It is rarely ever pleasant to notice an injector noise on your Peugeot 208. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indicator may be related to multiple kind of trouble with your car injectors. It may not be anything serious, but when a continuing noise happens, you have to be sure. Specifically since fixing your Peugeot 208’s injectors can be costly. That’s why our team chose to create this content page in order to support 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 Peugeot 208, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant component of the operation of your engine motor. They were brought in to the modern automobiles about 20 years ago. Before their arrival, 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 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 reasons of a clicking or knocking noise caused by the injectors of your Peugeot 208
Discovering injector noises on your Peugeot 208 may originate from different origins, we will now focus 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 stop them. If you notice another clicking noise but it is not from your injectors, we suggest you to go through this content page about clicking noise on Peugeot 208 to find the reason.
The explanations for injector clicking or knocking noise Peugeot 208
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Peugeot 208 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Peugeot 208. The main reason of these concerns 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 cause a malfunction of the injector.

The repercussions of injector noise on Peugeot 208
Now that we have reviewed the different reasons for injector noise on your Peugeot 208, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become critical….
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 known consequences 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 undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
