VDIAGTOOL D100 Bluetooth OBD2 Scanner with Bidirectional Control

The VDIAGTOOL D100 is a Bluetooth OBD2 scanner with bidirectional controls, full-system scanning and more than 17 service reset functions claimed for supported vehicles. It pairs with iOS and Android phones and presents live vehicle data as graphs, making it suited to owners who want more than basic engine-code reading. Compatibility and reset availability vary by vehicle.

At a glance

Bidirectional actuation is intended to command supported vehicle components and observe module feedback, rather than only read fault codes.
The listing claims scanning of core modules including engine, ABS, SRS and TPMS, alongside standard OBD2 functions.
Live data can be shown, recorded and played back as eight graphs at once, according to the listing.
The listed reset examples include oil, EPB, battery management, TPMS, ABS bleeding and DPF/GPF regeneration. Availability depends on the vehicle.
The manufacturer claims permanent free software downloads and updates.

Pros and cons

Pros

Combines code reading and clearing with bidirectional component tests and broad system scanning claims.
Graphing, recording and playback of multiple live-data streams may help users compare vehicle readings over time.
Bluetooth pairing with both iOS and Android phones avoids a dedicated display being required.

Cons

Using the scanner requires a compatible smartphone and the VDIAGTOOL app.
Many advanced resets and active tests are vehicle-dependent, so the advertised function count does not mean every function works on every car.

What to know before buying

The listing claims OBD2/EOBD coverage from 1996 onward, but coverage of specific systems, protocols, resets and active tests varies by make and model. Confirm support for the exact vehicle and intended function before relying on it.

Who is it for?

A good fit for

Car owners who want phone-based diagnostics beyond engine codes, including live data and supported active tests.
DIY maintainers seeking service resets, provided their vehicle is explicitly supported for the required procedure.

Less suited to

Buyers who need a stand-alone scanner with its own screen or do not want to use a phone app.
Anyone who needs guaranteed support for a particular reset, vehicle module or programming procedure without confirming compatibility first.

Customer feedback reports ease of setup, bidirectional control, diagnostic capability, live data and compatibility as positives, while overall functionality receives mixed feedback. These impressions are relevant to the D100's phone-based active tests and data graphs, but they do not establish support for every vehicle or advertised reset. The aggregate rating is generally favourable but includes a meaningful spread of lower ratings, so buyers should treat vehicle-specific performance as uncertain.

Positive themes

Customers mention easy setup and bidirectional control.
Feedback highlights diagnostic functions, live data and compatibility.

Mixed feedback

Customers report mixed experiences with functionality.
