Water leakage in the left A-pillar of the 4008 sunroof is due to poor sealing of the front windshield or blockage of the sunroof drainage system. Below are the specific details of the Peugeot 4008: 1. Vehicle Positioning: The Dongfeng Peugeot 4008 is a strategic SUV model under Dongfeng Peugeot, with dimensions of 4510/1850/1662mm in length, width, and height, and a wheelbase of 2730mm. 2. Powertrain: It is equipped with a 2.0L engine (model 4B11) with a maximum output of 150 horsepower and a peak torque of 198Nm, paired with either a CVT or manual transmission, offering front-wheel or four-wheel drive options.
I've been driving this car for several years and encountered a situation where water leaked from the sunroof to the left A-pillar, usually due to issues with the drainage system. The sunroof has four drainage pipes, and the left one is likely clogged or broken. Leaves, dirt, and other debris accumulate at the drainage holes, preventing water from draining properly, which then flows internally to the A-pillar. Aging of the sealing strips can also cause gaps that let water in. When I dealt with this before, I first tried clearing the drainage holes with a soft pipe. If it still leaks, you need to check if the pipe is cracked or the joints are loose. These small issues are quite common as the car ages, and regular cleaning of the sunroof tracks can prevent them. If left unrepaired for a long time, it can lead to moldy interiors or even affect electrical safety. I recommend a simple monthly cleaning of the drainage holes to avoid embarrassing leaks during heavy rain.
As an average car owner, I find it quite frustrating when the sunroof leaks into the left A-pillar, which is mostly caused by clogged drainage tubes or damaged seals. After driving my Peugeot 4008 for three years, I suddenly noticed water dripping from the A-pillar during the recent rainy season. Upon removing the interior trim panel, I found the drainage holes completely blocked by debris. I tried clearing them with compressed air, and the issue was immediately resolved. If the tubes are aged and cracked, they'll need replacement. Additionally, sunroof seals can shrink and deform over time, allowing water to seep in unnoticed. This problem shouldn't be delayed, as it can lead to frame corrosion or electrical shorts. I make it a habit to clean the sunroof gaps during every car wash—it's both convenient and ensures safety.
