The Autel MaxiDiag Elite MD802 is a powerful diagnostic tool for diesel vehicles, especially Sprinters. It reads and resets OBDII codes, ABS and SRS warnings, and assists with brake bleeding. While it can’t modify values like the Mercedes STAR system, it offers valuable diagnostic capabilities for understanding Sprinter issues. Unlike simple mobile phone apps, the MD802 accesses more internal modules for in-depth diagnostics.

Setting Up Your Autel MaxiDiag Elite on a Sprinter
Before using the MD802, update its software to the latest version. However, back up the SD card first, as updates can alter functionality. Test the tool before updating; if it functions as needed for your Sprinter’s model year, an update might not be necessary.
To update, create an online Autel account and register your device using its serial number and password. Although online registration is required, updates are installed via PC software from the included CD. The software is Windows-compatible; Mac users might need WINE or a virtual machine. Autel offers free updates for the 802, potentially indicating the product’s maturity.

Vehicle Selection and Model Year Considerations
The MD802 supports multiple vehicles. After connecting to the OBDII port, select “Scan,” then your region (manufacturer’s location).
- Newer NCV3 Sprinters (2007+): Located under European>Sprinter. If needed, try USA>Chrysler>Sprinter.
- Older NCV3 and T1N Sprinters: Listed under USA>Chrysler>Sprinter.
Note: The MD802 may not read all parameters on brand new Sprinters. Autel prioritizes out-of-warranty vehicles.

Diagnosing Your Diesel Sprinter with the Autel MaxiDiag Elite
The MD802 scans for codes, provides descriptions, and plots engine stats in real time, accessing components beyond the reach of many mobile apps. Crucially, it resets ABS and SRS module errors.

Resetting SRS Warnings
Access SRS system diagnostics within the Body control unit group. The MD802 can identify and reset errors, such as those triggered by a disconnected seatbelt sensor.

Utilizing the OBDII Scanner
The MD802 reads generic OBDII and Sprinter-specific codes. With the ignition in position 2, it scans for active codes and offers descriptions. It also provides information on specific control modules, such as the engine control module (ECM).
Real-Time Diagnostics and Data Logging
The MD802 graphs engine stats, displaying single, dual, or merged graphs. Saving graph data allows for later “printing” via a PC connection using the Autel Print application.

Conclusion
The Autel MaxiDiag Elite MD802 is a valuable tool for Sprinter owners, particularly those with diesel engines. It offers comprehensive diagnostic capabilities, allowing users to read and clear codes, monitor engine parameters, and troubleshoot issues. While not a replacement for professional-grade tools, the MD802 provides significant functionality for diagnosing and maintaining your Sprinter.
