I notice a clicking noise on BMW 5 Series from my engine
Examine your high engine
If you notice a clicking noise on BMW 5 Series, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on BMW 5 Series. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.
Examine your low engine
If you have determined the zone of origin of the BMW 5 Series 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 complicated and most mechanics will encourage you to swap the engine of your BMW 5 Series.
Combustion problem
Finally, if you have the feeling that this clicking noise on BMW 5 Series is in connection with the combustion of your engine, there are three possible triggers 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.

Examine the condition of the gimbals
One of the most regular triggers of a clicking noises in the direction of your BMW 5 Series 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 get closer to the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be replaced very quickly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Examine the rest of your direction
Finally, when you find out a clicking noise on your BMW 5 Series, it is possible that it is the direction that is involved.

Examine the suspension
If you experience a clicking noise on your BMW 5 Series when you pass a speed bump, it is highly possible that your suspension block is the induce of the noise. In fact, 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 role and during small jolts that compress the suspensions. To check if this is the trouble 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 soon as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your BMW 5 Series at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a reason. To check the shape of the spring, place the automobile 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 check between the front and rear, if there is a gap too significant 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 changing it or them.
