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. In addition, it is also highly plausible that loud noise on your Mercedes Gla is connected to a wheel bearing, which is one of the most common causes of these types of symptoms. Another alternative 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.

When my Mercedes Gla is stopped
If your Mercedes Gla makes a loud noise while not accelerating, engine on, the issue 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.

The loud noise comes from the wheels of my Mercedes Gla
As we have seen before, loud noise from the wheels of your Mercedes Gla may be connected to two main disorders. 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 verify 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 quickly. 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 Gla that is the matter, 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 auto technician to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Mercedes Gla
In case you have discovered loud noise as coming from the engine of your Mercedes Gla, 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 Mercedes Gla 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 verify that the engine idle speed is not random. In case you confirm one of these two disorders, take your car 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 Mercedes Gla, 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 Gla, 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 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.
