It is never relaxing to perceive a sound in your automobile that you don’t know the origin of. So, what if you recognize a loud noise that lasts on your CUPRA FORMENTOR? It is extremely plausible that this is a minor trouble, but before beeing sure, it is better to complete some checks. Whether that loud noise comes from the front of the vehicle, from the rear, whether it shows up when you accelerate or when you are parked, our team has created this content to help you fix it. First, we will detail the possible causes for the problem according to when loud noise shows up on your CUPRA FORMENTOR, and then we will focus on the region of origin of the noise. In any case, if this noise remains, follow these advice to help you find the source.

When does my CUPRA FORMENTOR make a loud noise?
One way to detect a noise from your CUPRA FORMENTOR is to determine when it shows up. Indeed, some concerns can be linked to components that are only stressed under certain conditions. It is this technique that we will focus on in this first part.
Loud noise CUPRA FORMENTOR when accelerating
Loud noise on CUPRA FORMENTOR that takes place when you are accelerating can be symptomatic of multiple failures. Indeed, if you experience 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 CUPRA FORMENTOR is related to 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 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 CUPRA FORMENTOR is stopped
If your CUPRA FORMENTOR makes a loud noise while not accelerating, engine on, the trouble may be connected 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 CUPRA FORMENTOR and how can I be sure of its origin?
Now that we have uncovered the cause of the sound, we will focus on the verification step to ensure that this is the concern you are going through.

The loud noise comes from the wheels of my CUPRA FORMENTOR
As we have seen before, loud noise from the wheels of your CUPRA FORMENTOR may be connected 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 keep in mind 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 replace it or them as soon as possible. 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 CUPRA FORMENTOR that is the trouble, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your technician to swap the tires or do a balancing.

The loud noise comes from the engine of my CUPRA FORMENTOR
In case you have discovered loud noise as coming from the engine of your CUPRA FORMENTOR, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated 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 CUPRA FORMENTOR 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 examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your CUPRA FORMENTOR, 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 CUPRA FORMENTOR, 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.
