You’re trying to connect your shiny new Bluetooth OBD-II scanner to your European car, but you’re greeted with a frustrating “Can0 Device Not Found” error message. Don’t worry, this is a common issue and usually has a straightforward solution. This article will guide you through the potential causes and provide step-by-step instructions to get you connected and reading those diagnostic codes in no time.
Understanding the “Can0 Device Not Found” Error
Before we dive into solutions, let’s clarify what this error message means. Your car’s onboard computer communicates with various modules (engine, transmission, airbags, etc.) through a network called the Controller Area Network (CAN). Your OBD-II scanner acts as a bridge, allowing you to tap into this network and access valuable data.
The “Can0 Device Not Found” error typically indicates that your scanning device or app cannot establish communication with your car’s CAN bus. This could be due to several reasons, from a simple Bluetooth pairing issue to a more complex compatibility problem.
Common Causes and Solutions
Here’s a breakdown of the most frequent culprits behind the “Can0 Device Not Found” error and their corresponding fixes:
1. Bluetooth Connection Issues
The most obvious culprit is a hiccup in the Bluetooth connection between your phone or tablet and the OBD-II scanner.
Solution:
- Ensure Bluetooth is Enabled: Double-check that Bluetooth is turned ON on your device.
- Forget and Re-pair: Sometimes, the connection gets glitchy. Try “forgetting” the OBD-II scanner from your device’s Bluetooth settings and then re-pairing it.
- Check Scanner Visibility: Make sure your OBD-II scanner is discoverable. Some scanners have a specific button sequence for this.
2. Incompatible OBD-II App
Not all OBD-II apps are created equal. Some apps are designed for specific car makes or models, while others may not be compatible with your car’s communication protocols.
Solution:
- App Store Research: Check user reviews and descriptions on the app store to see if others have reported compatibility issues with your car model.
- Alternative App: Try downloading a different OBD-II app, preferably one that explicitly mentions compatibility with European cars. Torque Pro and OBD Fusion are popular options.
3. Faulty OBD-II Scanner or Port
A malfunctioning OBD-II scanner or a damaged OBD-II port on your car can also prevent a successful connection.
Solution:
- Visual Inspection: Examine the OBD-II scanner and your car’s OBD-II port for any visible damage, such as bent pins or debris.
- Test Another Vehicle: If possible, try connecting your scanner to another vehicle (ideally a European model). This helps isolate whether the issue lies with the scanner itself.
4. Car Compatibility Issues
Certain European cars, especially older models, may have unique communication protocols that are not supported by all OBD-II scanners or apps.
Solution:
- Consult Your Owner’s Manual: Your car’s owner’s manual often provides information about OBD-II compatibility and any specific requirements.
- Online Forums: Online forums dedicated to your car make or model can be valuable resources for finding compatible scanners and apps.
5. Ignition Setting
Some cars require the ignition to be in a specific position (usually “On” but not necessarily running) for the OBD-II port to be active.
Solution:
- Ignition Cycle: Try turning the ignition ON (without starting the engine) and then attempting to connect your scanner.
- Check Owner’s Manual: Refer to your car’s owner’s manual for the correct ignition setting for OBD-II communication.
Still Can’t Connect?
If you’ve exhausted the above troubleshooting steps and still encounter the “Can0 Device Not Found” error, there’s a chance of a more technical issue with your car’s electronics or wiring.
Recommendation:
- Professional Assistance: It’s best to seek professional help from a qualified mechanic or an auto electrician who specializes in European cars. They have the knowledge and tools to diagnose and repair any underlying problems.

Frequently Asked Questions (FAQ)
1. Why am I suddenly getting the “Can0 Device Not Found” error when it used to work?
- Software Updates: Updates to your phone’s operating system or the OBD-II app can sometimes cause compatibility issues.
- Battery Disconnection: Disconnecting your car’s battery can reset some electronic settings, potentially affecting OBD-II communication.
2. Does the “Can0 Device Not Found” error mean my car has a serious problem?
- Not necessarily. In most cases, it’s a connectivity issue rather than a major mechanical or electrical fault.
3. Can I use any Bluetooth OBD-II scanner with my European car?
- While many scanners are compatible, some European cars require scanners that support specific communication protocols. It’s crucial to check for compatibility before purchasing.
Conclusion
Troubleshooting a “Can0 Device Not Found” error when using a Bluetooth OBD-II scanner on your European car can be a straightforward process. By systematically checking the connection, app compatibility, and your car’s settings, you can often resolve the issue yourself. However, if the problem persists, don’t hesitate to seek professional assistance to avoid any potential complications. Remember, a properly functioning OBD-II scanner is a valuable tool for understanding your car’s health and performance.
