If you have a Mercedes, you’re lucky enough to own one of the best vehicle brands in the world. But having a Mercedes doesn’t mean that you don’t need to be concerned with vehicle troubles.
One of the best ways to get an insight into your car’s engine health is to use a vehicle code scanner. This tool gives you an overview of errors, warnings, and codes stored in your car’s ECU (Electronic Control Unit).
If you don’t know what the ECU does, it acts as the “brain” of your car. All the sensors and components communicate with the ECU so that the engine can function and run smoothly. OBD2 is a vehicle communication protocol standard developed by the SAE. It allows for a diagnostic interface between an onboard vehicle computer and a diagnostic or service center.Â
We have tested several OBD2 scanners and created a list of the top 6 OBD2 scanners for Mercedes.

FAQ
What is an OBD2 scanner?
An OBD2 scanner is a device used to read and interpret the codes given by your vehicle’s computer. A code can be displayed in one of several ways, but the most common way is through blinking lights on your car dashboard. These lights are known as the Malfunction Indicator Lamp (MIL).
Why should I use an OBD2 scanner?
The main reason why you need an OBD2 scanner is that it allows you to reset check engine lights. In some cases, the problem might be minor and not require repair, but only a mechanic will be able to tell you this. If your car has a serious problem, like a catalytic converter failure or a major fuel leak, clearing the error code will delay any repairs. However, this is better than driving around with a check engine light on all of the time because it means your car isn’t safe to drive.
Which car make does it work for?
The OBD2 scanner works with any car model made after 1996. The more recent models are more likely to have the required technology installed. As long as you have an OBD2 port on your car, you should be able to use a Mercedes-specific scan tool.
Final Words
You’re probably wondering what makes a Mercedes OBD2 scanner the best choice for you. Well, that depends on what you need to accomplish!
When considering which OBD2 scanner to purchase for your Mercedes, it’s important first to ask yourself what type of functionality you want. If you’re looking for something for basic diagnostics, something like the BlueDriver Bluetooth Pro scanner is a great choice. However, if you have a newer Mercedes model, a FOXWELL NT301 Code Reader is the best choice.
