Review on 🔧 2021 Autel Scanner MaxiCOM MK808: Advanced OBD2 Car Diagnostic Scanner with 25+ Maintenance Functions and Full System Diagnosis by Richard Bowens

I am a trained mechanic (I am writing this on behalf of my wife). This might be one of the best scanners in this price range and supports vehicles that many scanners like Volvo don't. It supports a wide range of modules that can be scanned for codes, as well as the ability to view sensor readings and data for the specific module being scanned. It's not the fastest way to scan and connect, but it's faster than many and the functionality is worth the few seconds wait. If you're looking for a truly bi-directional scanner this shouldn't be your choice, but if you only need data for testing or maintenance procedures this will be invaluable. The key coding seems very blurry and can only support BMW and Mercedes. So don't expect it to be able to code all the new keys your store needs or anything like that. VIN recognition is not 100%, so you can enter vehicle information from random vehicles. I haven't noticed any real pattern for this, and sometimes it doesn't recognize the VIN for cars it did earlier in the day, but it can after a few tries. One thing I don't like is that if a module doesn't connect or return a signal and that module is present in the vehicle, it doesn't tell you explicitly, which can lead to misdiagnosis by some less experienced technicians. Software updates are incredibly easy and relatively quick.
