The loud noise comes from the wheels of my Citroen Cactus

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 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 Citroen Cactus that is the issue, you will tend to feel a vibration in the direction of the automobile as you go faster.

The loud noise comes from the engine of my Citroen Cactus
In case you have recognized loud noise as coming from the engine of your Citroen Cactus, 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 Citroen Cactus 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 cause 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 automobile to your garage .

To confirm this, get help from someone who will stand under the car while you accelerate to find the exact area of origin of this noise.
