Plugging a scanner into the OBD2 port under your steering wheel is one of the first steps a mechanic will take to diagnose customer complaints. By running a detailed scan, the tech can uncover any diagnostic trouble codes (DTCs) to narrow down the possible causes. OBD2 code readers, also known as scan tools, are more accessible to consumers than ever. If you don’t have one already, consider picking up this BlueDriver option while it’s $80 for Black Friday, or 33% off.
With more than 45,000 five-star reviews to date, the BlueDriver OBD2 scan tool has been praised by everyday shoppers and professional reviewers alike—and for good reason. For one, it comes in a much smaller package than most full-size scanners since it uses your iOS or Android device as its display. It’s also compatible with a variety of different apps with a range of features, making it a lot more flexible than a standard OBD2 reader. That said, the BlueDriver also comes with its own free app in case you’d rather not shop around for software.

As with dedicated OBD2 scan devices, the software provides real-time data on various components as you drive, detailed reports with common fixes reported by actual mechanics, and step-by-step instructions on how to perform the repairs yourself. In the event of a false alarm, it also lets you clear “ghost codes,” or check engine light flukes and DTCs that appear even when no such problem exists.
Compatible with every vehicle built since 1996, the BlueDriver scanner is a convenient way to diagnose problems on the fly. Not only can you keep it connected at all times, but all you need to do is break out your phone whenever you notice something wrong. It’s completely wireless and requires only a Bluetooth connection to start running scans. The car itself acts as its power source.
“Paid for itself in one use!” exclaimed one shopper. “It’s an easy plug-and-play device with an EXCELLENT app. The app provides details on the diagnostic codes and even tells you the frequency/rarity of the problem occurring in your make and model vehicle as well as provides links to parts that might be involved in repair. Helped me dx and solve a problem the first time I plugged it in and saved me a trip (and $$$$) to the auto shop. Five stars!”
