Being subject to constant noise on your car tends to be annoying, a car is so complex that it is generally difficult to situate its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your Volkswagen Lupo, we will most likely be able to support you. In fact, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Volkswagen Lupo. 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 Volkswagen Lupo coming from your suspensions.
I notice a clicking noise on Volkswagen Lupo on my engine
Examine your high engine
If you notice a clicking noise on Volkswagen Lupo, and this sound is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the triggers of these ticking noises on Volkswagen Lupo. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will notice these clicking noises, generally when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Examine your low engine
If you have identified the area of source of the Volkswagen Lupo clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very difficult and most mechanics will recommend you to replace the engine of your Volkswagen Lupo.
Combustion problem
Finally, if you have the feeling that this clicking noise on Volkswagen Lupo is connected 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 trigger, comes from your injection, which is either blocked or one or more injectors are destroyed. In this circumstance, do not hesitate to check this content page which deals in detail with the different injection sounds on Volkswagen Lupo.
I notice a clicking noise on Volkswagen Lupo in my direction
Examine the condition of the gimbals
One of the most regular causes of a clicking noises in the direction of your Volkswagen Lupo 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 rapidly, 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 Volkswagen Lupo, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you recognise a clicking noise on your Volkswagen Lupo, 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 notice a clicking noise on Volkswagen Lupo coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Volkswagen Lupo when you pass a speed bump, it is very plausible that your suspension block is the induce of the sound. In fact, 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 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 soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Volkswagen Lupo at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a explanation. To check the state of the spring, position the automobile 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 denotes 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, 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 consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Volkswagen Lupo than a clicking noise, don’t hesitate to consult this article.
