The loud noise comes from the wheels of my Volkswagen Routan

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 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 replace it or them as soon as possible. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity.

If the loud noise on your Volkswagen Routan 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 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 vehicle to your garage .

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.
