When does my Renault Vel Satis make a loud noise?
One way to identify a noise from your Renault Vel Satis is to determine when it appears. Indeed, some concerns can be related to components that are only stressed under certain occasions. It is this approach that we will focus on in this first part.
Loud noise Renault Vel Satis when accelerating
Loud noise on Renault Vel Satis that appears when you are accelerating can be symptomatic of multiple failures. Indeed, if you encounter 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 process. Furthermore, it is also highly plausible that loud noise on your Renault Vel Satis is associated 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 issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Renault Vel Satis is stopped
If your Renault Vel Satis 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 induce.

The loud noise comes from the wheels of my Renault Vel Satis
As we have seen previously, loud noise from the wheels of your Renault Vel Satis 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 keep in mind to verify 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 swap it or them quickly. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Renault Vel Satis that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your mechanic to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Renault Vel Satis
In case you have recognized loud noise as coming from the engine of your Renault Vel Satis, 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 Vel Satis 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 verify 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 detected comes from the exhaust pipe of your Renault Vel Satis, 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 Vel Satis, 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.
