It is rarely ever pleasurable to notice an injector noise on your Peugeot 4008. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple types of problems with your vehicle injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Specifically since repairing your Peugeot 4008’s injectors can be expensive. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Peugeot 4008, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful element of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, 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 accumulated from the various sensors equipping the vehicle (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 origins of a clicking or knocking noise based on the injectors of your Peugeot 4008
Listening injector noises on your Peugeot 4008 may come from different sources, we will now concentrate on the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to get rid of them. If you notice another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Peugeot 4008 to find the reason.
The causes for injector clicking or knocking noise Peugeot 4008
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Peugeot 4008 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is modified, the main functionality 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 provoke thoses knocking or clicking noises on your Peugeot 4008. The main reason of these trouble usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector.

The side effects of injector noise on Peugeot 4008
Now that we have reviewed the diverse reasons for injector noise on your Peugeot 4008, 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 repercussions which can fairly quickly 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 regular effects noticed by drivers is a serious 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 degrading one of your pistons or your engine. Poor combustion will fairly quickly 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>
