When does my Audi Q7 make a loud noise?
One way to discover a noise from your Audi Q7 is to determine when it occurs. Indeed, some concerns can be connected 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 Q7 when accelerating
Loud noise on Audi Q7 that starts when you are accelerating can be symptomatic of different failures. Indeed, if you experience 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 use. Moreover, it is also highly plausible that loud noise on your Audi Q7 is related to a wheel bearing, which is one of the most common causes of these types of symptoms. 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 Audi Q7 is stopped
If your Audi Q7 makes a loud noise while not accelerating, engine on, the trouble 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.

The loud noise comes from the wheels of my Audi Q7
As we have seen previously, loud noise from the wheels of your Audi Q7 may be linked 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 remember 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 Q7 that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your mechanic to replace the tires or execute a balancing.

The loud noise comes from the engine of my Audi Q7
In case you have discovered loud noise as coming from the engine of your Audi Q7, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be linked 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 Audi Q7 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 verify that the engine idle speed is not random. In case you confirm one of these two disorders, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Audi Q7, 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 Q7, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle 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.
