When does my Renault Twizy produce a loud noise?
One way to detect a noise from your Renault Twizy is to determine when it appears. Indeed, some concerns can be related to components that are only stressed under certain occasions. It is this method that we will focus on in this first part.
Loud noise Renault Twizy when accelerating
Loud noise on Renault Twizy that starts 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 cause a much higher noise than during normal use. Additionally, it is also highly plausible that loud noise on your Renault Twizy is linked to a wheel bearing, which is one of the most common origins 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 issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Renault Twizy is stopped
If your Renault Twizy makes a loud noise while not accelerating, engine on, the issue may be linked 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 Renault Twizy and how can I be sure of its origin?
Now that we have determined the origin of the sound, we will deal with the verification stage to ensure that this is the matter you are having.

The loud noise comes from the wheels of my Renault Twizy
As we have seen earlier in this article, loud noise from the wheels of your Renault Twizy 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 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 swap it or them straight 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 Renault Twizy that is the problem, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your auto mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Renault Twizy
In case you have discovered loud noise as coming from the engine of your Renault Twizy, 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 experience a power loss during your acceleration. If the loud noise on your Renault Twizy 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 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 garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have noticed comes from the exhaust pipe of your Renault Twizy, 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 Renault Twizy, 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 origin 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.
