What Causes the Noise When Opening the Door After Turning Off the Engine?
1 Answers
After turning off the engine, the noise when opening the door mainly comes from the door hinges and limiters. Due to years of opening and closing, the door hinges and limiters experience wear and dust accumulation in the gaps, leading to vibration interference and abnormal noises during door operation. You can repeatedly apply engine oil with a cotton swab to the marked areas (red circles) of the door hinges and limiters, then repeatedly open and close the door. Repeat the steps of applying engine oil and operating the door until the noise disappears. The function of the door opening limiter is to restrict the degree to which the door can open. On one hand, it limits the maximum opening angle of the door to prevent it from opening too wide; on the other hand, it keeps the door open when needed, such as when the car is parked on a slope or during windy conditions, preventing the door from automatically closing.
