It is never pleasant to perceive a sound in your vehicle that you don’t know the starting point of. So, what if you discover a loud noise that is persistant on your Renault Trafic? It is extremely plausible that this is a minor problem, but before beeing sure, it is better to complete some inspections. Whether that loud noise comes from the front of the vehicle, from the rear, whether it happens when you accelerate or when you are parked, our team has written this content to help you fix it. First, we will describe the possible reasons for the issue according to when loud noise shows up on your Renault Trafic, and then we will concentrate on the region of origin of the noise. In any case, if this noise persists, follow these recommendations to help you find the source.

When does my Renault Trafic generate a loud noise?
One way to discern a noise from your Renault Trafic is to determine when it appears. Indeed, some trouble can be linked to components that are only stressed under certain conditions. It is this approach that we will focus on in this first part.
Loud noise Renault Trafic when accelerating
Loud noise on Renault Trafic that takes place when you are accelerating can be symptomatic of different failures. Indeed, if you experience 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. Moreover, it is also highly plausible that loud noise on your Renault Trafic is in connection with a wheel bearing, which is one of the most common origins of these types of signs of illness. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Renault Trafic is stopped
If your Renault Trafic makes a loud noise while not accelerating, engine on, the problem 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 cause.
Where does loud noise come from on my Renault Trafic and how can I be sure of its origin?
Now that we have defined the origin of the noise, we will concentrate on the verification stage to be certain that this is the matter you are enduring.

The loud noise comes from the wheels of my Renault Trafic
As we have seen earlier in this article, loud noise from the wheels of your Renault Trafic 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 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 Renault Trafic that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your auto mechanic to change the tires or execute a balancing.

The loud noise comes from the engine of my Renault Trafic
In case you have recognized loud noise as coming from the engine of your Renault Trafic, 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 Renault Trafic 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 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 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 Renault Trafic, 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 Renault Trafic, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of source 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.
