When does my Renault Grand Espace make a loud noise?
One way to find a noise from your Renault Grand Espace is to identify when it appears. Indeed, some complications can be related to parts that are only stressed under certain circumstances. It is this technique that we will focus on in this first part.
Loud noise Renault Grand Espace when accelerating
Loud noise on Renault Grand Espace that occurs when you are accelerating can be symptomatic of different failures. In fact, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will generate a much higher noise than during normal use. Additionally, it is also highly plausible that loud noise on your Renault Grand Espace is linked to a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative 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 Renault Grand Espace is stopped
If your Renault Grand Espace makes a loud noise while not accelerating, engine on, the problem may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the induce.
Where does loud noise come from on my Renault Grand Espace and how can I be sure of its origin?
Now that we have found the origin of the sound, we will concentrate on the verification step to ensure that this is the concern you are experiencing.

The loud noise comes from the wheels of my Renault Grand Espace
As we have seen earlier in this article, loud noise from the wheels of your Renault Grand Espace 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 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 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 Renault Grand Espace that is the issue, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to swap the tires or do a balancing.

The loud noise comes from the engine of my Renault Grand Espace
In case you have discovered loud noise as coming from the engine of your Renault Grand Espace, 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 Renault Grand Espace 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 verify that the engine idle speed is not random. In case you confirm one of these two trouble, take your vehicle to your mechanic .

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