Being subject to regular noise on your vehicle tends to be frustrating, a vehicle 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 Passat , we will most likely be able to support you. Indeed, our editorial staff decided to write this article in order to review the main causes of a clicking noise on Volkswagen Passat . This is why, firstly, we will see 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 sources of clicking noise on Volkswagen Passat coming from your suspensions.
I perceive a clicking noise on Volkswagen Passat located on my engine
Check your high engine
If you perceive a clicking noise on Volkswagen Passat , and this noise 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 triggers of these ticking noises on Volkswagen Passat . 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 go away 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.
Check your low engine
If you have distinguished the area of origin of the Volkswagen Passat clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two repairs are very complex and most mechanics will suggest you to swap the engine of your Volkswagen Passat .
Combustion problem
Finally, if you have the feeling that this clicking noise on Volkswagen Passat is related to the combustion of your engine, there are three possible reasons of it. Check 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 destroyed. In this case, do not hesitate to read this article which deals in detail with the different injection sounds on Volkswagen Passat .
I perceive a clicking noise on Volkswagen Passat in my direction
Check the state of the gimbals
One of the most regular causes of a clicking noises in the direction of your Volkswagen Passat is connected to 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 harm 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 Passat , do not hesitate to read this complete guide.
Check the rest of your direction
Finally, when you experience a clicking noise on your Volkswagen Passat , 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 perceive a clicking noise on Volkswagen Passat coming from my suspensions
Check the suspension
If you encounter a clicking noise on your Volkswagen Passat each time you pass a speed bump, it is very 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 verify if this is the issue that concerns you, take a dented road and, at low speed, focus on the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Volkswagen Passat at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a cause. To verify the condition of the spring, position 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 verify between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you observe a leak go a little further in the article to have the solution 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 Passat than a clicking noise, don’t hesitate to consult this article.
