What to Do When the Passat Sunroof Opens Automatically?

[StAdam]

If the Passat sunroof opens automatically, check the sunroof sliding rails. If there are foreign objects or insufficient lubrication on the rails, excessive resistance may trigger the automatic anti-pinch feature, preventing it from closing. This is not a malfunction; simply lubricating the rails once should resolve the issue. Below are some precautions for using the Passat sunroof: 1. Before opening the sunroof, ensure there are no obstacles on the roof that could hinder its sliding. 2. Avoid using the sunroof on bumpy roads to prevent damage to the sunroof and rail components caused by vibrations. 3. Do not open the sunroof during rainy weather or when washing the vehicle to prevent rain or water droplets from aging and rusting the rubber seals and metal parts. If you wish to open the sunroof after rain, make sure to dry the water droplets on the roof first.
