What Causes the BMW 5 Series Door to Make Noise When Exposed to Water?
1 Answers
Here are the specific reasons why the BMW 5 Series door makes noise when exposed to water: Worn Door Hinges: Use a cloth or tissue to wipe away surface dust, then apply a small amount of lubricating oil with a cotton swab to the door hinges and the marked areas of the door limiter. Open and close the door repeatedly, reapplying the oil and repeating the process until the noise disappears. Avoid applying too much lubricating oil to prevent contamination of other door parts. If the noise persists, it may be due to wear and tear, requiring replacement of new hinges and limiters. Aging Door Seals: Check if the door seals are aging. The seals are made of rubber, so regularly clean the dust and rainwater between the seal gaps to prevent aging. Since sand and dust can easily accumulate in the gaps of the seals, use a brush to frequently clean them, then apply a layer of highly permeable protective agent to prevent the seals from aging. If the seals are severely damaged or significantly aged, they need to be replaced with new ones.
