When does my Ford Focus C-max produce a loud noise?
One way to identify a noise from your Ford Focus C-max is to establish when it shows up. Indeed, some trouble can be connected to parts that are only stressed under certain circumstances. It is this method that we will focus on in this first part.
Loud noise Ford Focus C-max when accelerating
Loud noise on Ford Focus C-max that happens when you are accelerating can be symptomatic of different failures. In fact, if you encounter 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 operation. Moreover, it is also highly plausible that loud noise on your Ford Focus C-max is associated with 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 Focus C-max is stopped
If your Ford Focus C-max makes a loud noise while not accelerating, engine on, the problem may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.

Now that we have uncovered the cause of the noise, we will deal with the verification stage to be sure that this is the issues you are going through.

The loud noise comes from the wheels of my Ford Focus C-max
As we have seen before, loud noise from the wheels of your Ford Focus C-max may be linked to 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 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 change it or them as soon as possible. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Ford Focus C-max that is the matter, 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 technician to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Ford Focus C-max
In case you have identified loud noise as coming from the engine of your Ford Focus C-max, 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 encounter a power loss during your acceleration. If the loud noise on your Ford Focus C-max 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 service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Ford Focus C-max, it is highly plausible 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 Ford Focus C-max, 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 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.
