Being subject to regular noise on your car tends to be disturbing, a car is so elaborate that it is usually difficult to locate its origin and even more so to find the part that generates it. If you have already experienced a clicking noise on your Audi S3, we will most likely be able to help you. In fact, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Audi S3. This is why, firstly, we will see 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 Audi S3 coming from your suspensions.

Verify your high engine
If you listen to a clicking noise on Audi S3, 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 elements can be the triggers of these ticking noises on Audi S3. 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 go away when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.
Verify your low engine
If you have founded the area of origin of the Audi S3 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 complicated and most mechanics will encourage you to change the engine of your Audi S3.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi S3 is in connection with the combustion of your engine, there are three possible causes of it. Verify the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is possible 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 reason, comes from your injection, which is either blocked or one or more injectors are damaged. In this circumstance, do not hesitate to check this document which deals in detail with the different injection sounds on Audi S3.

Verify the condition of the gimbals
One of the most common reasons of a clicking noises in the direction of your Audi S3 is connected 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 get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Verify the rest of your direction
Finally, when you recognise a clicking noise on your Audi S3, it is possible 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.

Verify the suspension
If you experience a clicking noise on your Audi S3 when you pass a speed bump, it is very possible that your suspension block is the cause of the sound. In fact, 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 verify if this is the problem 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 affect other parts and require more expensive repairs.
Check spring and cylinder
If you are subject to a clicking noise on your Audi S3 at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a explanation. To verify 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 equivalent on each side (empty car for measurement). You can also verify 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, 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 replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi S3 than a clicking noise, don’t hesitate to consult this article.
