Where are the drainage holes on the BMW 3 Series doors?
2 Answers
The drainage holes are located at the bottom of the door panel, usually with 1-2 holes. Below is an introduction to the BMW Mini: Brand: The BMW Mini is a British microcar brand, now under the BMW Group. Mini originally started as a specific model known as the "Morris Mini-Minor," introduced by the British Motor Corporation in 1959, and later developed into a brand with multiple small car models. Color Options: The BMW Mini offers a very rich selection of color combinations, allowing you to choose either the same color for the body and roof or different colors for the body and roof.
The drainage holes on the BMW 3 Series doors are actually quite easy to locate. Just crouch down and inspect the bottom edge of the door—you'll typically find a small hole or narrow slit near the lowest part of the door, close to the side. This design is quite clever, as it allows rainwater flowing down the door to drain out promptly, preventing water accumulation that could damage the wiring inside the door or cause rust. I once experienced a door leakage issue because these holes were clogged with mud and leaves. To clear them, simply use a thin wire to gently poke through the blockage—no need for a special trip to the repair shop. Developing a habit of regular inspections is crucial, especially before and after the rainy season. Unusual noises or a heavy feeling when opening the door might signal water accumulation, which should be addressed immediately.
