Being subject to constant noise on your car tends to be annoying, a car is so complex that it is constantly difficult to find its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Audi S5, 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 Audi S5. This is why, firstly, we will check out 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 sources of clicking noise on Audi S5 coming from your suspensions.
I notice a clicking noise on Audi S5 on my engine
Check your high engine
If you notice a clicking noise on Audi S5, and this sound is located 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 Audi S5. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will perceive 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 case, remember to change them.
Check your low engine
If you have distinguished the area of origin of the Audi S5 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 maintenance are very complicated and most mechanics will recommend you to change the engine of your Audi S5.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi S5 is linked to the combustion of your engine, there are three possible causes of it. Check 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 case, do not hesitate to check this content page which deals in detail with the different injection sounds on Audi S5.
I notice a clicking noise on Audi S5 in my direction
Check the condition of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Audi S5 is related to 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 make a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will affect 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. If you would like more detailed information about gimbals noises on Audi S5, do not hesitate to consult this complete guide.
Check the rest of your direction
Finally, when you experience a clicking noise on your Audi S5, 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 notice a clicking noise on Audi S5 coming from my suspensions
Check the suspension
If you experience a clicking noise on your Audi S5 once you pass a speed bump, it is very plausible that your suspension block is the cause 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 worries you, take a dented road and, at low speed, listen to 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 notice a clicking noise on your Audi S5 at the suspension level, it is highly plausible that spring wear or shock cylinder deformation may be a explanation. To check the condition 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 similar 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 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 think about replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi S5 than a clicking noise, don’t hesitate to consult this article.
