When does my Renault Master make a loud noise?
One way to discern a noise from your Renault Master is to establish when it appears. Indeed, some problems can be linked to parts that are only stressed under certain circumstances. It is this process that we will focus on in this first part.
Loud noise Renault Master when accelerating
Loud noise on Renault Master that appears when you are accelerating can be symptomatic of several failures. Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal use. In addition, it is also highly plausible that loud noise on your Renault Master is linked to a wheel bearing, which is one of the most common origins 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 trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Renault Master is stopped
If your Renault Master makes a loud noise while not accelerating, engine on, the trouble 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 Master and how can I be sure of its origin?
Now that we have located the source of the noise, we will deal with the verification step to ensure that this is the issues you are experiencing.

The loud noise comes from the wheels of my Renault Master
As we have seen earlier in this article, loud noise from the wheels of your Renault Master may be in connection with 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 keep in mind 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 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 Master that is the issue, 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 auto technician to change the tires or execute a balancing.

The loud noise comes from the engine of my Renault Master
In case you have identified loud noise as coming from the engine of your Renault Master, 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 encounter a power loss during your acceleration. If the loud noise on your Renault Master 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 induce 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 disorders, 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 Renault Master, it is highly plausible 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 Renault Master, 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 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.
