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 OBDLink MX+ is a versatile Bluetooth OBD2 scanner compatible with iPhone, Android, and Windows devices, making it a strong choice for Audi owners seeking a straightforward way to diagnose their car from a smartphone or PC. It supports a wide range of diagnostic functions beyond basic engine codes, including ABS, SRS, and TPMS, features that are often absent in scanners within this price range. This capability makes it useful for more detailed troubleshooting and maintenance. The adapter works with popular automotive apps like FORScan and Torque, offering flexibility in how data is viewed and interpreted. Setup and use are generally user-friendly, and its wireless Bluetooth connection offers convenience over wired alternatives, with reliable connectivity within typical vehicle cabin distances.

A notable advantage is the enhanced OEM support for brands such as Ford, GM, Mazda, and importantly for Audi’s parent group vehicles, allowing access to manufacturer-specific data more effectively than generic scanners. Firmware updates are provided regularly to keep the tool up to date with new vehicle models and features. Battery drain protection helps prevent car battery issues during use. While some advanced live data may require additional app knowledge or research for beginners, and it may not be as comprehensive as dedicated dealer-level Audi diagnostic tools, this scanner remains a reliable and easy-to-use option for Audi owners who want more than basic engine codes and appreciate the convenience of wireless diagnostics.

The Autel MaxiCheck MX808S is a powerful and fast automotive diagnostic scanner designed mainly for home mechanics and small repair businesses.

It also features 3000+ active tests and 28+ service functions like oil reset, ABS bleeding, and battery management, which are handy for routine car maintenance and troubleshooting. The ability to perform bi-directional control means it can send commands to vehicle parts for testing, a useful feature often found on more expensive tools.

Ease of use is enhanced by a 7-inch touchscreen with a clear display and quick auto VIN recognition that speeds up scanning. Some advanced services may not work on all vehicles or require extra purchases, such as FCA AutoAuth for certain Chrysler, Jeep, and Dodge models. Software updates are free for one year, with paid options afterward, which is typical but important to keep in mind for long-term use. The scanner is somewhat bulky and heavier than simpler handheld models, and some functions may require manual VIN entry or compatibility checks.

The Autel MaxiCheck MX808S is a feature-rich, fast, and versatile scanner ideal for those who want comprehensive diagnostics and service functions without the dealer’s cost. It fits best users who work with a variety of vehicle makes and want a robust tool that grows with their skills, though occasional compatibility checks and possible extra fees for advanced features should be considered.
