Being subject to frequent noise on your vehicle tends to be disturbing, a vehicle is so sophisticated that it is usually difficult to determine its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your Audi A2, we will most likely be able to support you. Indeed, our editorial staff decided to compose this content page in order to review the main causes of a clicking noise on Audi A2. This is why, firstly, we will look at 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 Audi A2 coming from your suspensions.
I hear a clicking noise on Audi A2 from my engine
Examine your high engine
If you hear a clicking noise on Audi A2, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two parts can be the causes of these ticking noises on Audi A2. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice 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 founded the area of origin of the Audi A2 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 advise you to replace the engine of your Audi A2.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi A2 is linked 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 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 cause, comes from your injection, which is either blocked or one or more injectors are injured. In this case, do not hesitate to read this content page which deals in detail with the different injection sounds on Audi A2.
I hear a clicking noise on Audi A2 in my direction
Examine the condition of the gimbals
One of the most regular reasons of a clicking noises in the direction of your Audi A2 is related 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 create a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be changed very quickly, 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 A2, 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 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 hear a clicking noise on Audi A2 coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Audi A2 when you pass a speed bump, it is really possible 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 function and during small jolts that compress the suspensions. To examine if this is the problem that concerns you, take a dented road and, at low speed, focus on the noise coming from your front axle when 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 detect a clicking noise on your Audi A2 at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a reason. To examine the condition 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 equivalent on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too significant 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, 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 replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi A2 than a clicking noise, don’t hesitate to consult this article.
