Owning a Mercedes Benz means maintaining its performance and avoiding unnecessary repairs. To do that, having the right scan tool is essential.
But how do you pick the right one? It comes down to choosing a tool that offers the right features and works well with your vehicle.
The best scan tool for a Mercedes-Benz isn’t just about reading error codes. It should be able to easily communicate with your car’s systems and give you useful information for maintenance and troubleshooting.

Can a Regular OBD2 Scanner Work on a Mercedes
Regular auto scanner can be used on a Mercedes-Benz, but it’s only useful for basic diagnostics.
These scanners are built for standardized functions, so while they can pull common engine fault codes, they typically can't dive deep into the more advanced systems that make your Mercedes unique.
A regular OBD-II scanner might alert you to an engine issue or an emissions problem, but it won’t help with diagnosing specialized systems like the Airmatic suspension, 7G-Tronic transmission, or the Distronic Plus, which are standard in many Mercedes models.
Standard OBD2 scanners don’t have access to the manufacturer-specific codes that are key for a detailed diagnosis.
Without them, you’re left with a very basic overview of potential problems, limiting your ability to fully troubleshoot your vehicle’s performance.
Mercedes Scanner Is Indispensable
Unlike standard OBD2 scanners, Mercedes-specific diagnostic tools are designed to interact with the proprietary systems that Mercedes vehicles use.
These systems go beyond the engine and transmission to include features like airbag systems, seat memory, steering angle sensors, and more.
If you encounter an issue with your SRS (Supplemental Restraint System), a basic OBD2 scanner won’t be able to provide detailed information or clear the fault codes.
A Mercedes-specific tool will not only identify the issue but also allow you to reset the system after repairs.
Similarly, if your vehicle has problems with the COMAND infotainment system, only a Mercedes-compatible tool can access the necessary control units to diagnose and fix the problem.
STAR Diagnostic Tool VS. ANCEL V6 Pro
The STAR Diagnostic Tool is the official device used by Mercedes-Benz dealerships and service centers.
It offers a broader range of diagnostic capabilities than regular OBD-II scanners, including access to manufacturer-specific codes, advanced diagnostics, coding, and module reprogramming.
This makes it especially useful for working with the complex systems in Mercedes vehicles.
However, the STAR tool comes with a higher cost and requires a subscription for software updates.
It is also more complex to operate, which means it's generally a better fit for professional mechanics than for everyday car owners.
For those who don't need the extensive functionality of the STAR tool, more affordable options like the ANCEL V6 Pro+ offer many useful features without the high cost.

Key Features of Mercedes Scan Tool
Full System Diagnostics: Your scanner should be able to diagnose all systems in the car, not just the engine and transmission.
This includes ABS, SRS, BMS, TPMS, air conditioning, and body control modules.
A comprehensive tool will scan and report on every ECU (Electronic Control Unit) in the vehicle.
-
Live Data Streaming: This feature allows you to see real-time data from the vehicle’s sensors and systems. For example, you can monitor fuel trims, oxygen sensor performance, and throttle position in real-time, which is crucial for accurate diagnostics.
-
Bi-Directional Control: Also known as active testing, this feature allows the scan tool to send commands to various vehicle systems to test their functionality. For example, you can command the cooling fan to turn on or initiate a fuel injector test to check their performance.
-
Coding and Programming: Mercedes vehicles often require coding to enable new features or program replacement parts. A good scan tool should offer coding capabilities, allowing you to customize settings, enable new functions, or program new control modules.
-
Service Functions: Look for tools that offer service resets, oil light resets, and brake pad resets, as these will save you a trip to the dealer for routine maintenance tasks.
The ANCEL V6 Pro+ stands out as one of the best scan tools for Mercedes-Benz due to its wide range of features and affordability.
It supports full system diagnostics, bi-directional control, coding, and programming.
Additionally, it includes advanced functions like key programming, which allows you to add new keys without visiting the dealership.
The ANCEL V6 Pro+ can access all Mercedes control modules, including ABS, SRS, TPMS, airbags, and more.
It also offers live data streaming, which is crucial for diagnosing real-time issues. With a large, easy-to-read interface and no subscription fees, the V6 Pro+ is a fantastic alternative to more expensive tools like the STAR system.

Pick the Right Scanner for Mercedes Issues
Choosing the right Mercedes scan tool depends on your specific needs:
If you’re a professional mechanic or a serious DIYer, you’ll need a tool that can perform full system diagnostics, including coding and bi-directional control. The ANCEL V6 Pro+ is a strong contender in this category.
If you’re a casual car owner who only needs to clear fault codes and reset service lights, a more basic OBD2 scanner may suffice. However, these tools won’t provide the in-depth diagnostics required for many Mercedes systems. Check Ancel BZ700 car scan tool for BENZ!
Budget is also a factor. While the STAR tool is the most comprehensive option, it’s often out of reach for casual users due to its high cost and subscription model. For a more affordable yet feature-rich tool, the ANCEL V6 Pro+ is an excellent choice.
Advanced Features for Mercedes
Many advanced Mercedes scan tools provide important coding and programming functions.
When replacing a sensor or control module, the component typically needs to be programmed to ensure it functions correctly with the vehicle’s existing systems.
Tools like the ANCEL V6 Pro+ enable this programming, allowing users to handle these tasks on their own without needing to visit a dealership for assistance.
Additionally, coding allows owners to modify specific features, such as adjusting the auto start-stop function, enabling convenience windows, or customizing light settings.
This level of control and customization is only available with advanced diagnostic tools, making them a must-have for serious Mercedes owners who want to personalize and maintain their vehicles effectively.
How Do You Update a Mercedes Scan Tool
To keep your Mercedes scan tool functioning at its best, you need to ensure it stays updated.
ANCEL V6 Pro+ offer free 2 years updates, which are critical for ensuring compatibility with new Mercedes-Benz models and the latest diagnostic protocols.
Updates are typically available via USB or Wi-Fi, and they can be installed by connecting the tool to a computer or directly through the tool's interface.
It’s important to regularly check for updates, as new software versions may include additional features, bug fixes, and compatibility improvements that can enhance the performance of your scan tool.
