Being subject to constant noise on your car tends to be annoying, a car is so elaborate that it is constantly difficult to locate its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Volkswagen Polo 8, we will almost certainly be able to support you. Indeed, our editorial staff decided to compose this content page in order to review the main causes of a clicking noise on Volkswagen Polo 8. 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 sources of clicking noise on Volkswagen Polo 8 coming from your suspensions.
I hear a clicking noise on Volkswagen Polo 8 on my engine
Verify your high engine
If you hear a clicking noise on Volkswagen Polo 8, and this noise is located at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two elements can be the causes of these ticking noises on Volkswagen Polo 8. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will notice 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 situation, remember to change them.
Verify your low engine
If you have determined the region of source of the Volkswagen Polo 8 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 repairs are very complex and most mechanics will encourage you to swap the engine of your Volkswagen Polo 8.
Combustion problem
Finally, if you have the feeling that this clicking noise on Volkswagen Polo 8 is connected to the combustion of your engine, there are three possible origins of it. Verify the condition 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 elements to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to read this content page which deals in detail with the different injection sounds on Volkswagen Polo 8.
I hear a clicking noise on Volkswagen Polo 8 in my direction
Verify the condition of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Volkswagen Polo 8 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 create a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be replaced very quickly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it. If you would like more detailed information about gimbals noises on Volkswagen Polo 8, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you know a clicking noise on your Volkswagen Polo 8, 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 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 hear a clicking noise on Volkswagen Polo 8 coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Volkswagen Polo 8 once you pass a speed bump, it is highly plausible that your suspension block is the induce of the noise. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role and during small jolts that compress the suspensions. To check if this is the issue that worries you, take a dented road and, at low speed, pay attention to the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them soon as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Volkswagen Polo 8 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a cause. To check the shape of the spring, place the car 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 check between the front and rear, if there is a gap too significant 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 think about swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Volkswagen Polo 8 than a clicking noise, don’t hesitate to consult this article.
