First, we will summarize the possible reasons for the trouble according to when loud noise shows up on your Audi Tt, and then we will concentrate on the region of origin of the noise. In any case, if this noise continues, follow these suggestions to help you find the origin.

When does my Audi Tt produce a loud noise?
One way to find a noise from your Audi Tt is to establish when it appears. Indeed, some trouble can be connected to components that are only stressed under certain types of conditions. It is this method that we will focus on in this first part.
Loud noise Audi Tt when accelerating
Loud noise on Audi Tt that starts when you are accelerating can be symptomatic of multiple 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 generate a much higher noise than during normal use. In addition, it is also highly plausible that loud noise on your Audi Tt is connected to a wheel bearing, which is one of the most common origins of these types of manifestations. 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 increases speed.

When my Audi Tt is stopped
If your Audi Tt makes a loud noise while not accelerating, engine on, the issue may be in connection with poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.
Where does loud noise come from on my Audi Tt and how can I be sure of its origin?
Now that we have identified the origin of the sound, we will deal with the verification step to ensure that this is the concern you are going through.

The loud noise comes from the wheels of my Audi Tt
As we have seen previously, loud noise from the wheels of your Audi Tt may be in connection with two main disorders. 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 replace it or them straight away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Audi Tt that is the issue, 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 auto technician to swap the tires or do a balancing.

The loud noise comes from the engine of my Audi Tt
In case you have identified loud noise as coming from the engine of your Audi Tt, 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 Tt 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 induce 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 disorders, take your car to your garage .

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