For car owners and enthusiasts alike, understanding your vehicle’s health is paramount. Since the late 1990s, OBD (On-Board Diagnostics) systems have become standard, offering a window into your car’s inner workings. However, not all OBD access is created equal. You’ll encounter two main types: generic and OEM-specific, and understanding the difference is crucial when choosing the right diagnostic tool.
Generic OBD2 access is mandated for all cars manufactured from the late 90s onwards. This provides a standardized way to retrieve a limited set of engine-related fault codes. With a basic, inexpensive OBD2 scanner, you can access these generic codes, perform simple functions like clearing engine fault codes, and turn off the dreaded Service Engine Soon (SES) light. For straightforward issues like a misfire, a generic scanner might suffice. However, for more complex problems, especially those beyond the engine itself – such as turbocharger faults – generic access falls short.
These basic scanners are designed to read engine codes and nothing more. They provide absolutely no insight into the multitude of other control modules within modern vehicles. Systems like the transmission, airbags, ABS (Anti-lock Braking System), climate control, and more remain completely inaccessible to generic OBD2 tools.
Car manufacturers, known as Original Equipment Manufacturers (OEMs), also implement their own proprietary, OEM-specific diagnostic codes. These codes are far more detailed and precise than generic codes, offering a deeper understanding of vehicle issues. The “cheap” generic code readers you find readily available simply cannot decipher or reset these valuable OEM-specific codes. Each manufacturer employs a unique communication protocol, meaning a scanner designed to access Ford’s OEM-specific data will generally be incompatible with the OEM systems of other brands like BMW, Toyota, or Mercedes-Benz.

Professional-grade diagnostic scanners bridge this gap, offering access to OEM-specific information across a wide range of manufacturers, sometimes even covering all of them. These comprehensive scanners empower mechanics to diagnose and repair issues in virtually any vehicle system. However, this extensive capability comes at a significant cost, with professional scanners typically ranging from $2,000 to $5,000. While these are essential tools for professional garages, the price point is prohibitive for most car owners and DIY enthusiasts.
There are some exceptions to this high-cost barrier. For example, Peake Research offered specialized, more affordable tools specifically for BMW vehicles, priced around $150. These tools provided deeper access than generic scanners but were limited to a single brand.
However, for those seeking a truly versatile, low-cost solution that approaches the capabilities of a professional scanner, the Foxwell NT510/520 (and newer models like NT530) emerges as a standout option. Priced around $150 initially, the Foxwell NT510/520 scanner breaks the mold by supporting multiple OEM-specific software packages. This means you can purchase and load software for various car brands onto a single device, typically for around $60 per additional brand.

The BMW software package for the Foxwell NT510, for instance, is particularly impressive. It grants access to an extensive array of BMW control units, going far beyond just the engine computer. You gain diagnostic and service functions for systems throughout the vehicle, including:
- Engine
- Transmission
- ABS (Anti-lock Braking System)
- Traction Control
- Airbags
- Audio System
- Navigation
- Climate Control
- Central Locking System
- Alarm System
- and much more
This level of access rivals that of professional-grade scanners, but at a fraction of the cost. The initial $150 purchase of the Foxwell NT510/520 includes one free OEM-specific software package of your choice. Therefore, if your primary need is a comprehensive BMW scanner, $150 could be your total investment for a tool that can pay for itself many times over.
In conclusion, for individuals seeking an “Obd2 Scanner That Does Everything” without breaking the bank, the Foxwell NT510/520 (or newer models in the NT5xx series) presents a compelling option. It offers a unique combination of multi-OEM support, deep diagnostic capabilities, and affordability, making it an excellent choice for both DIY car enthusiasts and professional technicians looking for a cost-effective supplemental scanner. While professional scanners remain the ultimate tools for comprehensive diagnostics across all brands, the Foxwell NT510/520 and similar multi-system scanners provide an exceptional balance of features and value, bringing advanced diagnostic power within reach of a wider audience.
