The loud noise comes from the wheels of my Audi A7
As we have seen earlier in this article, loud noise from the wheels of your Audi A7 may be linked to 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 bear in mind 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 right 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 A7 that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both cases, you will have to go to your auto technician to swap the tires or execute a balancing.

The loud noise comes from the engine of my Audi A7
In case you have identified loud noise as coming from the engine of your Audi A7, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated 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 A7 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 examine that the engine idle speed is not random. In case you confirm one of these two trouble, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Audi A7, 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 A7, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify 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.
