Causes of Abnormal Noises While Driving a Golf 7

Causes of abnormal noises while driving a Golf 7 are as follows: 1. Cold start, abnormal noise from the engine compartment. This may be due to the belt slipping on the generator, where intense friction and vibration between the belt and pulley produce a sound at a certain frequency. The main reason for belt slipping is belt looseness or aging. Factors that may cause belt looseness include incorrect adjustment of the belt tensioner or insufficient elasticity of the tensioner. The tension of the belt tensioner must first be adjusted. If there is no effect, replace the tensioner. 2. Abnormal noise from the steering wheel. If an abnormal sound occurs after turning the steering wheel, first check whether the steering gear oil is normal or if the power steering fluid is too low, causing the power steering pump to fail to work properly (except for electric power steering), resulting in abnormal sounds when adjusting the direction.

When I first drove my Golf 7, I always heard a gurgling sound from the chassis on the road, which worried me a lot. Later, I found out that this could be a suspension issue, such as aging shock absorbers or loose bushings, especially noticeable when going over bumps. Tires could also be the culprit; if the tread is severely worn or small stones are stuck in them, they tend to squeak when turning. I also noticed that when the brake pads are nearly worn out, they make a squealing noise, especially noticeable during slow stops. Once, the noise got louder on a rainy day, and I found out it was caused by the loose plastic underbody guard rubbing against something. Remember, don't ignore these small sounds—safety first. I quickly went to the 4S dealership to have the suspension components checked, and now it's much quieter. I've developed a habit of listening to the sounds from the engine bay and tire area before driving every time.

Abnormal noises during driving in the Golf 7 are mostly caused by loose or worn mechanical components. For example, uneven tire aging can produce a low-frequency humming noise, especially noticeable at high speeds. Loose ball joints or control arms in the suspension system will create squeaking sounds, particularly prominent when going over speed bumps. I also thought of issues with the braking system—if the brake discs are corroded or the calipers don’t retract properly, it results in a harsh scraping sound. Additionally, insufficient lubrication in the driveshaft bearings may cause a rumbling noise. Don’t underestimate these minor issues, as they may indicate potential risks. It’s recommended to regularly check tire pressure and tread depth, and then listen to whether the noise originates from the front or rear of the car. For diagnosis, it’s best to use professional methods, such as a stethoscope tool to pinpoint the source, as misdiagnosis is easy otherwise.

When I hear abnormal noises while driving my Golf 7, I always pull over to check. The most common issue is excessive wind noise - aging door seals or an improperly closed sunroof can cause a whooshing sound. If there's a rattling noise from the chassis, it might be caused by foreign objects like stones stuck under the protective plate. A high-pitched whine at higher speeds could indicate a faulty wheel hub bearing or loose steering system screws. Pay special attention to brake issues - worn brake pads will squeak during deceleration. For safety, note down the frequency and timing of the sounds to help with diagnosis.
