When does my Audi Q3 generate a loud noise?
One way to discover a noise from your Audi Q3 is to determine when it appears. Indeed, some concerns can be related to parts that are only stressed under certain conditions. It is this approach that we will focus on in this first part.
Loud noise Audi Q3 when accelerating
Loud noise on Audi Q3 that takes place when you are accelerating can be symptomatic of multiple failures. In fact, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal process. Moreover, it is also highly plausible that loud noise on your Audi Q3 is connected to a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative 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 Q3 is stopped
If your Audi Q3 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 reason.

The loud noise comes from the wheels of my Audi Q3
As we have seen before, loud noise from the wheels of your Audi Q3 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 remember 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 change 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 Q3 that is the issue, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your auto mechanic to swap the tires or perform a balancing.

The loud noise comes from the engine of my Audi Q3
In case you have recognized loud noise as coming from the engine of your Audi Q3, 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 experience a power loss during your acceleration. If the loud noise on your Audi Q3 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 disorders, take your automobile to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Audi Q3, 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 Q3, 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 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.
