Choose by the vehicles you will use it on, the systems or service functions you need and how often you expect to use it. A basic OBD2 reader suits engine warning-light checks. ABS, airbags, transmission, body modules and service functions normally require a suitable single-make or all-makes scanner.

The quickest starting point is the Product Selector or the scan-tool guide.

Compatibility depends on the exact tool, vehicle make, model, year, engine, original market and the system or function required. A scanner can communicate with one part of a vehicle without supporting every module or procedure.

For a specific check, send the full vehicle details and tell us exactly what you need the tool to do. A request such as “2018 Ford Ranger 3.2 diesel, ABS fault codes and ABS bleed” is much more useful than just “Does it work on Ford?”

No. The familiar socket is a useful clue, but it does not prove that a generic OBD2 reader will communicate correctly or that it can access systems beyond the engine. Older vehicles, Japanese imports and vehicles built for different markets can vary. See the OBD2 guide for more detail.

A basic OBD2 reader is mainly for standard engine and emissions fault codes, live data and warning-light checks. A full-system scanner can provide access to supported modules such as ABS, SRS airbags, transmission, body control and electronic parking brake, along with vehicle-dependent service functions.

No. Functions such as DPF regeneration, battery registration, injector coding, electronic parking brake, steering-angle calibration and active tests are vehicle-dependent. A tool supporting a function somewhere in its coverage does not mean the same function is available on every make, model and year.

Most standalone scan tools are not locked to one vehicle and can be used across the makes and models included in their coverage. Coverage still varies between vehicles. App-based products, specialist platforms or subscription services can have product-specific account or licence rules, so check the individual product page.

Not usually. A fault code identifies the circuit, system or condition the vehicle has detected. It does not automatically prove that the component named in the code is faulty. Wiring, power supply, vacuum leaks, mechanical faults and related sensors can produce similar symptoms. Codes and live data are the starting point for diagnosis, not a guaranteed parts list.

No. Clearing a code removes stored information and may turn off the warning light temporarily, but it does not repair the underlying cause. If the fault is still present, the code or warning light will normally return.

Not automatically. Motorcycles commonly need dedicated software and the correct brand-specific connector. Fitting a physical adapter to a car scanner does not create motorcycle coverage. Use a scanner specifically designed for the motorcycle makes you need.

Many do, but Japanese imports need a proper compatibility check. Protocols, model names, engines and module coverage can differ from NZ-new or export-market versions of what appears to be the same vehicle. Send the exact vehicle details and required function before ordering when coverage is important.

Update terms depend on the product. Many handheld scan tools include free manufacturer updates, while some app-based, professional or connected products can use subscriptions or platform fees. The individual product page should state the update arrangement. Contact us before ordering if that information is unclear.

It depends on the tool. Many handheld scanners work as standalone units once set up. Bluetooth and Wi-Fi products may need a compatible phone or tablet, while some tools require internet access for registration, software downloads, updates or online functions. Check the requirements on the product page.

Normal code reading and live-data use with a suitable tool should not damage the vehicle when the instructions are followed. Advanced functions can change vehicle settings or operate components, so only run procedures you understand. Keep vehicle voltage stable during software updates, coding and lengthy service functions, and never disconnect the tool partway through an instructed process.

Submit a return request with the order number, a clear description of the issue and any requested photos or video. Stahlcar products include a 12-month warranty against manufacturing faults during normal use. This sits alongside your rights under the New Zealand Consumer Guarantees Act.

We may troubleshoot the issue before arranging a return, as update, setup, power or compatibility problems can sometimes look like hardware faults.

Contact us before sending it back. An exchange may be available if the product is complete and remains in as-new, resalable condition. For a non-fault exchange, the customer normally pays the return shipping and any difference in product price.

Compatibility is vehicle and function dependent, so an automatic refund is not guaranteed simply because a tool does not perform an unstated function on a particular vehicle.

Change-of-mind returns are considered case by case and are not automatic. An approved return must be complete, undamaged and in as-new, resalable condition. The customer pays return shipping and a 15% restocking fee may apply to an approved refund.

The restocking fee does not apply to a valid fault claim where a remedy is required under the Consumer Guarantees Act.

No. Submit the request first and wait for the return address and instructions. Unapproved parcels can be difficult to identify and can delay the assessment.

Stahlcar provides written support for product selection, setup, updates, connection problems, coverage checks and use of supported functions. Support is provided by email or through the website contact form rather than by phone.

Written support lets you include vehicle details, screenshots, fault messages and photos, which are usually essential for scan-tool troubleshooting.

No. We can help you use the tool, understand what information it is showing and check whether a function should be available. A scan tool does not replace mechanical testing, wiring checks or an in-person diagnosis, and Stahlcar cannot confirm a repair from a fault-code description alone.

Please include as much of the following as possible:

• Order number and scan-tool model
• Vehicle make, model, year and engine
• Whether the vehicle is NZ-new or imported, if known
• The exact system or function you are trying to access
• The wording of any message or error shown
• Clear screenshots or photos
• The steps already tried and current software version

Contact us. The written warranty period does not automatically end any rights that may apply under the Consumer Guarantees Act. The appropriate response depends on the product, age, use and nature of the problem.

Damage caused by impact, liquid, misuse, incorrect connection, unauthorised modification or repair, or use outside the instructions is not normally covered where that damage caused the problem. Normal wear and consumable items are also treated differently from a manufacturing fault.

Yes, particularly if you may request a non-fault exchange or return. Keep the box, case, cables, adapters, manuals, inserts and all supplied accessories. Missing or damaged items can affect whether a non-fault return is accepted and the amount credited or refunded.
