It can be frustrating when your new Obd2 Bluetooth Diagnostic Car Scanner Reader Tool seems to connect to your car and stream live data, but fails to read any trouble codes. Many car owners are turning to affordable options like ELM327 Bluetooth adapters paired with smartphone apps for DIY diagnostics. You might have purchased an ELM327 OBD2 Bluetooth OBD-II car diagnostic scan reader tool, similar to the mini version available online, hoping to read diagnostic trouble codes from your vehicle, like ABS issues indicated by a warning light.

If you’re experiencing a situation where your OBD2 scanner connects via Bluetooth, shows real-time data such as RPM and speed, but doesn’t display any fault codes when using apps like Car Scanner on your Android device, you’re not alone. Several factors could be at play.
Firstly, while the ELM327 interface is widely compatible, issues can arise, particularly with clone devices. Although your adapter seems to be communicating, its ability to retrieve all diagnostic data, including trouble codes, might be compromised. Secondly, the app itself could have limitations or require specific settings to properly read codes from your car’s make and model. It’s worth verifying that the Car Scanner app is correctly configured for your BMW 120D e82 and that you’ve granted it all necessary permissions.
To troubleshoot this, consider trying alternative OBD2 apps available for Android. Free apps like Torque Lite or OBD Auto Doctor offer similar functionalities and might be more effective in reading codes with your specific adapter. User reviews for similar ELM327 adapters often mention successful code reading, even for ABS faults, suggesting the hardware can work. Therefore, exploring different software options is a logical next step.
If alternative apps also fail to retrieve trouble codes, the issue might lie deeper. While less likely if live data is present, a fault with the specific communication protocol for code retrieval on your ELM327 adapter cannot be entirely ruled out. In such cases, consider testing the adapter on another vehicle if possible, or consulting online forums specific to your car model for user experiences with similar OBD2 tools. This can help determine if the problem is with the scanner, the app, or potentially a more complex issue with your car’s diagnostic system itself.
