It is rarely ever pleasant to acknowledge an injector noise on your Mercedes Classe B 2. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be linked to several sort of problems with your automobile injectors. It may not be anything major, but when a repeated noise comes out, you have to be sure. Specifically since repairing your Mercedes Classe B 2’s injectors can be costly. That’s why our team decided to produce this content page in order to help you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Mercedes Classe B 2, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very significant part of the operation of your engine motor. They were released to the modern cars about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the possibility, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Mercedes Classe B 2
Listening injector noises on your Mercedes Classe B 2 may come from different locations, we will now center on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Mercedes Classe B 2 to find the reason.
The causes for injector clicking or knocking noise Mercedes Classe B 2
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Mercedes Classe B 2 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Mercedes Classe B 2. The main reason of these situations in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The effects of injector noise on Mercedes Classe B 2
Now that we have reviewed the diverse reasons for injector noise on your Mercedes Classe B 2, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can quickly become major….
First, you risk destroying your exhaust unit in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most basic consequences noticed by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected to your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of swapping your diesel fuel filter regularly>
