It is never enjoyable to listen an injector noise on your Volkswagen Touareg. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to different types of complications with your automobile injectors. It may not be anything major, but when a persistent noise appears, you have to be sure. Most importantly since repairing your Volkswagen Touareg’s injectors can be costly. That’s why our team decided to write this article in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Touareg, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital component of the operation of your engine unit. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 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 obtained from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 coming from the injectors of your Volkswagen Touareg
Experiencing injector noises on your Volkswagen Touareg may originate from different origins, we will now concentrate on the potential causes of these. In most cases, 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 implemented to stop them. If you listen another clicking noise but it is not from your injectors, we advise you to examine this article about clicking noise on Volkswagen Touareg to discover the cause.
The reasons for injector clicking or knocking noise Volkswagen Touareg
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Volkswagen Touareg have three main missions, to manage 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 at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is altered, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Volkswagen Touareg. The main cause of these trouble in most cases 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. If after verifying, this noise comes from another element of the engine of your Volkswagen Touareg, have a look at this article for more informations.
The end result of injector noise on Volkswagen Touareg
Now that we have examined the different reasons for injector noise on your Volkswagen Touareg, 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 side effects which can promptly 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 repercussions felt by drivers is a distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
