When does my Volvo V50 generate a loud noise?

Loud noise Volvo V50 when accelerating
Loud noise on Volvo V50 that takes place when you are accelerating can be symptomatic of several failures. Indeed, if you encounter 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 Volvo V50 is in connection with a wheel bearing, which is one of the most common origins of these types of manifestations. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the problem 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 Volvo V50
As we have seen previously, loud noise from the wheels of your Volvo V50 may be linked 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 remember to examine 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 as soon as possible. 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 Volvo V50 that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your auto mechanic to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Volvo V50
In case you have recognized loud noise as coming from the engine of your Volvo V50, 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 experience a power loss during your acceleration. If the loud noise on your Volvo V50 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 examine that the engine idle speed is not random. In case you confirm one of these two problems, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Volvo V50, 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 Volvo V50, 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 starting point 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.
