When does my Vauxkhall Astra generate a loud noise?
One way to discern a noise from your Vauxkhall Astra is to establish when it occurs. Indeed, some complications can be linked to parts that are only stressed under certain types of conditions. It is this approach that we will focus on in this first part.
Loud noise Vauxkhall Astra when accelerating
Loud noise on Vauxkhall Astra that starts when you are accelerating can be symptomatic of different 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. Moreover, it is also highly plausible that loud noise on your Vauxkhall Astra is in connection with a wheel bearing, which is one of the most common origins 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 trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Vauxkhall Astra is stopped
If your Vauxkhall Astra makes a loud noise while not accelerating, engine on, the trouble may be related to 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 Vauxkhall Astra and how can I be sure of its origin?
Now that we have located the origin of the sound, we will focus on the verification stage to be sure that this is the issues you are having.

The loud noise comes from the wheels of my Vauxkhall Astra
As we have seen earlier in this article, loud noise from the wheels of your Vauxkhall Astra may be related to two main complications. 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 remember 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 right 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 Vauxkhall Astra 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 technician to replace the tires or execute a balancing.

The loud noise comes from the engine of my Vauxkhall Astra
In case you have discovered loud noise as coming from the engine of your Vauxkhall Astra, 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 Vauxkhall Astra 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 induce 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 problems, take your car to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Vauxkhall Astra, 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 Vauxkhall Astra, 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.
