When does my Audi A5 generate a loud noise?
One way to discern a noise from your Audi A5 is to identify when it appears. Indeed, some concerns can be linked to parts that are only stressed under certain types of conditions. It is this technique that we will focus on in this first part.
Loud noise Audi A5 when accelerating
Loud noise on Audi A5 that shows up when you are accelerating can be symptomatic of different failures. In fact, if you experience 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. Furthermore, it is also highly plausible that loud noise on your Audi A5 is in connection with a wheel bearing, which is one of the most common causes 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 gains speed.

When my Audi A5 is stopped
If your Audi A5 makes a loud noise while not accelerating, engine on, the issue may be linked 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 A5 and how can I be sure of its origin?
Now that we have located the source of the sound, we will concentrate on the verification step to ensure that this is the issues you are going through.

The loud noise comes from the wheels of my Audi A5
As we have seen earlier in this article, loud noise from the wheels of your Audi A5 may be linked to 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 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 change it or them straight away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Audi A5 that is the matter, 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 auto mechanic to swap the tires or do a balancing.

The loud noise comes from the engine of my Audi A5
In case you have discovered loud noise as coming from the engine of your Audi A5, 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 A5 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 cause 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 trouble, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Audi A5, 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 Audi A5, 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 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.
