Opel Insignia Trunk and Roof Problems

For the trunk lid issue, start by checking the hydraulic struts or lift supports to ensure they are not worn out or leaking, as this could prevent the lid from lifting automatically. For the trunk position sensor error, inspect the wiring and connections to the sensor for any damage or loose connections. Regarding the sunroof, try resetting it by holding the sunroof switch in the closed position for about 10 seconds to recalibrate it. If these steps don't resolve the issues, it might be best to consult a professional mechanic. Let me know how it goes or if you have any further questions!
