Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal process. In addition, it is also highly possible that loud noise on your Toyota Aygo 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 possible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

The loud noise comes from the wheels of my Toyota Aygo
As we have seen earlier in this article, loud noise from the wheels of your Toyota Aygo 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 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 swap it or them right away. 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 Toyota Aygo that is the problem, 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 mechanic to swap the tires or do a balancing.

The loud noise comes from the engine of my Toyota Aygo
In case you have identified loud noise as coming from the engine of your Toyota Aygo, 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 Toyota Aygo 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 generate 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 trouble, take your vehicle 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 Toyota Aygo, it is highly possible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Toyota Aygo, 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 automobile 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.
