What causes abnormal noises when a Volkswagen Polo is running?
2 Answers
The reasons for abnormal noises when a Volkswagen Polo is running are as follows: Oil issue: The engine oil does not fully lubricate all components of the engine. After running for a while, the new oil can evenly lubricate all parts of the engine. If the problem persists after some time, it may be due to severe wear. Cleaning the internal parts of the engine can reduce the abnormal noise. Poor sealing: Large gaps and poor sealing can lead to deteriorating engine conditions, which may also cause abnormal noises. It is recommended to visit a repair shop for inspection. Maintenance issue: If maintenance is neglected, excessive carbon buildup in the machine (such as excessive carbon in the engine, throttle, spark plugs, etc.) may be the cause. A visit to a repair shop for cleaning should resolve the issue.
I've been driving a Volkswagen Polo for several years, and the strange noises while driving are quite annoying. The most common issue is uneven tire pressure causing rubber friction sounds, or loose suspension components like worn shock absorbers making creaking noises. Another possibility is uneven brake discs or loose brake pads, which produce clunking sounds when braking. Body parts such as aging door seals or loose seat buckles can also squeak, especially noticeable when going over speed bumps. I've also experienced the hood not being closed tightly, resulting in a whooshing wind noise. For self-inspection, first, park and check if the tire pressure is normal, then listen to the source of the noise. Front wheel noises are often due to bearing issues, while rear noises might indicate a loose exhaust. Don't ignore strange noises while driving; get them checked at a professional shop promptly to avoid minor issues leading to major accidents. Safety comes first.
