When does my Citroen C15 make a loud noise?
One way to discern a noise from your Citroen C15 is to establish when it appears. Indeed, some problems can be related to components that are only stressed under certain circumstances. It is this method that we will focus on in this first part.
Loud noise Citroen C15 when accelerating
Loud noise on Citroen C15 that takes place 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 provoke a much higher noise than during normal process. In addition, it is also highly plausible that loud noise on your Citroen C15 is associated with a wheel bearing, which is one of the most common origins of these types of manifestations. Another possibility 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 increases speed.

When my Citroen C15 is stopped

The loud noise comes from the wheels of my Citroen C15
As we have seen earlier in this article, loud noise from the wheels of your Citroen C15 may be linked 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 swap it or them quickly. 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 Citroen C15 that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both cases, you will have to go to your technician to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Citroen C15
In case you have discovered loud noise as coming from the engine of your Citroen C15, 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 Citroen C15 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 verify that the engine idle speed is not random. In case you confirm one of these two disorders, take your car 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 Citroen C15, 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 Citroen C15, 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 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.
