Loud noise Nissan Micra when accelerating
Loud noise on Nissan Micra that happens when you are accelerating can be symptomatic of several failures. Indeed, if you feel 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 use. In addition, it is also highly possible that loud noise on your Nissan Micra is linked to a wheel bearing, which is one of the most common origins 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 possible that the issue 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 Nissan Micra
As we have seen before, loud noise from the wheels of your Nissan Micra may be linked 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 consider to check 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, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Nissan Micra 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 mechanic to swap the tires or do a balancing.

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

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Nissan Micra, it is highly possible 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, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm 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.
