Indeed, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal operation. In addition, it is also highly possible that loud noise on your Volkswagen Tiguan is linked to a wheel bearing, which is one of the most common causes of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the issue 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 Volkswagen Tiguan
As we have seen before, loud noise from the wheels of your Volkswagen Tiguan 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 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 Volkswagen Tiguan that is the trouble, 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 mechanic to change the tires or do a balancing.

The loud noise comes from the engine of my Volkswagen Tiguan
In case you have recognized loud noise as coming from the engine of your Volkswagen Tiguan, 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 Volkswagen Tiguan 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 check that the engine idle speed is not random. In case you confirm one of these two problems, take your automobile to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Volkswagen Tiguan, 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 Volkswagen Tiguan, 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.
