Reading oil levels and interacting with a car’s full computer suite requires more than a basic OBDII scanner. A simple Bluetooth dongle and phone app, while sufficient for basic diagnostics, lack the capability to access non-OBDII systems. This article explores two of the best OBD scan tools for advanced diagnostics and tasks like resetting oil change lights: the Autel DiagLink and MD806.
Beyond Basic OBDII: Why You Need a Powerful Scan Tool
OBDII scanners primarily focus on engine diagnostics and emissions-related data. However, tasks like checking oil levels or manipulating electronic parking brakes require access to manufacturer-specific systems beyond the scope of OBDII. While a budget-friendly Bluetooth OBDII adapter might suffice for reading basic trouble codes, it won’t provide comprehensive access to vehicle data. Tools like the VeePeak, while excellent for OBDII scanning, are limited in this regard.
Autel DiagLink: Affordable Single-Brand Solution
The Autel DiagLink, priced around $90-$100, offers a cost-effective entry point into advanced diagnostics. This tool allows access to non-OBDII systems but is designed for a single car brand. Upon purchase, users choose one brand-specific software package to download and install on the device. This allows for in-depth diagnostics, including functions like resetting oil change lights and controlling electronic parking brakes, but only for the chosen brand.
While limited to a single brand, the DiagLink offers significant value. Additional brand software packages can be purchased for around $10, making it adaptable if you own multiple vehicles of the same make. For dedicated single-brand use, it provides functionality comparable to much more expensive tools.
Autel MD806: Multi-Brand Versatility
For users requiring multi-brand compatibility, the Autel MD806, priced around $200, provides a comprehensive solution. While potentially using similar hardware to the DiagLink, the MD806 boasts software supporting multiple car brands without requiring separate downloads for each. This tool also includes “lifetime” free software updates, ensuring compatibility with newer vehicle models for an extended period.
It’s important to note that “lifetime” updates typically refer to the expected support lifespan of the tool, not indefinite updates. However, the MD806 represents excellent value, providing extensive diagnostic capabilities for various car brands without a hefty price tag. It’s a valuable tool for home mechanics or anyone needing comprehensive diagnostic functionality across multiple vehicles.
Conclusion: Choosing the Best OBD Scan Tool for Your Needs
Choosing between the DiagLink and MD806 depends on individual needs. For single-brand users seeking advanced functionality at a budget-friendly price, the DiagLink excels. The MD806 caters to users requiring multi-brand compatibility and ongoing software updates, representing a robust investment for comprehensive vehicle diagnostics. Both tools offer significant value compared to basic OBDII scanners, providing the capability to delve deeper into vehicle systems and perform advanced tasks like reading oil levels and interacting with non-OBDII components.
