When does my Opel Meriva produce a loud noise?
One way to detect a noise from your Opel Meriva is to determine when it appears. Indeed, some complications can be connected to components that are only stressed under certain types of conditions. It is this technique that we will focus on in this first part.
Loud noise Opel Meriva when accelerating
Loud noise on Opel Meriva that appears when you are accelerating can be symptomatic of several failures. Indeed, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal process. Additionally, it is also highly possible that loud noise on your Opel Meriva is connected to a wheel bearing, which is one of the most common causes of these types of manifestations. 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 increases speed.

When my Opel Meriva is stopped
If your Opel Meriva makes a loud noise while not accelerating, engine on, the issue may be in connection with 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 Opel Meriva
As we have seen before, loud noise from the wheels of your Opel Meriva may be in connection with two main problems. 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 consider 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 change it or them right away. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Opel Meriva that is the problem, 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 mechanic to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Opel Meriva
In case you have identified loud noise as coming from the engine of your Opel Meriva, 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 Opel Meriva 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 verify that the engine idle speed is not random. In case you confirm one of these two problems, take your automobile to your garage .

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