It is never pleasant to hear a sound in your vehicle that you don’t know the cause of. So, what if you find a loud noise that persists on your Nissan Micra 4? It is very plausible that this is a minor problem, but before beeing sure, it is better to operate some verifications. Whether that loud noise comes from the front of the vehicle, from the rear, whether it shows up when you accelerate or when you are parked, our team has written this article to help you solve it. First, we will summarize the possible reasons for the problem according to when loud noise appears on your Nissan Micra 4, and then we will look into the region of origin of the noise. In any case, if this noise remains, follow these advice to help you find the origin.

When does my Nissan Micra 4 generate a loud noise?
One way to discover a noise from your Nissan Micra 4 is to establish when it appears. Indeed, some problems can be connected to parts that are only stressed under certain conditions. It is this process that we will focus on in this first part.
Loud noise Nissan Micra 4 when accelerating
Loud noise on Nissan Micra 4 that happens 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 induce a much higher noise than during normal use. Moreover, it is also highly plausible that loud noise on your Nissan Micra 4 is in connection 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 gains speed.

When my Nissan Micra 4 is stopped
If your Nissan Micra 4 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 cause.
Where does loud noise come from on my Nissan Micra 4 and how can I be sure of its origin?
Now that we have determined the origin of the noise, we will look into the verification step to be sure that this is the issues you are encountering.

The loud noise comes from the wheels of my Nissan Micra 4
As we have seen previously, loud noise from the wheels of your Nissan Micra 4 may be connected to two main trouble. 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 right away. 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 Nissan Micra 4 that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your auto technician to swap the tires or perform a balancing.

The loud noise comes from the engine of my Nissan Micra 4
In case you have discovered loud noise as coming from the engine of your Nissan Micra 4, 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 experience a power loss during your acceleration. If the loud noise on your Nissan Micra 4 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 generate 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 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 4, 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 Nissan Micra 4, 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 vehicle 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.
