OBD II Scanners

If you’re curious to see what’s going on with your car on the go, troubleshooting any sort of problem is impossible unless you use a proper diagnostic scan tool. If you own a car, be that Mercedes or a BMW, you should at least think of an OBD-II scanner to get quick access to specific info or erase that annoying check engine light.

Mercedes cars have a rather unique configuration in the OBD II serial parts. Therefore, many of them don’t work consistently with other non-BMW scan tools. The same goes for BMWs.

So, Mercedes or BMW owners who are looking to perform their own repairs and diagnostics might find their search a bit frustrating. That’s why we’re presenting you a list of the best OBD II scanners that you may pick up.

Note: Deals are subject to change. Keep in mind that the price tag often varies. We recommend going on the vendor’s website to check the price. Some of the products may be out of stock by the time you’ve made your purchasing decision. So, hurry up and hit the buy button.
