The loud noise comes from the wheels of my Bmw Serie 6
As we have seen previously, loud noise from the wheels of your Bmw Serie 6 may be in connection with 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 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 swap it or them as soon as possible. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Bmw Serie 6 that is the trouble, you will tend to feel a vibration in the direction of the automobile as you go faster. In both cases, you will have to go to your technician to swap the tires or perform a balancing.

The loud noise comes from the engine of my Bmw Serie 6
In case you have recognized loud noise as coming from the engine of your Bmw Serie 6, 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 Bmw Serie 6 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 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 disorders, take your automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Bmw Serie 6, it is highly plausible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Bmw Serie 6, 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 automobile 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.
