This OBD reader has an amazing amount of diagnostic capabilities, I'm still finding out what I need to know. YouTube is a great help, almost overwhelming. I use the control app on an old 8 inch Android tablet and it suits my needs perfectly. Important! Don't assume this tool will do everything advertised with your car. It's not Xtool's fault. Therefore, before purchasing and if you are interested in a specific test or feature, please contact the Xtool team first. They will quickly let you know if the test is compatible with your vehicle. be simple and the answer should come quickly. In any case, I started discussing the possibilities of the reader with the people at XTool and quickly realized that they knew what they were talking about. No delays in getting detailed answers. Every time the person I spoke to answered my questions about Xtool's operation and capabilities, I had plenty of them trying to figure out if I should buy their D7/8 (now also D9) instead. I chose 30M because it does what I need and I won't have to pay to upgrade in a few years (big deal). I need an OBD reader with more functions, I'm going to the mechanic. This one hit me right.
