Eric had just replaced a ripped seat cushion in his 2015 Mercedes E400 when the dreaded SRS Warning Light came on.
Faced with notoriously high Mercedes shop rates, Eric decided to simply clear the message each time he started the car, despite the constantly illuminated airbag light.
When he took the vehicle in for a trade, the technician told him that the light would cost him around a thousand dollars to fix, but Eric knew it was just a simple stored code.
So, he ordered a specialized OBD2 scanner for Mercedes late one afternoon and had it in hand by the next morning.
Eric reset the indicator, saving hundreds of dollars in repair costs.
Now, with the latest software updates, he’s prepared to use the tool for future diagnostics on his Mercedes vehicles.
This article will guide you to the 2024 best OBD2 scanner for Mercedes Benz.
Does Mercedes Have OBD2
Mercedes Benz cars have had OBD2 ports since 1996.
This is because U.S. regulations require all cars sold in the country after that year to have OBD2 systems.
The OBD2 system helps mechanics and car owners check for issues in the car by plugging a diagnostic tool into a small port. This port is usually located under the dashboard, near the driver’s seat.
While most cars have this system, Mercedes vehicles are more complex and need a scanner that can do more than just basic checks.
A regular OBD2 scanner might only show engine problems, but Mercedes cars have advanced features like the Electronic Parking Brake (EPB) and Suspension Control Systems.
These systems control important parts of the car, and not all scanners can access them. So, to get the most out of your diagnostic tool, you need a scanner that can read all these special systems.
Otherwise, you may miss some important information about your car’s condition.

What Scanner to Use for Mercedes
Choosing the right OBD2 scanner for your Mercedes can make car maintenance much easier.
The ANCEL BZ700 is a top option in 2024, specifically made for Mercedes Benz, Sprinter, and Smart vehicles.
This scanner offers excellent diagnostic coverage and is easy to use, making it perfect for both professional mechanics and car owners who like to handle things themselves.
Covers All Major Systems
The BZ700 can diagnose a wide range of vehicle systems, including the engine, transmission, airbags (SRS), ABS, chassis, and more. This means it can find problems that basic scanners might miss, giving you full access to all of your car's important systems.
16 Reset Services
This tool comes with 16 special reset functions designed for Mercedes vehicles.
Some of these include resetting the oil service light, replacing electronic parking brake (EPB) pads, adjusting transmission settings, and performing DPF regeneration.
These reset features ensure that your Mercedes continues running smoothly after regular maintenance or any necessary repairs.
Battery Monitoring and Maintenance
Keeping your battery in good shape is essential for your car’s performance.
The ANCEL BZ700 offers real-time battery voltage monitoring and battery registration, which can detect battery problems and help register new batteries properly after replacement.
This feature is particularly useful for Mercedes owners, as newer models have more advanced battery management systems that require these extra steps.
Works With All Brands
Although it’s perfect for Mercedes, the BZ700 also works with other car brands.
You can use it to check engine lights, perform smog tests, and run EVAP system checks on different types of vehicles.
If you own more than one car, this tool is versatile enough to cover all of them.
Finally, the BZ700 comes with lifetime free updates, so it always stays up-to-date with the latest car technology.
This helps keep your diagnostics accurate, saving you time and money on repairs, and making your car maintenance more efficient.
Will the OBD2 Scanner Work on Mercedes
OBD2 scanner will work on a Mercedes, but it's important to understand that not all OBD2 scanners are the same.
While almost any scanner can read basic engine codes, only special scanners made for Mercedes Benz can read all the systems in the car.
Mercedes has more advanced systems like the Transmission Control Unit (TCU), the ABS (Anti-lock Braking System), the Airbag System (SRS), and the Body Control Module (BCM).
To check and fix problems in these systems, you need a scanner that’s built to handle more than just basic functions.
For example, if you’re trying to fix something with the Electronic Stability Program (ESP) or the way the transmission shifts gears (called Transmission Adaptation), a regular OBD2 scanner might not be able to help.
It won’t show you the right codes or give you the real-time data you need to solve the problem.
A scanner designed for Mercedes can find issues in these complex systems or clear trouble codes after you make repairs.
Will Any OBD2 Scanner Work on Any Car
While OBD2 scanners are designed to work with most cars, not every scanner will perform equally well on all vehicles, especially when it comes to high-end brands like Mercedes.
For example, a basic OBD2 scanner can read engine problems and emissions issues in many vehicles, but it might not be able to check or fix more complex systems in luxury cars like Mercedes.
Mercedes cars have special features. Automatic Transmission Adaptation helps the car shift gears more smoothly.
DPF Regeneration cleans the filter in diesel cars. AdBlue Reset helps reduce emissions in diesel engines.
These features require a more advanced scanner.
Basic scanners won’t be able to work with these systems, meaning they can’t provide complete diagnostics.
Additionally, some important functions in Mercedes, like Service Interval Resets (which remind you when it’s time for an oil change or maintenance) and Advanced Driver Assistance Systems (ADAS) (which include features like lane-keeping assistance and collision warnings), might not be accessible with a simple OBD2 scanner.
Conclusion
Using the right OBD2 scanner for your Mercedes not only helps you diagnose problems quickly but also saves you money on costly repairs.
A reliable scanner like the ANCEL BZ700 gives you access to advanced diagnostics without the need for frequent visits to the dealership.
