I perceive a clicking noise on Audi A5 from my engine
Examine your high engine
If you perceive a clicking noise on Audi A5, and this sound is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Audi A5. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will perceive 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 identified the zone of source of the Audi A5 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 maintenance are very complex and most mechanics will advise you to replace the engine of your Audi A5.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi A5 is connected to the combustion of your engine, there are three possible reasons 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 trigger, comes from your injection, which is either blocked or one or more injectors are injured. In this case, do not hesitate to consult this article which deals in detail with the different injection sounds on Audi A5.
I perceive a clicking noise on Audi A5 in my direction
Examine the condition of the gimbals
One of the most common reasons of a clicking noises in the direction of your Audi A5 is linked 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 make 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 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 recognise a clicking noise on your Audi A5, 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 perceive a clicking noise on Audi A5 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Audi A5 each time you pass a speed bump, it is really conceivable that your suspension block is the induce of the sound. In fact, 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 role 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 coming 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 are subject to a clicking noise on your Audi A5 at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a reason. To verify the shape 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 verify between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you see a leak go a little further in the article to have the solution 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 consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Audi A5 than a clicking noise, don’t hesitate to consult this article.
