💧 This car is a very good example of what happens with sunroofs on many makes and models of cars. In fact, both the leaks on this Jetta are generic problems which happen to practically call cars because all cars are assembled in much the same way.
Around the sunroof is a trough, where water can collect (this is often called the cassette for some reason), from here there are usually two or four drainage holes with silicone pipes which lead down to the front wheel arches. It is seldom the case that these silicone pipes are in one piece, and often they have a connector. Over time, the silicone pipes shrink and shorten, so they can pull off the connectors, or they can just work their way loose. It is sometimes the case that the connectors are made of plastic which perishes, becomes brittle and shatters, so there are a number of things that can go wrong back there in addition to just blocked pipes.
There are generally two things that can go wrong with the rear air vents, they can get dirty and grit and debris can stop then closing properly, or perhaps more common, the plastic and silicone seals become old, shrink or not as supple. These vents are a bit like a one way cat flap, they are a valve with a gate(s) that let air out, but not water in. Usually just a plastic hinge, time can take its toll on them, which is why its often best just to replace them.
