It is never relaxing to experience an injector noise on your Mercedes Benz Sprinter. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indication may be connected to multiple kind of trouble with your automobile injectors. It may not be anything major, but when a persistent noise happens, you have to be sure. Specifically since replacing your Mercedes Benz Sprinter’s injectors can be costly. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mercedes Benz Sprinter, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental part of the operation of your engine. They were brought in to the modern automobiles 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 opportunity, 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 received 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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Mercedes Benz Sprinter
Experiencing injector noises on your Mercedes Benz Sprinter may originate from different sources, we will now center on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to eliminate them. If you experience another clicking noise but it is not from your injectors, we suggest you to browse this content page about clicking noise on Mercedes Benz Sprinter to find the trigger.
The reasons for injector clicking or knocking noise Mercedes Benz Sprinter
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Mercedes Benz Sprinter have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of 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 Sprinter. The main trigger of these problems commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Mercedes Benz Sprinter
Now that we have analyzed the different reasons for injector noise on your Mercedes Benz Sprinter, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these repercussions 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 repercussions experienced by drivers is a serious loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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>
