Loud noise Porsche Cayenne when accelerating

Loud noise on Porsche Cayenne that occurs when you are accelerating can be symptomatic of different failures. In fact, if you feel a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will induce a much higher noise than during normal process. Furthermore, it is also highly possible that loud noise on your Porsche Cayenne is in connection with a wheel bearing, which is one of the most common causes of these types of signs of illness. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Porsche Cayenne is stopped

Where does loud noise come from on my Porsche Cayenne and how can I be sure of its origin?

Now that we have determined the origin of the noise, we will deal with the verification stage to be certain that this is the concern you are enduring.

  • The loud noise comes from the wheels of my Porsche Cayenne

    As we have seen previously, loud noise from the wheels of your Porsche Cayenne may be related 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 check 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 Porsche Cayenne that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both cases, you will have to go to your technician to change the tires or accomplish a balancing.

  • The loud noise comes from the engine of my Porsche Cayenne

    In case you have identified loud noise as coming from the engine of your Porsche Cayenne, 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 experience a power loss during your acceleration. If the loud noise on your Porsche Cayenne 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 generate an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check that the engine idle speed is not random. In case you confirm one of these two problems, take your vehicle to your mechanic .

  • Loud noise comes from the exhaust pipe of the vehicle

    If the noise you have found comes from the exhaust pipe of your Porsche Cayenne, 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 Porsche Cayenne, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure 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.
