If you have already experienced a clicking noise on your Mercedes Gla, we will almost certainly be able to help you. In fact, our editorial staff decided to create this content page in order to review the main causes of a clicking noise on Mercedes Gla. This is why, firstly, we will check out 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 origins of clicking noise on Mercedes Gla coming from your suspensions.
I notice a clicking noise on Mercedes Gla from my engine
Check your high engine
If you notice a clicking noise on Mercedes Gla, 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 triggers of these ticking noises on Mercedes Gla. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, generally when cold and go away 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.
Check your low engine
If you have distinguished the area of source of the Mercedes Gla clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. 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 recommend you to swap the engine of your Mercedes Gla.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Gla is linked to the combustion of your engine, there are three possible origins of it. Check 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 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 damaged. In this case, do not hesitate to consult this content page which deals in detail with the different injection sounds on Mercedes Gla.
I notice a clicking noise on Mercedes Gla in my direction
Check the state of the gimbals
One of the most regular triggers of a clicking noises in the direction of your Mercedes Gla is connected 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 harm the cardan shaft very quickly and must be replaced rapidly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Check the rest of your direction
Finally, when you find out a clicking noise on your Mercedes Gla, 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 notice a clicking noise on Mercedes Gla coming from my suspensions
Check the suspension
If you experience a clicking noise on your Mercedes Gla once 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 check if this is the problem that worries you, take a dented road and, at low speed, pay attention to the sound originating 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 hear a clicking noise on your Mercedes Gla at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a cause. To check 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 check between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you discover 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 replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Gla than a clicking noise, don’t hesitate to consult this article.
