If you have already experienced a clicking noise on your Audi A3, we will almost certainly be able to support you. Indeed, our editorial staff decided to write this document in order to review the main causes of a clicking noise on Audi A3. 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 A3 coming from your suspensions.
I find out a clicking noise on Audi A3 from my engine
Examine your high engine
If you find out a clicking noise on Audi A3, and this sound is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two elements can be the causes of these ticking noises on Audi A3. 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 state of wear that is at issue. In this circumstance, remember to change them.
Examine your low engine
If you have determined the zone of source of the Audi A3 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two maintenance are very complex and most mechanics will recommend you to change the engine of your Audi A3.
Finally, if you have the feeling that this clicking noise on Audi A3 is related to the combustion of your engine, there are three possible causes of it. Examine the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable 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 reason, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to read this document which deals in detail with the different injection sounds on Audi A3.
I find out a clicking noise on Audi A3 in my direction
Examine the condition of the gimbals
One of the most common triggers of a clicking noises in the direction of your Audi A3 is linked 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 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.

Examine the rest of your direction
Finally, when you experience a clicking noise on your Audi A3, it is conceivable 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 find out a clicking noise on Audi A3 coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Audi A3 once you pass a speed bump, it is really conceivable that your suspension block is the cause of the sound. 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 function and during small jolts that compress the suspensions. To verify if this is the problem that concerns 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 quickly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Audi A3 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a explanation. To verify the shape of the spring, place 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 verify 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 solution 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 consider changing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi A3 than a clicking noise, don’t hesitate to consult this article.
