Particle filter test with Carly adapter for Opel Astra

You can use your Carly adapter to read the fault codes from your car's computer. These codes can give you an idea of what's causing the engine to run rough and why the check engine light is on. Here's how you can do it: 1. Plug the Carly adapter into the OBD2 port of your car. It's usually located under the dashboard. 2. Download and install the Carly app on your smartphone. 3. Connect your smartphone to the Carly adapter via Bluetooth. 4. Open the Carly app and select your car model. 5. Go to the 'Check Engine' section and start the diagnosis. The app will then read the fault codes and provide you with a detailed explanation of each one. If the particulate filter is the issue, it should show up in the fault codes. Please let me know what fault codes you get so I can help you further. Do you have any other questions?
