Being subject to recurring noise on your vehicle tends to be disturbing, a vehicle is so complex that it is constantly 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 Serie 7, we will most likely be able to support you. In fact, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Bmw Serie 7. This is why, firstly, we will look at what are the reasons 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 Serie 7 coming from your suspensions.
I listen to a clicking noise on Bmw Serie 7 on my engine
Examine your high engine
If you listen to a clicking noise on Bmw Serie 7, and this sound is located at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Bmw Serie 7. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this case, remember to change them.
Examine your low engine
If you have distinguished the spot of origin of the Bmw Serie 7 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will advise you to replace the engine of your Bmw Serie 7.
Combustion problem
Finally, if you have the feeling that this clicking noise on Bmw Serie 7 is related to the combustion of your engine, there are three possible reasons of it. Examine the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible 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 damaged. In this circumstance, do not hesitate to check this document which deals in detail with the different injection sounds on Bmw Serie 7.
I listen to a clicking noise on Bmw Serie 7 in my direction
Examine the state of the gimbals
One of the most regular causes of a clicking noises in the direction of your Bmw Serie 7 is associated with the direction of the vehicle. 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage 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.

Examine the rest of your direction
Finally, when you find out a clicking noise on your Bmw Serie 7, it is plausible 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 circumstance, 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 listen to a clicking noise on Bmw Serie 7 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Bmw Serie 7 when you pass a speed bump, it is very plausible that your suspension block is the cause of the sound. In fact, 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 examine if this is the issue that concerns you, take a dented road and, at low speed, listen to the sound originating from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Bmw Serie 7 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a cause. To examine the condition of the spring, place 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 examine between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you discover a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, make sure 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 think about replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Bmw Serie 7 than a clicking noise, don’t hesitate to consult this article.
