When does my Ford Mondeo 4 produce a loud noise?

Loud noise Ford Mondeo 4 when accelerating
Loud noise on Ford Mondeo 4 that starts when you are accelerating can be symptomatic of multiple failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will generate a much higher noise than during normal use. Furthermore, it is also highly plausible that loud noise on your Ford Mondeo 4 is related to a wheel bearing, which is one of the most common origins of these types of signs of illness. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Ford Mondeo 4 is stopped
If your Ford Mondeo 4 makes a loud noise while not accelerating, engine on, the problem may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.

The loud noise comes from the wheels of my Ford Mondeo 4
As we have seen before, loud noise from the wheels of your Ford Mondeo 4 may be related 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 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 change it or them as soon as possible. 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 Ford Mondeo 4 that is the issue, 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 mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Ford Mondeo 4
In case you have recognized loud noise as coming from the engine of your Ford Mondeo 4, 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 Ford Mondeo 4 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 examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your car to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Ford Mondeo 4, it is highly plausible that you have rust if your vehicle is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Ford Mondeo 4, 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 vehicle 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.
