Being subject to constant noise on your automobile tends to be annoying, a automobile is so sophisticated that it is generally 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 4, we will probably be able to support you. Indeed, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Volkswagen Polo 4. This is why, firstly, we will look at what are the origins 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 4 coming from your suspensions.
I listen to a clicking noise on Volkswagen Polo 4 from my engine
Examine your high engine
If you listen to a clicking noise on Volkswagen Polo 4, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on Volkswagen Polo 4. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will perceive 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 circumstance, remember to change them.
Examine your low engine
If you have founded the spot of source of the Volkswagen Polo 4 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 repairs are very complicated and most mechanics will advise you to replace the engine of your Volkswagen Polo 4.
Combustion problem
Finally, if you have the feeling that this clicking noise on Volkswagen Polo 4 is linked to the combustion of your engine, there are three possible reasons of it. Examine 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 components to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to read this document which deals in detail with the different injection sounds on Volkswagen Polo 4.
I listen to a clicking noise on Volkswagen Polo 4 in my direction
Examine the condition of the gimbals
One of the most common reasons of a clicking noises in the direction of your Volkswagen Polo 4 is connected to 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 create 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 replaced in a short time, 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 4, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you find out a clicking noise on your Volkswagen Polo 4, 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 listen to a clicking noise on Volkswagen Polo 4 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Volkswagen Polo 4 when you pass a speed bump, it is extremely plausible that your suspension block is the reason of the sound. 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 function and during small jolts that compress the suspensions. To check if this is the problem that worries you, take a dented road and, at low speed, focus on the sound originating from your front axle when ever you pass over holes. If these are the cups, consider changing them quickly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Volkswagen Polo 4 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a reason. To check the shape 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 identical 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 discover a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, be 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 Volkswagen Polo 4 than a clicking noise, don’t hesitate to consult this article.
