What are the reasons for the loud noise in Volkswagen engines?
2 Answers
Volkswagen engine noise is loud due to the following reasons: 1. The engine oil and oil filter have not been replaced regularly; 2. The engine mounts have become loose or damaged; 3. There is an issue with the engine's intake tract or air filter that requires inspection. If the vehicle exhibits loud noises, it is essential to conduct an inspection promptly to prevent major issues that could render the vehicle inoperable. Taking the 2021 Volkswagen Polo Plus 1.5L Manual Panorama Enjoyment Edition as an example: it is a compact 5-door, 5-seat hatchback with dimensions of 4053mm in length, 1740mm in width, and 1449mm in height, a wheelbase of 2564mm, and a top speed of 190 kilometers per hour.
When driving my Volkswagen, I encountered loud engine noise, which felt quite annoying with a buzzing sound. It's probably because the engine is old or the belt is loose. After prolonged use of a Volkswagen, wear on piston rings or chains can increase noise, as if the cylinder gap has widened or the oil passage is blocked. Checking the engine oil is essential; when I used regular oil, the noise was louder, but it improved significantly after switching to full synthetic oil. If left unaddressed, it might lead to a breakdown on the road. Last time, the repair cost me several hundred dollars, so I recommend servicing every five thousand kilometers to avoid bigger troubles later.
