How to Solve the Buzzing Noise in Sagitar?

The car engine requires regular maintenance. When driving through particularly humid or dusty areas, it is necessary to inspect and maintain the engine. When engine oil passes through the fine holes of the oil filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged, the oil cannot pass through smoothly. Pollutants in the air can deposit around the PCV valve, potentially causing it to clog. It is essential to regularly maintain the PCV valve and remove pollutants around it.
I've been driving my Sagitar for five years and encountered humming noises several times, which are usually caused by unbalanced tires or faulty wheel bearings. First, check if the tires are worn or deformed. You can rotate the wheels yourself to listen for the source of the noise. If the noise increases with speed, it's likely a bearing issue. Don't underestimate it; severe bearing failure can lead to unstable wheels, which is very dangerous at high speeds. I recommend going to a professional repair shop for inspection—they can diagnose it quickly with tools. The cost depends on the situation; replacing a single bearing can cost a few hundred yuan, so don't opt for cheap roadside repairs. Regular maintenance, including wheel alignment, can help prevent this. Remember, safety comes first—don't delay, fix it early for peace of mind.
As a car enthusiast, I have some insights about the Jetta's humming noise. It mostly stems from tire or bearing issues - uneven tread wear or imbalance can cause humming, while bearing damage produces noticeably different sounds as speed increases. You can perform simple tests yourself: push the car in neutral to locate the noise source; check if brake pads show abnormal wear. Professional diagnosis is essential, using a multimeter for electrical checks or a lift to inspect the chassis. Improper modifications may also cause it, like installing larger rims without proper balancing. Cost-wise, new bearings cost around 500 yuan, while tire balancing only needs dozens. Never overlook minor issues as they may lead to major failures - timely repairs always pay off.
