Reading basic car data with a simple OBD2 scanner and an Android app is easy. However, accessing a modern car’s full computer suite and functions like oil level requires a more advanced tool. Budget-friendly options like a $13 Bluetooth ELM 327 dongle paired with a phone app are limited to OBDII scanning and won’t provide in-depth diagnostics. To access non-OBDII systems, a more sophisticated scan tool is needed.
Entry-Level Solution: Autel DiagLink
The Autel DiagLink, priced around $90-$100, offers a cost-effective entry point for accessing non-OBDII data. This tool allows functions like resetting oil change lights and controlling electric parking brakes. A key consideration with the DiagLink is its single-brand limitation. Upon purchase, it comes with free software for one specific car brand, requiring additional software purchases for other makes. While subsequent brand software costs around $10, this factor is crucial for users with multiple car brands.
Multi-Brand Solution: Autel MD806
For broader compatibility, the Autel MD806, priced around $200, provides a compelling solution. This scanner supports multiple car brands without requiring separate software downloads for each. It also boasts “lifetime” free software updates, although this typically refers to the tool’s expected support lifespan, not indefinite updates. The MD806 offers comprehensive functionality, catering to most home mechanics’ needs, making it a valuable investment for frequent use.
Choosing the Right Tool
Choosing between the DiagLink and MD806 hinges on individual needs. For single-brand car owners seeking advanced diagnostics, the DiagLink offers excellent value. Users with multiple car brands or anticipating future vehicle changes will find the MD806’s multi-brand support and lifetime updates more beneficial. Both tools surpass basic OBDII scanners, providing access to comprehensive vehicle data and advanced functionalities. While the “lifetime” update promise should be interpreted realistically, both the DiagLink and MD806 represent strong value propositions in the automotive scan tool market, empowering home mechanics with professional-grade diagnostic capabilities.
