MD802: Distinguishing Itself from Other Autel Scanners
Choosing the right diagnostic tool can be challenging, especially with Autel offering a range of excellent scanners. Understanding the differences between models like the MD802, MD808 Pro, and DS708 is crucial to making an informed decision.
MD802 vs. MD808 Pro
While both are excellent full-system scanners, the MD808 Pro is often seen as an upgraded version of the MD802. The MD808 Pro typically includes additional service functions like oil reset, EPB, BMS, SAS, and DPF reset, which are not standard on the MD802. For users needing these extra maintenance features, the MD808 Pro might be a more suitable choice. However, for core diagnostic functions across all systems, the MD802 remains a highly capable and cost-effective option.
MD802 vs. Maxicheck Pro and MOT Pro EU908
The original article includes comparisons with Maxicheck Pro and MOT Pro EU908, suggesting these are tools in a similar class. Maxicheck Pro, like the MD802, is a multi-system scanner, but often with a focus on specific systems or brands depending on the version. The MOT Pro EU908, geared towards the European market, may have specific European vehicle coverage advantages. The MD802, however, aims for a broader global vehicle coverage and comprehensive system diagnostics at a competitive price point.

MD802 vs. DS708
The Autel DS708 (or MaxiDAS DS708) is a more advanced, professional-level diagnostic system, often featuring a larger screen, more advanced functions, and potentially broader vehicle coverage. The DS708 is typically priced higher and targets professional workshops needing advanced capabilities like ECU coding and programming, which are beyond the scope of the MD802. The MD802 is designed to be more user-friendly and affordable, catering to a wider range of users who need robust diagnostics without the complexity and cost of a high-end professional tool.
