Being subject to constant noise on your automobile tends to be frustrating, a automobile is so elaborate that it is generally difficult to determine its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Audi A6, 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 A6. This is why, firstly, we will look at what are the causes 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 A6 coming from your suspensions.
I find out a clicking noise on Audi A6 from my engine
Examine your high engine
If you find out a clicking noise on Audi A6, and this noise 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 A6. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, often when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this case, remember to change them.
Examine your low engine
If you have determined the spot of source of the Audi A6 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. 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 recommend you to change the engine of your Audi A6.
Combustion problem
Finally, if you have the feeling that this clicking noise on Audi A6 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 possible that your timing belt is shifted and that it does not properly manage the timing of the various engine elements to promote good combustion. And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are destroyed. In this case, do not hesitate to consult this document which deals in detail with the different injection sounds on Audi A6.
I find out a clicking noise on Audi A6 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 A6 is connected 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 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 in a short time, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it. If you would like more detailed information about gimbals noises on Audi A6, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you recognise a clicking noise on your Audi A6, 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 find out a clicking noise on Audi A6 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Audi A6 when you pass a speed bump, it is very 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 task 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, pay attention to the noise coming from your front axle when you pass over holes. If these are the cups, consider changing them as soon as possible as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Audi A6 at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a explanation. To verify the condition 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 identical on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it denotes 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, 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 A6 than a clicking noise, don’t hesitate to consult this article.
