How to Fix Water Leakage in Golf Sunroof?

[Axel]

Remove the headliner of the Golf and observe the water stains. Check if the surrounding sealing strips are damaged; if they are, they need to be replaced. Regularly inspect the condition of the sunroof drainage pipes to ensure they are functioning properly without bends or blockages. Also, check the rubber seals and grooves of the sunroof for dust or debris. Inspect whether the drainage outlets are clogged with dust, as most sunroof leakages are caused by blocked drainage outlets.
