When does my Audi S5 generate a loud noise?
One way to discern a noise from your Audi S5 is to define when it shows up. 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 Audi S5 when accelerating
Loud noise on Audi S5 that starts 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 generate a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Audi S5 is linked to 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 trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Audi S5 is stopped
If your Audi S5 makes a loud noise while not accelerating, engine on, the trouble 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.
Where does loud noise come from on my Audi S5 and how can I be sure of its origin?

The loud noise comes from the wheels of my Audi S5
As we have seen earlier in this article, loud noise from the wheels of your Audi S5 may be related to two main trouble. 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 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 swap 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 Audi S5 that is the matter, 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 swap the tires or perform a balancing.

The loud noise comes from the engine of my Audi S5
In case you have identified loud noise as coming from the engine of your Audi S5, 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 Audi S5 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 generate 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 noticed comes from the exhaust pipe of your Audi S5, it is highly plausible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Audi S5, 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 automobile 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.
