It is rarely ever relaxing to listen to an injector noise on your Volkswagen Caddy. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indication may be related to multiple kind of concerns with your automobile injectors. It may not be anything serious, but when a continuing noise appears, you have to be sure. Most importantly since fixing your Volkswagen Caddy’s injectors can be costly. That’s why our team chose to write this article in order to support you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Caddy, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant element of the operation of your engine. They were released 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 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 compiled from the various sensors equipping the automobile (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 causes of a clicking or knocking noise based on the injectors of your Volkswagen Caddy
Experiencing injector noises on your Volkswagen Caddy may originate from different origins, we will now look into the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be used to prevent them. If you listen to another clicking noise but it is not from your injectors, we encourage you to read this article about clicking noise on Volkswagen Caddy to discover the reason.
The explanations for injector clicking or knocking noise Volkswagen Caddy
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Volkswagen Caddy 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 mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is altered, the main role 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 induce thoses knocking or clicking noises on your Volkswagen Caddy. The main reason of these trouble in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Volkswagen Caddy, check this article for more infos.
The end result of injector noise on Volkswagen Caddy
Now that we have reviewed the different causes for injector noise on your Volkswagen Caddy, we will end by stating the possible side 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 consequences which can quickly become considerable….
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 consequences noticed by drivers is a significant loss of power. In fact, 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 affect 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 changing your diesel fuel filter regularly>
