Where are the drainage holes located on the Passat?

[McEliana]

The Passat has multiple drainage holes distributed across various parts of the vehicle. Door drainage holes: These are located at the bottom of the doors. If water accumulates inside the door and you hear sloshing sounds when opening it, this typically indicates the door's drainage holes are clogged. Fuel filler flap drainage hole: Most vehicles have a drainage hole beneath the fuel filler flap. If this becomes blocked, water from car washes or rain cannot drain properly, potentially leading to water accumulation in the fuel tank area and causing damage. Sunroof drainage holes: The sunroof has drainage holes in all four corners. Even when closed during rain, water can enter and flows through guide channels to drainage holes A-C, eventually exiting beneath the vehicle.
