Whether that loud noise comes from the front of the vehicle, from the rear, whether it appears when you accelerate or when you are parked, our team has written this content to help you fix it. First, we will summarize the possible explanations for the trouble according to when loud noise appears on your Fiat 500 L, and then we will concentrate on the region of origin of the noise.

When does my Fiat 500 L make a loud noise?
One way to find a noise from your Fiat 500 L is to identify when it occurs. Indeed, some complications can be related to components that are only stressed under certain conditions. It is this process that we will focus on in this first part.
Loud noise Fiat 500 L when accelerating
Loud noise on Fiat 500 L that appears when you are accelerating can be symptomatic of several failures. In fact, if you encounter 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 process. Furthermore, it is also highly plausible that loud noise on your Fiat 500 L is associated with a wheel bearing, which is one of the most common causes of these types of manifestations. Another possibility 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 increases speed.

When my Fiat 500 L is stopped
If your Fiat 500 L makes a loud noise while not accelerating, engine on, the issue may be in connection with poor air intake. An air intake hose that has come loose or has a hole in it may be the induce.
Where does loud noise come from on my Fiat 500 L and how can I be sure of its origin?
Now that we have defined the source of the sound, we will deal with the verification stage to make sure that this is the concern you are enduring.

The loud noise comes from the wheels of my Fiat 500 L
As we have seen before, loud noise from the wheels of your Fiat 500 L may be in connection with two main problems. 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 consider to check 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 quickly. 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 L that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both cases, you will have to go to your mechanic to change the tires or execute a balancing.

The loud noise comes from the engine of my Fiat 500 L
In case you have identified loud noise as coming from the engine of your Fiat 500 L, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected to 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 L is related to air intake, the check 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 generate an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check 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 found comes from the exhaust pipe of your Fiat 500 L, 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 Fiat 500 L, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify 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.
