Additionally, the OPL DRC Reader can retrieve mileage data from certain modules, which can be particularly useful for tracking vehicle usage.

Important Note: For optimal performance, the app requires a compatible ELM327 Bluetooth interface, with a minimum version of 1.3. It's crucial to use a high-quality ELM327 device, as low-quality clones may not work properly. You can verify the compatibility of your ELM327 interface using the ELM Identifier application available on Google Play: ELM Identifier.

Works fine for quick DTC checks on my 2015 Opel. Not the most advanced tool but gets the job done for basic diagnostics. 👍
