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 sources of clicking noise on Renault Laguna coming from your suspensions.
I perceive a clicking noise on Renault Laguna located on my engine
Examine your high engine
If you perceive a clicking noise on Renault Laguna, and this noise 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 Renault Laguna. 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 condition of wear that is at issue. In this case, remember to change them.
Examine your low engine
If you have determined the region of source of the Renault Laguna 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 complicated and most mechanics will suggest you to change the engine of your Renault Laguna.
Combustion problem
Finally, if you have the feeling that this clicking noise on Renault Laguna is linked to the combustion of your engine, there are three possible triggers of it. Examine the state 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 check this document which deals in detail with the different injection sounds on Renault Laguna.
I perceive a clicking noise on Renault Laguna in my direction
Examine the state of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Renault Laguna is connected 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will harm 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 find out a clicking noise on your Renault Laguna, 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 Renault Laguna coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Renault Laguna once you pass a speed bump, it is extremely conceivable that your suspension block is the reason of the noise. 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 task 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, pay attention to 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 hear a clicking noise on your Renault Laguna at the suspension level, it is highly conceivable that spring wear or shock cylinder deformation may be a reason. To examine the shape of the spring, place 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 denotes that most likely your springs are worn, if you find out 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 consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Renault Laguna than a clicking noise, don’t hesitate to consult this article.
