Check your high engine
If you hear a clicking noise on Audi A7, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Audi A7. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will perceive these clicking noises, often 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.
Check your low engine
If you have founded the area of origin of the Audi A7 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 fixes are very complex and most mechanics will suggest you to replace the engine of your Audi A7.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi A7 is linked to the combustion of your engine, there are three possible reasons of it. Check 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 trigger, comes from your injection, which is either blocked or one or more injectors are destroyed.

Check the condition of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Audi A7 is related to the direction of the automobile. 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 swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Check the rest of your direction
Finally, when you detect a clicking noise on your Audi A7, 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.

Check the suspension
If you experience a clicking noise on your Audi A7 when you pass a speed bump, it is extremely possible that your suspension block is the cause 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 function and during small jolts that compress the suspensions. To examine if this is the issue that concerns 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 promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Audi A7 at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a reason. To examine the shape of the spring, position the car 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 examine between the front and rear, if there is a gap too significant it suggests that that most likely your springs are worn, if you see 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 A7 than a clicking noise, don’t hesitate to consult this article.
