Why is the Volkswagen engine so loud

Because it is a direct injection oil supply system in the cylinder, it is loud.

Many car owners complain that the noise of their cars is getting louder and louder, what is the reason?

There are several main causes of high engine noise:

1.The oil of the vehicle is too viscous, which can easily lead to problems in engine operation, and the lubricating oil becomes poor, resulting in high engine noise.

2.Sometimes the belt is loose, which can cause the engine compartment to become louder.

3.The engine is noisy, and it is also possible that the water temperature is too high, so you should see if the water temperature gauge is normal.

4.If you feel that the noise is relatively loud when idling, and the idle speed of the vehicle is high, it is likely that your car's throttle, air intake, and fuel injector should be cleaned.

5.Listening to the engine running normally when you are outside, but feeling that the noise is too loud when you sit in the car, it means that your vehicle is poorly insulated.

6.When the car is driving at high speed, the car body itself produces resonant sound, and high-efficiency sound-absorbing cotton is installed for noise reduction treatment.

7.Due to the thin metal and plastic plates of medium and low-end vehicles, the external noise is introduced, and the sound insulation thickened plates are installed to block the noise.

8.Adding shock absorbers and sound-insulating foam to the door trim can reduce the resonance of the door sheet metal structure when driving.

When the car starts cold, it has not yet formed a sufficient oil film, so the sound will be relatively loud, and the quality of the added engine oil will be ruined

In fact, there are a lot of noise in the car caused by the driver's psychological problems, not that the noise is small, but the noise is infinitely amplified under the driver's psychological cues. If you say that the EA888, EA113, and EA111 engines are loud, it may be really loud. The A8 you're talking about is also loud, then it's a bit of a problem, unless the car is an accident car and the sound insulation and firewall are not done well.

Try to put a soft ** when driving, and don't let the noise affect your mood when driving. I wish you a safe journey.

Also, my Magotan oil consumption is 1w km 1l, and our riders will have hundreds of cars, most of which are burned, and there is no way.

Hello landlord, do you want to see if the sound is so loud when you first buy it, what is the sound like when you are in the new car?
