It is never relaxing to notice a sound in your vehicle that you don’t know the cause of. So, what if you discern a loud noise that continues on your Volkswagen Caddy? It is highly plausible that this is a minor problem, but before beeing sure, it is better to operate some verifications. Whether that loud noise comes from the front of the vehicle, from the rear, whether it appears when you accelerate or when you are parked, our team has created this article to help you solve it. First, we will describe the possible explanations for the trouble according to when loud noise appears on your Volkswagen Caddy, and then we will look into the region of origin of the noise. In any case, if this noise remains, follow these recommendations to help you find the origin.

When does my Volkswagen Caddy produce a loud noise?
One way to identify a noise from your Volkswagen Caddy is to define when it appears. Indeed, some concerns can be linked to parts that are only stressed under certain types of conditions. It is this method that we will focus on in this first part.
Loud noise Volkswagen Caddy when accelerating
Loud noise on Volkswagen Caddy that shows up when you are accelerating can be symptomatic of multiple 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 provoke a much higher noise than during normal operation. Additionally, it is also highly plausible that loud noise on your Volkswagen Caddy 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 problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Volkswagen Caddy is stopped
If your Volkswagen Caddy makes a loud noise while not accelerating, engine on, the problem may be connected 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 Volkswagen Caddy and how can I be sure of its origin?
Now that we have uncovered the cause of the sound, we will deal with the verification step to ensure that this is the concern you are going through.

The loud noise comes from the wheels of my Volkswagen Caddy
As we have seen previously, loud noise from the wheels of your Volkswagen Caddy may be connected to two main disorders. 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 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 swap it or them quickly. 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 Volkswagen Caddy that is the problem, 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 auto mechanic to swap the tires or execute a balancing.

The loud noise comes from the engine of my Volkswagen Caddy
In case you have discovered loud noise as coming from the engine of your Volkswagen Caddy, 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 encounter a power loss during your acceleration. If the loud noise on your Volkswagen Caddy 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 verify 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 perceived comes from the exhaust pipe of your Volkswagen Caddy, 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 Volkswagen Caddy, 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 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.
