It is rarely ever pleasurable to experience an injector noise on your Mercedes Benz E Class. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to different sort of trouble with your automobile injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Specifically since replacing your Mercedes Benz E Class’s injectors can be expensive. That’s why our team chose to produce this article in order to help you see more clearly, learn about the different possible failures and determine your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Mercedes Benz E Class, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful component of the operation of your engine motor. They were brought in to the modern vehicles 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 precisely (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 aim is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Mercedes Benz E Class
Discovering injector noises on your Mercedes Benz E Class may come from different sources, we will now center on the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to get rid of them. If you experience another clicking noise but it is not from your injectors, we advise you to examine this article about clicking noise on Mercedes Benz E Class to locate the trigger.
The explanations for injector clicking or knocking noise Mercedes Benz E Class
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Mercedes Benz E Class have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is modified, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Mercedes Benz E Class. The main trigger of these situations in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The side effects of injector noise on Mercedes Benz E Class
Now that we have analyzed the diverse causes for injector noise on your Mercedes Benz E Class, 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 promptly become severe….
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 regular effects experienced by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks associated with 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>
