What is the reason for water leakage in the Audi TT trunk?

[OMason]

The reason for water leakage in the Audi TT trunk is the loose installation or detachment of the spoiler drain pipe. The causes of trunk water leakage include: Worn or aged trunk seals, trunk deformation, and clogged drain pipes. Trunk maintenance methods: When cleaning, use a brush to remove dirt, including the edges and grooves of the trunk, followed by odor treatment after cleaning; use organized storage bags to place items systematically; lay a trunk mat to prevent dirt or liquids from entering and corroding the trunk surface, while also preventing items from sliding inside the trunk, reducing the risk of contamination or damage.
