When does my Volkswagen Beetle generate a loud noise?
One way to identify a noise from your Volkswagen Beetle is to define when it occurs. Indeed, some problems can be linked to parts that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise Volkswagen Beetle when accelerating
Loud noise on Volkswagen Beetle that shows up when you are accelerating can be symptomatic of several failures. Indeed, if you encounter 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 operation. Moreover, it is also highly possible that loud noise on your Volkswagen Beetle is in connection with a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Volkswagen Beetle is stopped

The loud noise comes from the wheels of my Volkswagen Beetle
As we have seen before, loud noise from the wheels of your Volkswagen Beetle may be linked to two main problems. 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 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 Volkswagen Beetle 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 technician to swap the tires or execute a balancing.

The loud noise comes from the engine of my Volkswagen Beetle
In case you have discovered loud noise as coming from the engine of your Volkswagen Beetle, 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 Volkswagen Beetle 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 verify 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 discovered comes from the exhaust pipe of your Volkswagen Beetle, 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 Volkswagen Beetle, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of source 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.
