Everyone knows how imperative it is to service their vehicles to make sure they’re running smoothly and efficiently. But even if someone is following the manufacturer-suggested service intervals and keeping their car in good shape, the check engine light might show up and ruin the good feels that come with proper maintenance. But there’s no need to panic and take another costly trip to your mechanic. Running diagnostics on your own car is easy.

Your car has a computer system that monitors various other subsystems that make your car work. On-board diagnostics (OBD) tools allow you to check the status of your car’s subsystems without having to go to a mechanic. From diagnosing a check engine light to figuring out your fuel economy, there’s a lot an OBD scanner can do for you.

With Bluetooth devices, it gets even easier as you can now use your tablets or smartphones as dependable diagnostic scanning tools. Using apps that talk to a Bluetooth scanner plugged into your car’s computer, the interface of the diagnostic tool would be one you’re already used to.

While there are many types of OBD2 scanning tools, Bluetooth wireless scanners are much more convenient than traditional ones. They don't have screens or built-in code-reading software. Instead, they connect to any of dozens of diagnostic apps on your smartphone and display loads of information there. To help you pick an OBD2 scanner for your vehicle, we have compiled a list of the top 5 best Bluetooth OBD2 scanners.

For more information on Bluetooth OBD2 scanners, refer to our table of contents.

It also lets you reset service lights, including oil change lights, without a trip to the dealer. It can connect to iOS and Android phones, too. But the best part is the Advancer AD20 app that is designed to work with this particular dongle, giving you loads of live data streams, access to readiness tests that are crucial to government emissions testing, and other important functions.

    Why is OBDLink not in this list? It's better than all of them.
