When does my Bmw 1 series produce a loud noise?
One way to find a noise from your Bmw 1 series is to identify when it shows up. Indeed, some concerns can be linked to parts that are only stressed under certain occasions. It is this process that we will focus on in this first part.
Loud noise Bmw 1 series when accelerating
Loud noise on Bmw 1 series that occurs when you are accelerating can be symptomatic of multiple failures. Indeed, if you experience 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 operation. Furthermore, it is also highly possible that loud noise on your Bmw 1 series is associated with a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the trouble 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 Bmw 1 series
As we have seen earlier in this article, loud noise from the wheels of your Bmw 1 series may be in connection with 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 consider 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 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 Bmw 1 series that is the problem, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto technician to change the tires or do a balancing.

The loud noise comes from the engine of my Bmw 1 series
In case you have discovered loud noise as coming from the engine of your Bmw 1 series, 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 Bmw 1 series 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 trouble, take your vehicle to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have noticed comes from the exhaust pipe of your Bmw 1 series, it is highly possible 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 Bmw 1 series, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm 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.
