When does my Peugeot 307 produce a loud noise?
One way to find a noise from your Peugeot 307 is to determine when it appears. Indeed, some concerns can be linked to components that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise Peugeot 307 when accelerating
Loud noise on Peugeot 307 that appears when you are accelerating can be symptomatic of different failures. Indeed, if you experience 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 process. Furthermore, it is also highly plausible that loud noise on your Peugeot 307 is connected 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 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 307 is stopped
If your Peugeot 307 makes a loud noise while not accelerating, engine on, the problem may be connected to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.

The loud noise comes from the wheels of my Peugeot 307
As we have seen earlier in this article, loud noise from the wheels of your Peugeot 307 may be connected 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 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 replace it or them as soon as possible. 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 Peugeot 307 that is the issue, 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 auto technician to swap the tires or execute a balancing.

The loud noise comes from the engine of my Peugeot 307
In case you have discovered loud noise as coming from the engine of your Peugeot 307, the two most likely causes are turbo and air intake. 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 307 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 cause 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 automobile to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Peugeot 307, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Peugeot 307, 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 vehicle 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.
