OBD (On-Board Diagnostics) scanners come in two types: generic and OEM-specific. All vehicles manufactured since the late 1990s are required to support generic OBD access. This type of access allows for reading and clearing basic engine-related fault codes and performing simple functions such as resetting the check engine light. While sufficient for minor issues like misfires, generic scanners lack the capability to diagnose complex problems related to other vehicle systems. They provide no access to controllers for the transmission, airbags, or climate control.
Each car manufacturer also utilizes unique OEM-specific codes that offer more detailed diagnostic information. Unfortunately, inexpensive generic code readers cannot interpret or clear these codes. Furthermore, each manufacturer employs a different interface, meaning a scanner designed for Ford vehicles won’t work on a BMW.
Professional-grade scan tools can access OEM-specific data for most or all car manufacturers, but their price tag often ranges from $2,000 to $5,000. However, there’s a more affordable option for BMW owners: the Foxwell NT510/520. Priced around $150, this scan tool stands out for its multi-manufacturer compatibility. It allows users to purchase and install individual software packages for approximately $60 each, expanding its functionality to cover various car brands.
The BMW software package for the Foxwell NT510/520 is exceptional. It provides comprehensive access to virtually every control module in the vehicle, including the engine, transmission, brakes, ABS, traction control, airbags, audio system, navigation, climate control, locks, and alarm system.
For BMW owners seeking a powerful yet budget-friendly diagnostic solution in 2018, the Foxwell NT510/520 is the clear winner. The initial $150 investment includes one OEM-specific software package. So, if you only require a BMW scan tool, the total cost remains at $150. This excellent scanner offers significant value and can quickly pay for itself through DIY diagnostics and repairs.
