It is hardly ever relaxing to listen to an injector noise on your Citroen Berlingo. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to multiple sort of concerns with your car injectors. It may not be anything serious, but when a repeated noise arises, you have to be sure. Most importantly since replacing your Citroen Berlingo’s injectors can be costly. That’s why our team chose to compose 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 running and usefulness of the injectors in your Citroen Berlingo, then at the possible reasons from which an injector noise may come.injector-noise-citroen-berlingo

Attributes of the injectors

Injectors are a very useful part of the operation of your engine motor. They were released 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 ability, 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 received from the various sensors equipping the car (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 causes of a clicking or knocking noise based on the injectors of your Citroen Berlingo

Experiencing injector noises on your Citroen Berlingo may originate from different origins, we will now look into the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to get rid of them. If you listen to another clicking noise but it is not from your injectors, we encourage you to read this content page about clicking noise on Citroen Berlingo to find the cause.

The explanations for injector clicking or knocking noise Citroen Berlingo

A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Citroen Berlingo 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 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 tasks 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Citroen Berlingo. The main cause of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Citroen Berlingo, read this content page for more infos.

The consequences of injector noise on Citroen Berlingo

Now that we have analyzed the several reasons for injector noise on your Citroen Berlingo, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can quickly become serious….
First, you risk destroying your exhaust system 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 known effects felt by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading 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 suggestions to limit the risks linked 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>
