Loud noise Opel Mokka when accelerating

In fact, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal use. Moreover, it is also highly possible that loud noise on your Opel Mokka is linked to a wheel bearing, which is one of the most common origins of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible 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 Opel Mokka
As we have seen previously, loud noise from the wheels of your Opel Mokka may be linked to two main trouble. 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 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 right away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Opel Mokka that is the trouble, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Opel Mokka
In case you have identified loud noise as coming from the engine of your Opel Mokka, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with 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 Opel Mokka 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 induce 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 mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Opel Mokka, it is highly possible 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 Opel Mokka, 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 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.
