It’s important to note that while it supports gasoline and hybrid-electric vehicles, it’s not compatible with purely electric cars.
Diving Deeper into the Features
Now that we’ve got an overview, let’s dive a bit deeper into some specific features to see what makes this tool unique and beneficial for car owners.
Comprehensive System Scanning
Unlike many cheaper options that limit you to just engine codes, the AD20 Pro offers a full-system scan.
This means you can diagnose issues with multiple systems in your car including powertrain, steering, brakes, airbags, and tires. That’s a lot of diagnostics that empower you to have a detailed health check of your vehicle.
Effortless Oil Maintenance
Oil changes are routine, but the accompanying light resets can sometimes be tricky or require a visit to the shop. With the AD20 Pro, you can reset the oil light yourself in a few simple steps, saving time and money right away.
The Advancer AD20 App Experience
How does an app make a difference?
Here’s how: the AD20 Pro’s exclusive app is tailored for ease of use with customizable dashboards to focus on the data that matters most to you.
This means you can set up your smartphone to display only the metrics you’re interested in, whether that’s speed, engine load, or coolant temperature.
Performance & Trip Analysis
Ever wonder how efficiently you’re driving? The performance and trip analysis tools offer insight into metrics such as average speed, top speed, acceleration, and more.
This can be particularly useful for optimizing fuel consumption and identifying areas to improve your driving habits.
No Extra Fees
Many diagnostic tools require costly subscription fees just to access their basic functions. Thankfully, the AD20 Pro does not.
Once you’ve purchased the device, you’re free to use the app and all its features indefinitely—an important consideration for budget-conscious car owners.

Real-World Use and User Experience
Setting Up and Using the AD20 Pro
Setting up the device is straightforward. You need to download the Advancer AD20 app from either the Google Play Store or the App Store. Once installed, connect the scanner to your car and pair it with your smartphone via Bluetooth.
Instructions are clear and typically, the device is ready to use within minutes.
User Feedback and Reviews
Users have highlighted the simplicity and effectiveness of the AD20 Pro.
Many appreciate the feature set it offers—especially the oil light reset and the detailed system diagnostics that go beyond what cheaper devices can provide. The ease of understanding the app interface is also frequently praised.
Limitations and Considerations
No device is perfect, and it’s worth noting a few limitations of the AD20 Pro.
It’s not compatible with electric vehicles, which is something to keep in mind if you own or plan to purchase an electric car. Additionally, if multiple users share the device across different vehicles, routine unpairing and re-entry of vehicle information can be a minor inconvenience.

Troubleshooting and Tips
If you encounter connectivity issues, ensure that your phone’s Bluetooth is enabled and the app is properly installed. For any issues with the app, uninstalling and reinstalling might help. If problems persist, reach out to customer support for assistance.
Another tip is to regularly check for app updates to take advantage of any new features or improvements. This ensures your diagnostic tool stays current with the latest technology.
