VW Tiguan 2014 Part 2 | Sunroof Leak Video
Upon testing the sunroof, it was found there was no rear drainage, almost certainly because the drainage pipes are blocked with dirt and debris, causing the cassette to fill up.
What can happen is although some of the water can drain away using the front pipes, water is left sitting in the cassette, which is a tray the sunroof mechanism sits in. And then when you drive away, the water slops over the edge of the tray.
We recommend unblocking the pipes and flushing them through. This should fix the problem because in a car of this age, it is unlikely they have shrunk or perished.
Water in the car has caused a damp smell which indicates mould, so the car will need to be decontaminated, and an odour treatment applied, as well as drying the car.
We have been repairing leaks and drying cars for over 30 years
Up to a third of the cost of your car was computers, processors and sensors. Delicate electrical systems hidden under your carpets, which might now be sitting in water.
