When does my Audi E-Tron generate a loud noise?
One way to detect a noise from your Audi E-Tron is to define when it appears. Indeed, some problems can be related to components that are only stressed under certain types of conditions. It is this process that we will focus on in this first part.
Loud noise Audi E-Tron when accelerating
Loud noise on Audi E-Tron that takes place when you are accelerating can be symptomatic of several failures. Indeed, if you encounter 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. Furthermore, it is also highly possible that loud noise on your Audi E-Tron is related to a wheel bearing, which is one of the most common origins 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 possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my Audi E-Tron
As we have seen earlier in this article, loud noise from the wheels of your Audi E-Tron may be in connection with 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 bear in mind 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 right away. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Audi E-Tron that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both cases, you will have to go to your auto mechanic to change the tires or execute a balancing.

The loud noise comes from the engine of my Audi E-Tron
In case you have identified loud noise as coming from the engine of your Audi E-Tron, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 E-Tron 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 verify that the engine idle speed is not random. In case you confirm one of these two problems, take your automobile 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 E-Tron, it is highly possible 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 E-Tron, 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 car 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.
