In addition, it is also highly plausible that loud noise on your BMW X6 is connected to a wheel bearing, which is one of the most common origins 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 plausible that the issue may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

The loud noise comes from the wheels of my BMW X6
As we have seen earlier in this article, loud noise from the wheels of your BMW X6 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 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 change it or them as soon as possible. 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 BMW X6 that is the trouble, you will tend to feel a vibration in the direction of the automobile as you go faster. In both situations, you will have to go to your auto technician to change the tires or execute a balancing.

The loud noise comes from the engine of my BMW X6
In case you have identified loud noise as coming from the engine of your BMW X6, 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 BMW X6 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 trouble, take your automobile 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 BMW X6, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your BMW X6, 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 car 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.
