It is hardly ever enjoyable to hear an injector noise on your Volkswagen Touran 3. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this symptom may be related to several types of concerns with your car injectors. It may not be anything serious, but when a recurrent noise happens, you have to be sure. Most importantly since fixing your Volkswagen Touran 3’s injectors can be expensive. That’s why our team chose to produce this article content in order to support you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Volkswagen Touran 3, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very significant element of the operation of your engine. They were released to the modern cars 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled from the various sensors equipping the car (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 reasons of a clicking or knocking noise caused by the injectors of your Volkswagen Touran 3
Experiencing injector noises on your Volkswagen Touran 3 may originate from different origins, we will now focus on the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to get rid of them. If you hear another clicking noise but it is not from your injectors, we advise you to browse this article content about clicking noise on Volkswagen Touran 3 to find the cause.
The causes for injector clicking or knocking noise Volkswagen Touran 3
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Volkswagen Touran 3 have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions 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 Touran 3. 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 obstruction will inevitably end up in a malfunction of the injector.

The effects of injector noise on Volkswagen Touran 3
Now that we have reviewed the diverse causes for injector noise on your Volkswagen Touran 3, we will end by stating the possible effects 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 fairly 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 common effects felt by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks associated with 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>
