I acknowledge a clicking noise coming from my high engine
If you acknowledge an engine noise on Mercedes Classe B, and this noise is based at the top of the engine, it means that it is based at your cylinder head and accompanying elements. Two elements can be the causes of these engine noises on Mercedes Classe B. Either the hydraulic pushers, generally it is because of their defective “hydraulic catch-up” system that we will acknowledge these clicking noises, often when cold and goes away when hot.

I acknowledge an engine clicking noise on Mercedes Classe B coming from combustion
Finally, if you think that this clicking noise is relating to the combustion of your engine, there are three plausible triggers of it. Verify the condition of your glow plugs which if worn can hinder the proper combustion of the fuel mixture. Then, your timing belt may be shifted and may poorly control the timing of the various engine elements to provide good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors is injured. In this case, do not be reluctant to read this content which deals in detail with the distinct injector noises on Mercedes Classe B.
Hissing noise / engine friction Mercedes Classe B
Engine noise Mercedes Classe B close to a bearing
If it is close to a squeaking noise you may have one of the bearings of your engine accessory parts that are reached. So check the condition and try to find the exact source of this noise by positioning someone at the engine at idle, and if this noise is more likely to show up in high rpm, accelerate and position someone at the engine block to discover the region of origin of the noise. The three elements whose bearings are often at the origin of these noises are the water pump, the injection pump and the oil pump.

Engine noise Mercedes Classe B close to a friction
In the event that you acknowledge a motor noise on your Mercedes Classe B, and, that this noise is close to a friction, it is likely that one of your belts or one of the elements that triggers it is the origin of your problems.Often, we will start to acknowledge a motor noise on Mercedes Classe B, close to a friction when one of the belts is worn out or when one of the related parts like your alternator, or your tensioner roller is the trouble. So bear in mind to check their condition and go to your auto mechanic to swap the elements in question. If you have been able to target the noise as coming from the belts and you want more information about it, check this content on belt noise on Mercedes Classe B for a complete guide.
Metal motor noise Mercedes Classe B
In the event that you acknowledge an engine noise on Mercedes Classe B and this noise is similar to metal noise, it is plausible that this noise comes from your gearbox or clutch. In fact, a metallic noise in the engine block is often linked to damaged sprockets. Try to check that this noise comes from the transmission, if this is the case, as soon as possible go to your mechanic or you would get a break down. Finally, the second possibility is that your silent engine blocks or rubber mounts may be dead. This triggers a metallic noise each time your engine moves, either because of a change of pace (acceleration or braking) or, when you pass on roads in poor condition. Verify the condition of your silentblocks and swap them if needed.
