The loud noise comes from the wheels of my Peugeot 806
As we have seen before, loud noise from the wheels of your Peugeot 806 may be linked to two main disorders. 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 consider 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 swap it or them straight 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 Peugeot 806 that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your technician to replace the tires or perform a balancing.

The loud noise comes from the engine of my Peugeot 806

In the first case, a turbo failure may also be linked to 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 Peugeot 806 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 problems, take your car to your garage .

To confirm this, get help from someone who will stand under the automobile while you accelerate to find the exact area of source of this noise.
