Accessing comprehensive vehicle diagnostics often requires more than a basic OBDII Bluetooth scan tool. While a $13 ELM 327 dongle and a phone app might suffice for reading basic OBDII codes, they lack the capability to access non-OBDII systems, such as oil level monitoring, which isn’t part of standard OBDII data. Tools like the VeePeak scanners explicitly state their limitation to OBDII scanning only. For deeper diagnostics, a more advanced tool is necessary.
Delving into Advanced Diagnostics: Beyond Basic OBDII
To access non-OBDII systems, a scan tool capable of communicating with the vehicle’s proprietary communication protocols is required, similar to how the VIDA/DiCE system works for Volvo vehicles. For a budget-friendly option with advanced capabilities, the Autel DiagLink, priced around $90-$100, offers a viable solution.
However, the DiagLink has a limitation: it works with only one car brand. Upon purchase, you choose one brand-specific software package from Autel, which needs to be downloaded and installed on the device. Accessing advanced features on other car brands requires purchasing additional software from Autel, at approximately $10 per brand. While this cost is relatively low, it’s an important factor to consider. The DiagLink excels in providing advanced functionality, such as resetting oil change lights and controlling electric parking brakes (for the chosen brand), at a price point where most competitors only offer basic OBDII scanning. This makes it a cost-effective choice for users dedicated to a single car brand.
Multi-Brand Diagnostics: The Autel MD806
For users needing to diagnose multiple car brands, the Autel MD806, priced around $200, provides a comprehensive solution. Sharing similar hardware with the DiagLink, the MD806 boasts software that supports multiple brands without requiring separate downloads for each. It also includes “lifetime” free software updates, although “lifetime” typically refers to the expected support lifespan of the device. While updates might not be available 15 years down the line, the MD806 still represents excellent value.
This scan tool caters to the needs of most home mechanics, offering a wide range of functions without a hefty price tag, especially for frequent users. Its ability to handle multiple car brands and offer advanced diagnostics makes it a standout choice. Whether you need to reset service lights, access proprietary systems, or perform in-depth troubleshooting, the MD806 offers a powerful and versatile solution for car diagnostics.
Conclusion: Choosing the Right Tool
Selecting the best OBDII scan tool depends on your specific needs and budget. If your focus is on a single car brand and you require advanced functionality beyond basic OBDII codes, the Autel DiagLink provides a cost-effective option. For multi-brand diagnostics and comprehensive features, the Autel MD806 presents a compelling solution with its broader compatibility and lifetime software updates. Consider your diagnostic needs and long-term requirements when making your decision.
