When does my Audi Q5 make a loud noise?
One way to detect a noise from your Audi Q5 is to identify when it appears. Indeed, some complications can be related to components that are only stressed under certain conditions. It is this process that we will focus on in this first part.
Loud noise Audi Q5 when accelerating
Loud noise on Audi Q5 that takes place when you are accelerating can be symptomatic of multiple failures. Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal process. Moreover, it is also highly plausible that loud noise on your Audi Q5 is in connection with a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative 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 Audi Q5 is stopped
If your Audi Q5 makes a loud noise while not accelerating, engine on, the trouble may be connected to 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 Audi Q5 and how can I be sure of its origin?
Now that we have found the cause of the sound, we will focus on the verification step to make sure that this is the concern you are encountering.

The loud noise comes from the wheels of my Audi Q5
As we have seen previously, loud noise from the wheels of your Audi Q5 may be connected 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 consider 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, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Audi Q5 that is the problem, 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 do a balancing.

The loud noise comes from the engine of my Audi Q5
In case you have identified loud noise as coming from the engine of your Audi Q5, 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 encounter a power loss during your acceleration. If the loud noise on your Audi Q5 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 verify that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Audi Q5, 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 Audi Q5, 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 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.
