When does my Peugeot 807 produce a loud noise?
One way to discern a noise from your Peugeot 807 is to determine when it occurs. Indeed, some concerns can be connected to components that are only stressed under certain conditions. It is this technique that we will focus on in this first part.
Loud noise Peugeot 807 when accelerating
Loud noise on Peugeot 807 that occurs when you are accelerating can be symptomatic of several failures. Indeed, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will generate a much higher noise than during normal operation. In addition, it is also highly plausible that loud noise on your Peugeot 807 is in connection with 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 plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Peugeot 807 is stopped
If your Peugeot 807 makes a loud noise while not accelerating, engine on, the problem may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.

Now that we have located the cause of the noise, we will concentrate on the verification stage to make certain that this is the matter you are experiencing.

The loud noise comes from the wheels of my Peugeot 807
As we have seen previously, loud noise from the wheels of your Peugeot 807 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 keep 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 replace 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 Peugeot 807 that is the trouble, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your auto technician to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Peugeot 807
In case you have discovered loud noise as coming from the engine of your Peugeot 807, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 807 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 automobile to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Peugeot 807, it is highly plausible 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 Peugeot 807, 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 source 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.
