When does my Peugeot 207 generate a loud noise?

Loud noise Peugeot 207 when accelerating
Loud noise on Peugeot 207 that happens when you are accelerating can be symptomatic of multiple failures. In fact, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Peugeot 207 is linked to a wheel bearing, which is one of the most common causes 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.

The loud noise comes from the wheels of my Peugeot 207
As we have seen earlier in this article, loud noise from the wheels of your Peugeot 207 may be connected 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 keep in mind to examine 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 change it or them straight away. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Peugeot 207 that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your technician to change the tires or perform a balancing.

The loud noise comes from the engine of my Peugeot 207
In case you have discovered loud noise as coming from the engine of your Peugeot 207, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with 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 207 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 cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Peugeot 207, 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 207, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify 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.
