When it rains, water leaks inside on the right door pillar of my 2018 LDV D90 Luxe.
It’s often the case that the spot you see water entering the car is not where the actual leak is located. Water can take all sorts of interesting routes on the way to where you can see it, being driven by both the air passing over the car and following the odd shapes and profiles that make up the bits of a car’s body you can’t see.
But believe it or not, one of the best ways to find the source of a leak is to sit in the car while somebody on the outside trains a garden hose in specific places. As the aim of the hose moves, you might find the leak increases and decreases, helping you pin-point the source.
This cause of a water leak can sometimes be as simple as a small twig or leaf stuck in a door rubber, but it can also be the result of a damaged seal, body damage and even a replacement windscreen that has not been sealed properly.
