The Autel MaxiCOM MK900BT is a powerful, professional-level diagnostic scanner well suited for Audi vehicles and many other brands. It supports extensive compatibility with over 150 makes and 10,000 models from 1996 to 2025, including advanced protocols like CAN FD and DOIP used in newer Audi models. This scanner offers 3000+ active tests and 40+ service functions, enabling deep diagnostics such as reading and clearing codes, live data tracking, battery testing, and actuator testing. It can access all vehicle systems (ABS, SRS, ECM, etc.) and provides advanced features like bidirectional control and pre/post diagnostic reports, which help pinpoint issues more precisely.

Ease of use is enhanced by its large 8-inch touchscreen, auto VIN and license plate recognition, WiFi printing, and wireless diagnostics up to 33 feet, which means you don’t have to be cramped inside the car during testing. The device runs on Android 11 with a fast processor and long-lasting battery, offering a smooth and responsive experience. On the connectivity front, it supports WiFi and 4G, making updates and cloud storage of repair data seamless. Speaking of updates, it includes a one-year free update with optional paid subscriptions thereafter; language support spans 21+ languages.

Some high-end features like the battery tester and endoscope require additional accessories. While the tool covers a vast number of vehicles, some functions may not work on every model, so checking compatibility before purchase is important. The scanner is more costly than basic readers but delivers excellent value for professional mechanics or serious Audi enthusiasts who want comprehensive diagnostics and advanced service capabilities in one portable device.

The OBDeleven OBD2 Diagnostic Tool Scanner is designed for Audi, Cupra, Seat, Skoda, and Volkswagen vehicles, making it a versatile choice for owners of these brands. It's compatible with both Android and iOS, providing flexibility for users regardless of their smartphone preference.

The tool excels in its diagnostic functions, offering comprehensive error reading and clearing capabilities, which is essential for maintaining vehicle health. Ease of use is another highlight, with many users finding the interface intuitive, though some may experience a learning curve initially. Connectivity is a strong point, with the device easily connecting to smartphones via Bluetooth, ensuring seamless data transfer. However, it's worth noting that some users have reported occasional connectivity issues, which might require troubleshooting.

The product shines in its update and support, as the manufacturer, Voltas IT, regularly updates the software to include new features and enhance performance. The scanner is lightweight and compact, making it portable and easy to store. Despite its strengths, the OBDeleven scanner might be less appealing to those who prefer a device with a built-in screen, as it relies entirely on smartphone connectivity. For vehicle owners seeking a reliable, feature-rich diagnostic tool that's easy to carry and regularly updated, this could be a valuable addition to their toolkit.

The Innova SD35 OBD2 Scanner is a solid choice for anyone wanting to diagnose a wide range of vehicle issues beyond just the check engine light. It works with many cars and trucks from 1996 onward, including popular brands, though you should double-check compatibility with your specific Audi model using Innova’s Coverage Checker. This tool stands out with its ability to read codes from systems like ABS, SRS, and TPMS, offering a more complete diagnostic picture than basic scanners. The live data feature shows real-time engine info like RPM and temperature, which can be helpful for understanding how your car is performing.

The device runs as a tablet with a clear, high-resolution screen and pairs with a free app on your phone, making it easier to navigate and understand the results. There are no ongoing subscription fees, and it offers repair advice based on real-world fixes, a nice bonus for DIYers or those wanting to understand the problem better before heading to a mechanic.

Some features may not work on all vehicle models, so compatibility should be verified. Although it offers advanced functions like oil light resets and TPMS checks, it might not cover every service function an Audi specialist tool would provide. Additionally, the device weighs just over a pound, which is somewhat bulky compared to simpler handheld scanners. For those seeking a user-friendly scanner that goes beyond basic code reading and provides helpful repair guidance without extra subscription costs, the Innova SD35 is a versatile and easy-to-use diagnostic tool that suits many Audi owners who do not need highly specialized brand-specific features.
