The loud noise comes from the wheels of my Citroen Saxo
As we have seen previously, loud noise from the wheels of your Citroen Saxo 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 consider to check 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, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Citroen Saxo that is the trouble, you will tend to feel a vibration in the direction of the vehicle 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 Citroen Saxo
In case you have recognized loud noise as coming from the engine of your Citroen Saxo, 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 Citroen Saxo 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 induce an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check that the engine idle speed is not random. In case you confirm one of these two problems, take your vehicle to your garage .

Loud noise comes from the exhaust pipe of the vehicle

To validate this, get help from someone who will stand under the car 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.
