How to Deal with Clogged Drain Holes in BMW 3 Series?
1 Answers
Simply use a soft steel wire to unclog it. Below is an introduction to car drain holes: 1. Air conditioning drain hole: If the air conditioning drain hole is clogged, pay attention to the floor. If it gets wet, check if the air conditioning drain hole is blocked. 2. Engine compartment drain hole: The engine compartment drain hole is prone to clogging, which can cause engine failure and affect the engine computer in some car models. 3. Sunroof drain hole: Since the sunroof drain hole is located at the top, it is easily clogged by leaves and dirt, requiring regular inspection and maintenance. 4. Fuel tank cap drain hole: While driving, some debris can accumulate in the fuel tank cap's crevices. In rainy or humid conditions, this can lead to water accumulation, corroding the fuel tank cap and door panels, so regular checks are necessary. 5. Door drain hole: Due to its low position, the door drain hole can be affected when driving on muddy or waterlogged roads. If water accumulates inside the door, it can damage the window regulator and audio equipment. 6. Trunk drain hole: The trunk drain hole rarely gets waterlogged, but if water enters the trunk on waterlogged roads or due to spills, it should be drained as soon as possible, often requiring manual opening of the trunk drain hole.
