Being subject to repeated noise on your car tends to be irritating, a car is so complex that it is usually difficult to determine its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your BMW 2 Series, we will almost certainly be able to help you. Indeed, our editorial staff decided to create this document in order to review the main causes of a clicking noise on BMW 2 Series. This is why, firstly, we will see what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the origins of clicking noise on BMW 2 Series coming from your suspensions.
I find out a clicking noise on BMW 2 Series from my engine
Check your high engine
If you find out a clicking noise on BMW 2 Series, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two parts can be the triggers of these ticking noises on BMW 2 Series. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.
Check your low engine
If you have determined the region of origin of the BMW 2 Series clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two maintenance are very complicated and most mechanics will suggest you to change the engine of your BMW 2 Series.
Combustion problem
Finally, if you have the feeling that this clicking noise on BMW 2 Series is in connection with the combustion of your engine, there are three possible causes of it. Check the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable that your timing belt is shifted and that it does not properly manage the timing of the various engine parts to promote good combustion. And finally, the most classic trigger, comes from your injection, which is either blocked or one or more injectors are injured. In this case, do not hesitate to consult this document which deals in detail with the different injection sounds on BMW 2 Series.
I find out a clicking noise on BMW 2 Series in my direction
Check the state of the gimbals
One of the most basic causes of a clicking noises in the direction of your BMW 2 Series is linked with the direction of the car. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be changed in a short time, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on BMW 2 Series, do not hesitate to consult this complete guide.
Check the rest of your direction
Finally, when you experience a clicking noise on your BMW 2 Series, it is conceivable that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the case, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I find out a clicking noise on BMW 2 Series coming from my suspensions
Check the suspension
If you experience a clicking noise on your BMW 2 Series when you pass a speed bump, it is highly conceivable that your suspension block is the induce of the sound. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during small jolts that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and, at low speed, focus on the sound coming from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you are subject to a clicking noise on your BMW 2 Series at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a explanation. To verify the shape of the spring, position the vehicle on a flat surface and measure that the heights from the ground to the bottom of the body are equivalent on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you observe a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, ensure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on BMW 2 Series than a clicking noise, don’t hesitate to consult this article.
