2. Detailed Comparison: Autel MD802 vs MD805

When comparing the Autel MD802 and MD805, it’s essential to look at several key factors, including their diagnostic capabilities, vehicle coverage, user interface, hardware specifications, and price. This comparison will help you determine which scanner is the better fit for your specific needs.

2.1. Diagnostic Capabilities

Both the Autel MD802 and MD805 offer comprehensive diagnostic capabilities, but there are some important differences. The MD802 is capable of diagnosing all major vehicle systems, including the engine, transmission, ABS, and airbags. It supports all 10 OBDII test modes, allowing users to perform a wide range of diagnostic tests.

The MD805 builds on these capabilities with enhanced diagnostic functions and improved accuracy. It offers more detailed diagnostics for the same systems, often providing more specific information about the nature of the problem. Additionally, the MD805 may include advanced features such as bidirectional control, which allows users to send commands to vehicle systems to test their functionality.

2.2. Vehicle Coverage

Vehicle coverage is another critical factor to consider. The Autel MD802 has global OBDII coverage, meaning it is compatible with most OBDII compliant vehicles. However, its coverage for specific makes and models may be limited, especially for newer vehicles.

The Autel MD805 typically offers wider vehicle coverage, supporting a broader range of makes and models. This is particularly important for users who work on a variety of vehicles or who own newer cars. The MD805 is more likely to include the latest vehicle protocols and diagnostic capabilities, ensuring compatibility with modern vehicles.

2.3. User Interface and Ease of Use

The user interface is an important consideration, especially for users who are not experienced mechanics. The Autel MD802 has a straightforward interface that is relatively easy to navigate. However, it may feel somewhat dated compared to newer scanners.

The Autel MD805 is designed to be more user-friendly, with a more intuitive interface and improved navigation. It often includes features such as Auto VIN technology, which automatically identifies the vehicle make, model, and year, making the diagnostic process faster and easier. The MD805 also typically has a higher resolution display, making it easier to read data and view diagnostic information.

2.4. Hardware and Specifications

The hardware specifications of a scanner can affect its performance and durability. The Autel MD802 has a solid build quality and a decent display screen. However, its processing speed may be slower compared to newer models.

The Autel MD805 generally features improved hardware specifications, including a faster processor, more memory, and a higher resolution display. This results in faster scanning speeds, smoother operation, and a more responsive user experience. The MD805 may also include additional hardware features such as a built-in speaker for audible alerts and a more durable design.

2.5. Price

Price is always a significant consideration when choosing a diagnostic scanner. The Autel MD802 is typically less expensive than the MD805, reflecting its older technology and more limited features. This can make it an attractive option for users on a budget.

The Autel MD805, with its enhanced features and wider vehicle coverage, usually comes at a higher price point. However, many users find the additional cost to be justified by the improved performance, user-friendliness, and broader capabilities of the MD805.
