When does my Toyota Avensis generate a loud noise?
One way to discern a noise from your Toyota Avensis is to establish when it appears. Indeed, some problems can be related to parts that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise Toyota Avensis when accelerating
Loud noise on Toyota Avensis that takes place when you are accelerating can be symptomatic of multiple failures. Indeed, if you feel 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 use. Additionally, it is also highly possible that loud noise on your Toyota Avensis is linked to 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 possible that the problem 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 Avensis
As we have seen before, loud noise from the wheels of your Toyota Avensis may be linked 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 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 change it or them quickly. 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 Toyota Avensis that is the trouble, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to swap the tires or perform a balancing.

The loud noise comes from the engine of my Toyota Avensis
In case you have identified loud noise as coming from the engine of your Toyota Avensis, 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 experience a power loss during your acceleration. If the loud noise on your Toyota Avensis 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 detected comes from the exhaust pipe of your Toyota Avensis, 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 Toyota Avensis, 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 origin 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.
