PASSAT B8 Roof leak fixed FULL VIDEO part 2
In this video, I presents a comprehensive guide on addressing a water leakage issue in a vehicle's cabin, specifically focusing on the roof lining area. The first part of the video details the meticulous process of dismantling the roof lining to access the underlying components.
In the second part, I identifies the root cause of the water leak, which was traced back to the screws securing the roof supports. It is highlighted that Volkswagen made a design oversight by using standard nuts without safety washers, which are essential for preventing loosening over time due to constant vibrations during driving. This design flaw allows water to seep into the cabin, leading to significant damage over the years.
To rectify this issue, I replaced the standard nuts with nuts that include safety washers, ensuring a more secure fit. Additionally, a sealing compound was applied to the upper side as an extra waterproofing measure. The video serves as both an informative tutorial and a critique of the manufacturer's design choice, suggesting that Volkswagen should consider revising this aspect in future models to prevent similar issues.

Thank you.
How tight did you tighten the nuts?

I'm glad the video was helpful.
The nuts were so loose that they could be unscrewed by hand. I tightened them by feel, using a small ratchet.
