I hear a clicking noise on Volkswagen Passat 8 from my engine
Examine your high engine
If you hear a clicking noise on Volkswagen Passat 8, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two parts can be the causes of these ticking noises on Volkswagen Passat 8. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally 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 case, remember to change them.
Examine your low engine
If you have determined the zone of origin of the Volkswagen Passat 8 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both circumstances, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will advise you to replace the engine of your Volkswagen Passat 8.
Combustion problem
Finally, if you have the feeling that this clicking noise on Volkswagen Passat 8 is related to the combustion of your engine, there are three possible reasons of it. Examine 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 elements 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 circumstance, do not hesitate to read this article which deals in detail with the different injection sounds on Volkswagen Passat 8.
I hear a clicking noise on Volkswagen Passat 8 in my direction
Examine the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Volkswagen Passat 8 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 generate a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped rapidly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Examine the rest of your direction
Finally, when you know a clicking noise on your Volkswagen Passat 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 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.

Examine the suspension
If you encounter a clicking noise on your Volkswagen Passat 8 when you pass a speed bump, it is extremely plausible that your suspension block is the induce of the sound. Indeed, it may be the suspension cups, which, when they are outdated, 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 verify if this is the issue 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 promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Volkswagen Passat 8 at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a explanation. 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 identical on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large 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, 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.
