What is the reason why the sunroof of the 2011 Tiguan cannot be closed when tilted up?

The issue of the Tiguan's sunroof not closing when tilted up is usually caused by foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance may prevent the sunroof from closing. First, check the sliding rails: When there is insufficient lubrication and excessive resistance, the sunroof's automatic anti-pinch feature will activate, resulting in the sunroof not closing. The primary maintenance for the sunroof involves lubricating the sliding rails. If lubrication is inadequate, over time, issues such as strange noises, poor movement, incomplete closure, or even jamming and misalignment may occur, potentially damaging the motor. Check the electrical circuit: Inspect whether the fuse for the electric sunroof has blown. If the fuse is intact, check if the sunroof switch is damaged. Press the switch to see if power is being supplied. If there is power, then check if the sunroof's drive motor is functioning. Listen carefully for any sounds indicating motor operation. Additionally, the sunroof not closing properly could be due to obstructions, deformation, rust, or poor lubrication in the sliding tracks.
