The Bozfnuq V520 Professional OBD2 scanner might have a quirky name, but it’s a serious contender in the world of affordable car diagnostic tools. Priced competitively, this handheld device packs a punch, offering the essential features needed to understand generic fault codes, turn off that pesky check engine light, and perform comprehensive I/M Readiness checks. What sets the V520 apart in the crowded market of OBD2 scanners is its innovative QR code feature for easy sharing of diagnostic reports, although it does fall short by not offering firmware updates or manufacturer-specific fault code access.
Is the V520 Obd2 Scanner truly a professional-level tool, or is it just a capable amateur-grade device with a budget-friendly price tag? Let’s dive into the details.
Pricing and Availability of the V520 OBD2 Scanner
Priced around $40, the V520 OBD2 scanner from BozFnuq strikes a compelling balance between affordability and functionality. It competes directly with budget scanners, yet offers a range of enhanced diagnostic capabilities that can be invaluable for troubleshooting vehicle issues. Interestingly, similar models are marketed under different brands like Garmee and Brangdy, suggesting a common origin with slight variations.

The V520 OBD2 scanner features a practical design dominated by a black housing accented with user-friendly orange buttons and clear white lettering. It feels comfortable to hold and operate, with a weight of 8.3 ounces placing it in a comfortable middle ground for handheld scanners of this size – not too heavy, not too light.
Dimensionally, the V520 is slightly more compact than comparable scanners like the Launch CR529, measuring 6.7 x 3.4 x 1.1 inches. The attached cable, at 33 inches, is designed for in-cabin use and may not reach engine bay diagnostic ports without an extension. However, it performed flawlessly with a 6-foot OBD extension cable during testing.
Oriented for vertical use, the V520 boasts a bright 2.8-inch color display that offers both light and dark display modes, a feature not always found in this class. While it lacks a touchscreen, the nine-button interface is intuitive and provides dedicated keys for I/M Readiness checks and battery voltage monitoring (BAT button). This combination allows users to proactively identify potential issues before they escalate.
Setting Up and Using the V520 OBD2 Scanner

Getting started with the V520 OBD2 scanner is remarkably simple. Plugging it into the OBD port of a Subaru Outback immediately powered it on, displaying a clear nine-tile interface on the screen. From there, accessing functions like pre-inspection checks, full vehicle scans, and battery status was straightforward.
However, the V520’s documentation is limited, consisting of a brief 13-page booklet. The supplementary YouTube video, while demonstrating key features, is basic and lacks in-depth instructions. This might be a drawback for users needing detailed guidance.
On the upside, the V520 comes with a three-year warranty, offering peace of mind. A significant limitation, however, is the absence of firmware update capability, meaning the scanner’s functionality cannot be expanded or improved over time.
V520 OBD2 Scanner Performance and Features

Beyond reading and clearing fault codes, the V520 OBD2 scanner excels at displaying a variety of live data parameters. This includes crucial information like engine speed, coolant temperature, throttle position, and airflow readings. The device can also graphically represent this data using simple line plots directly on its screen.
A standout feature of the V520 Professional is its ability to save any displayed screen or diagnostic report as a QR code. By scanning this code with a smartphone, users can easily access and share the information. This is particularly useful for documenting vehicle issues for mechanics or when assessing the condition of a used car.
In addition to the dedicated battery health check, the V520 can retrieve historical fault codes. However, it lacks more advanced features such as service bulletins or repair guidance. It is also unable to perform cylinder balance tests or reset service lights like the “Change Oil” indicator.
The dedicated I/M Readiness test key simplifies emissions pre-inspection checks. During testing, simulating a fault by disconnecting the driver’s occupant sensor module was successfully detected and recorded by the V520, and cleared once the sensor was reconnected, demonstrating its fault detection capabilities.
