live data graphing lets you watch RPM, coolant temp, voltage and a fourth parameter together during a road test.

Bidirectional active tests let you command components directly from the app and watch the response -- fuel pump, cooling fans and other actuators on supported models -- which is how you tell a dead relay from a dead command. Reset functions cover oil service, EPB release, SAS calibration, ABS bleeding, injector coding and TPMS reset, reached from the all-system diagnostic menu after an Auto VIN scan. Updates are WiFi-delivered for the life of the tool with no subscription.

Works with Android 6.0+ and iOS 9.0+ and supports 22 languages. Service-function depth varies by model and year -- check your specific chassis before you buy if you need a particular reset.
