Check your high engine
If you listen to a clicking noise on Mercedes Sprinter, and this noise is based at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two parts can be the causes of these ticking noises on Mercedes Sprinter. 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 go away 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 identified the spot of origin of the Mercedes Sprinter 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 repairs are very complicated and most mechanics will advise you to replace the engine of your Mercedes Sprinter.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Sprinter 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 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 injured. In this circumstance, do not hesitate to read this article which deals in detail with the different injection sounds on Mercedes Sprinter.

Check the condition of the gimbals
One of the most common triggers of a clicking noises in the direction of your Mercedes Sprinter is associated with 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 create 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 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 know a clicking noise on your Mercedes Sprinter, 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 encounter a clicking noise on your Mercedes Sprinter once you pass a speed bump, it is highly possible that your suspension block is the cause of the noise. Indeed, it may be the suspension cups, which, when they are out of date, 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 verify if this is the problem that concerns you, take a dented road and, at low speed, listen to the noise originating 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 notice a clicking noise on your Mercedes Sprinter at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a explanation. To verify 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 verify between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you observe 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 Mercedes Sprinter than a clicking noise, don’t hesitate to consult this article.
