You can do a proper diagnostics run-through with the full version of the app.
This is how it works:
- Let the diagnostics run through
- Erase the found faults
- Drive a couple minutes with your car
- Let the diagnostics run through again
- Fault codes that are still found after this procedure mean that this fault is current in your car
You can find here how this knowledge can help you.
The other faults were saved once and could be erased.
