Being subject to regular noise on your automobile tends to be disturbing, a automobile is so elaborate 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 Volkswagen Polo, we will most likely be able to help you. Indeed, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Volkswagen Polo. This is why, firstly, we will see 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 Volkswagen Polo coming from your suspensions.
I find out a clicking noise on Volkswagen Polo from my engine
Verify your high engine
If you find out a clicking noise on Volkswagen Polo, 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. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, often when cold and go away 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 zone of source of the Volkswagen Polo clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, the risk in the long term is the breakage of the motor. These two fixes are very difficult and most mechanics will encourage you to replace the engine of your Volkswagen Polo.
Finally, if you have the feeling that this clicking noise on Volkswagen Polo is linked 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 possible that your timing belt is shifted and that it does not properly manage the timing of the various engine components to promote good combustion. And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to consult this content page which deals in detail with the different injection sounds on Volkswagen Polo.
I find out a clicking noise on Volkswagen Polo in my direction
Verify the condition of the gimbals
One of the most basic reasons of a clicking noises in the direction of your Volkswagen Polo is associated with the direction of the automobile. 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 approach the stop zone of your steering. A bellows with holes will harm the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it. If you would like more detailed information about gimbals noises on Volkswagen Polo, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you recognise a clicking noise on your Volkswagen Polo, it is possible 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 Volkswagen Polo coming from my suspensions
Verify the suspension
If you experience a clicking noise on your Volkswagen Polo when you pass a speed bump, it is really possible that your suspension block is the reason of the noise. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To examine if this is the trouble that concerns you, take a dented road and, at low speed, listen to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them as soon as possible as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Volkswagen Polo at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a explanation. To examine the state 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 similar 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, 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 changing it or them. If you have the feeling that this noise is more like a squeaking noise on Volkswagen Polo than a clicking noise, don’t hesitate to consult this article.
