We only sell devices that are widely used and tested on Mercedes, Audi, VVW, Porsche vehicles,ect. Each product page includes a detailed compatibility list. If you are unsure, just contact us with your car’s VIN number and we’ll confirm compatibility before you buy. This way, you’ll never waste money on the wrong tool.

That’s exactly why we bundle books, guides, and support services with our products. Unlike other sellers, we don’t just ship you a device—we help you master it. You’ll get step-by-step instructions, and the option to book one-on-one remote support. With AutoExplain, you won’t be left alone.

We only sell tested and verified devices that work with official diagnostic software like Xentry, ODIS, WIS,etc. Every unit is checked before shipping. While some tools on the market are cheap clones with unstable performance, our devices are stable, reliable, and guaranteed to work. Many professional workshops already use the exact same tools.

Most guides on the market are nothing more than screenshots and short notes, leaving you to figure things out on your own. Our books are completely different—they provide step-by-step, in-depth explanations that walk you through every function of the software, not just pictures of menus.

And if you don’t have a strong background yet, don’t worry. We’ve built a dedicated support group where you can ask questions, get clarifications, and receive guidance until you feel confident using the software smoothly.

At AutoExplain, we don’t just hand you a book—we stand by your side to make sure you succeed.

Yes! We offer remote support services for setup, ECU coding, programming, and troubleshooting. Many customers come back to us not just for products, but also for ongoing support. You’re not just buying a book or a device—you’re joining a community of technicians who get real help when needed.

We carefully test and pack each device before shipping. However, if the issue is caused by our packing or during transportation, AutoExplain will take full responsibility and refund you. Simply contact us within 3 days after receiving the product, and we’ll make it right—no hassle. Your investment is protected.

Unlike generic sellers, we specialize in diagnostic tools and training. Every product you buy here comes with detailed learning resources and access to expert support. On Amazon/eBay you only get the hardware, with no real help. With AutoExplain, you get the full package: tools + knowledge + support.
