When does my Fiat 500 generate a loud noise?
One way to discover a noise from your Fiat 500 is to define when it appears. Indeed, some trouble can be connected to components that are only stressed under certain circumstances. It is this process that we will focus on in this first part.
Loud noise Fiat 500 when accelerating
Loud noise on Fiat 500 that happens when you are accelerating can be symptomatic of different failures. Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal use. Furthermore, it is also highly possible that loud noise on your Fiat 500 is in connection with a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Fiat 500 is stopped
If your Fiat 500 makes a loud noise while not accelerating, engine on, the problem may be linked 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 Fiat 500 and how can I be sure of its origin?
Now that we have defined the source of the noise, we will concentrate on the verification step to be certain that this is the matter you are encountering.

The loud noise comes from the wheels of my Fiat 500
As we have seen earlier in this article, loud noise from the wheels of your Fiat 500 may be linked to two main disorders. 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 bear in mind 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 replace 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 Fiat 500 that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Fiat 500
In case you have discovered loud noise as coming from the engine of your Fiat 500, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 Fiat 500 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 cause 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 trouble, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Fiat 500, it is highly possible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Fiat 500, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the car while you accelerate to find the exact area of starting point 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.
