The car needs to be powered on. Please try it again. If it still does not work after 2-3 tries send the debug data it asks you to send at the end when it fails and let me know the time so i can check which command fails.
Hi Samuel, many thanks for you reply. I need to have a premium subscription for this feature works?
No premium required. You need to add a car though, not just select it from the quick selection. Once added you can click on the car settings and link the OBD dongle.
