The loud noise comes from the wheels of my Opel Grandland X

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, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Opel Grandland X that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both cases, you will have to go to your mechanic to replace the tires or do a balancing.

The loud noise comes from the engine of my Opel Grandland X
In case you have identified loud noise as coming from the engine of your Opel Grandland X, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected 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 Opel Grandland X 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 trouble, take your car to your service garage .

If the noise you have detected comes from the exhaust pipe of your Opel Grandland X, 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 Grandland X, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure 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.
