The loud noise comes from the wheels of my Mercedes Sprinter 2
As we have seen previously, loud noise from the wheels of your Mercedes Sprinter 2 may be connected 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 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 change 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 Mercedes Sprinter 2 that is the trouble, 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 technician to change the tires or perform a balancing.

The loud noise comes from the engine of my Mercedes Sprinter 2

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 Mercedes Sprinter 2 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 cause 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 car to your service garage .

If the noise you have discovered comes from the exhaust pipe of your Mercedes Sprinter 2, 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 Mercedes Sprinter 2, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm this, get help from someone who will stand under the automobile 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.
