What causes the uneven height and inability to close the sunroof on the Tiguan?
2 Answers
Here are the specific reasons why the Tiguan's sunroof is uneven in height and cannot be closed: Aging and deformation of the sealing strip: The aging and deformation of the glass sealing strip causes resistance during the lifting of the glass, requiring timely replacement of a new sealing strip. If the aging is not severe, lubricant can be used for lubrication. Presence of foreign objects in the guide rail: Foreign objects, such as business cards or other debris inserted into the window when the vehicle is parked, may be present in the glass lifting guide rail, necessitating cleaning or removal of these objects. Malfunction of the lift mechanism: Symptoms of a faulty manual glass lift mechanism include slow lifting speed, weak motor performance, and glass tilting or coming off track.
I encountered the same sunroof issue with my Tiguan two months ago – one side was higher than the other and it just wouldn't close properly, which was incredibly frustrating. At first, I thought the motor was broken, but later discovered it was actually debris like dust or leaves stuck in the sunroof tracks, causing uneven sliding of the sliders. The anti-pinch function detected abnormal resistance and automatically stopped it from closing completely. I recommend first cleaning the track gaps with a soft cloth and spraying some sunroof-specific lubricant (avoid oily substances as they attract dust). Try gently pushing it manually to see if it resets, but be careful not to force it too hard and damage the motor. If that doesn’t work, it might be due to deformed guide rails or faulty sensors – in my case, I ended up going to the 4S shop to replace a slider before it was fixed. Regular maintenance is crucial; lubricating the tracks every six months can prevent such issues. Also, avoid opening the sunroof during rainy days to prevent water leakage problems.
