When does my Audi A2 produce a loud noise?
One way to discover a noise from your Audi A2 is to define when it appears. Indeed, some concerns can be linked to components that are only stressed under certain types of conditions. It is this technique that we will focus on in this first part.
Loud noise Audi A2 when accelerating
Loud noise on Audi A2 that appears when you are accelerating can be symptomatic of multiple 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 use. Additionally, it is also highly plausible that loud noise on your Audi A2 is associated with a wheel bearing, which is one of the most common origins of these types of symptoms. 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 A2 is stopped

The loud noise comes from the wheels of my Audi A2
As we have seen earlier in this article, loud noise from the wheels of your Audi A2 may be related to two main problems. 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 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 change 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 A2 that is the matter, 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 change the tires or accomplish a balancing.

The loud noise comes from the engine of my Audi A2
In case you have discovered loud noise as coming from the engine of your Audi A2, 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 A2 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 verify 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 noticed comes from the exhaust pipe of your Audi A2, 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 A2, 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 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.
