All-Makes, All-Systems Diagnostics Built for NZ Drivers
The UDIAG A500NZ is a capable all-makes diagnostic scan tool designed for users who want broad vehicle coverage, full-system diagnostics, and a strong range of service functions in a straightforward handheld unit. It is built for the New Zealand market and gives DIY users, mobile technicians, and workshops access to deeper diagnostics without stepping into high-end tablet pricing.
With support for all major vehicle systems, over 40 service and maintenance functions, live data, and broad brand coverage, the A500NZ is a strong step up from basic OBD2 scanners and entry-level code readers.
Best Suited For
The A500NZ is best suited to serious DIY users, small workshops, mobile mechanics, and anyone who works across a mix of makes and models. It is a good fit if you want one tool to handle engine, transmission, ABS, airbags, and other supported systems across a wide range of vehicles.
It is also a practical choice if you want service reset capability such as oil reset, EPB, DPF, battery registration, injector coding, and similar maintenance functions, while keeping the tool simple and handheld.

System Diagnostics
The A500NZ provides access to key vehicle systems including engine, transmission, ABS, SRS airbags, body control systems, and other supported modules. It allows you to read and clear diagnostic trouble codes, view live data, and use system information to help track down faults more accurately.
This makes it much more capable than a basic OBD2 reader, which generally only accesses engine-related fault codes.
Service Functions
The A500NZ includes over 40 service and maintenance functions. Supported functions include oil and service reset, electronic parking brake reset, DPF regeneration, battery registration, throttle alignment, steering angle calibration, injector coding, ABS bleeding, and more.
Function availability depends on the vehicle make, model, year, and system support, so not every function will be available on every vehicle.
Vehicle Compatibility
The A500NZ supports a wide range of American, European, Asian, and Australian vehicles, including Holden and Australian Ford coverage. It is designed for broad all-makes diagnostics and is suitable for many petrol and diesel vehicles fitted with standard diagnostic connections.
Coverage varies by vehicle, system, and function, especially on older vehicles and imports, but the A500NZ is one of the stronger value all-makes options in the Stahlcar range.

Is This the Right Scan Tool for You?
The A500NZ is a good choice if you want a capable all-makes scan tool with full-system diagnostics and useful service functions, without moving into the price range of professional tablet tools. It gives strong coverage and a practical feature set for serious home use and light workshop work.
If you only need to read engine fault codes, a basic OBD2 scanner may be enough. If you need advanced coding, programming, or higher-end workshop capability, one of our professional tablet tools may be a better fit.
