Collection: Car Diagnostics, OBD2 & ECU Coding

Explore our selection of automotive diagnostic tools, OBD2 readers, Bluetooth scanners, multi-brand scan tools and coding solutions. The range covers needs from basic engine fault-code reading to all-system diagnostics, bidirectional testing and certain coding functions depending on the tool and vehicle.

OBD2 reader, scanner or professional diagnostic tool?

A basic OBD2 reader may be enough to read engine fault codes. To work on ABS, airbags, transmission, body modules or other ECUs, choose a tool with broader system coverage.

Our guide to choosing an OBD2 diagnostic tool explains CAN FD, DoIP, bidirectional testing, AutoVIN and ECU coding.

CAN FD, DoIP and bidirectional testing

These functions can be essential on some newer vehicles, but they only matter if the exact model and ECU are supported. Always check the tool's real coverage before ordering.

VCDS and OBDeleven for VAG vehicles

For Audi, Volkswagen, Škoda, SEAT and Cupra, see our VCDS vs OBDeleven comparison, our VCDS coding page and our OBDeleven library.

Choosing a KINGBOLEN tool

The collection includes several KINGBOLEN ranges: simple OBD2 readers, Bluetooth scanners and more advanced diagnostic tablets. Compare the intended use, required ECUs, supported protocols and update conditions.

Before ordering

• Vehicle make, model, year and engine.
• The exact function you need.
• Protocols and ECUs you want to diagnose.
• Whether you need active tests, coding or secure-gateway access.
• Licence, subscription and update conditions.

Important: clearing a fault code does not repair the underlying cause. If the fault returns, continue the diagnosis.
