When does my Nissan Micra 2 produce a loud noise?
One way to find a noise from your Nissan Micra 2 is to define when it occurs. Indeed, some problems can be related to components that are only stressed under certain conditions. It is this approach that we will focus on in this first part.
Loud noise Nissan Micra 2 when accelerating
Loud noise on Nissan Micra 2 that occurs when you are accelerating can be symptomatic of multiple failures. In fact, 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. Additionally, it is also highly plausible that loud noise on your Nissan Micra 2 is linked to a wheel bearing, which is one of the most common causes of these types of symptoms. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Nissan Micra 2 is stopped
If your Nissan Micra 2 makes a loud noise while not accelerating, engine on, the trouble may be in connection with poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.
Where does loud noise come from on my Nissan Micra 2 and how can I be sure of its origin?
Now that we have defined the cause of the sound, we will focus on the verification stage to be certain that this is the matter you are having.

The loud noise comes from the wheels of my Nissan Micra 2
As we have seen before, loud noise from the wheels of your Nissan Micra 2 may be in connection with 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 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 right 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 Nissan Micra 2 that is the matter, 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 replace the tires or do a balancing.

The loud noise comes from the engine of my Nissan Micra 2
In case you have recognized loud noise as coming from the engine of your Nissan Micra 2, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 Nissan Micra 2 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 verify that the engine idle speed is not random. In case you confirm one of these two trouble, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Nissan Micra 2, 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 Nissan Micra 2, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the car while you accelerate to find the exact area of starting point 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.
