When does my Volkswagen Fox make a loud noise?
One way to discern a noise from your Volkswagen Fox is to define when it occurs. Indeed, some trouble can be connected to components that are only stressed under certain occasions. It is this process that we will focus on in this first part.
Loud noise Volkswagen Fox when accelerating
Loud noise on Volkswagen Fox that appears when you are accelerating can be symptomatic of several failures. In fact, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will induce a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Volkswagen Fox is linked to a wheel bearing, which is one of the most common causes of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Volkswagen Fox is stopped
If your Volkswagen Fox makes a loud noise while not accelerating, engine on, the issue may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.
Where does loud noise come from on my Volkswagen Fox and how can I be sure of its origin?
Now that we have uncovered the source of the noise, we will focus on the verification stage to be sure that this is the issues you are going through.

The loud noise comes from the wheels of my Volkswagen Fox
As we have seen previously, loud noise from the wheels of your Volkswagen Fox may be related to two main complications. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So remember to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case change it or them as soon as possible. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Volkswagen Fox that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your mechanic to replace the tires or execute a balancing.

The loud noise comes from the engine of my Volkswagen Fox
In case you have recognized loud noise as coming from the engine of your Volkswagen Fox, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your Volkswagen Fox is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would induce an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two problems, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Volkswagen Fox, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Volkswagen Fox, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of origin of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
