What Causes the Noise in BMW X1's Power Tailgate?

[DelEmmanuel]

BMW X1's power tailgate noise may be caused by the following reasons: Wear of Power Tailgate Hinges: Use a cloth or tissue to wipe off dust, then apply a small amount of lubricating oil with a cotton swab to the door hinges and the circled area of the limiter. Open and close the door repeatedly, and continue applying oil and repeating the door opening and closing steps until the noise disappears. Avoid applying too much lubricating oil to prevent contamination of other door parts. If the issue persists, it may be due to wear, and new hinges and limiters may need to be replaced. Aging of Power Tailgate Sealing Strips: Check if the door sealing strips are aging. As sealing strips are rubber products, regularly clean dust and rainwater from the gaps between the strips to prevent aging. Since sand and dust can easily accumulate in the gaps of the sealing strips, use a brush to frequently clean them, then apply a layer of highly permeable protective agent to prevent aging. If the sealing strips are severely damaged or significantly aged, they need to be replaced with new ones.
