You may already know this, but the alternator is an essential part of an engine. This is the one that guarantees to transform energy of the engine block of this Volkswagen Bora in Electricity supply in order to recharge the battery. If there is a problem, it could mainly cause electrical failures. It is therefore essential to pay attention to it. However, the malfunction could also come from your belt, sometimes pulleys. We will discover in this article where will be able to come from problems selon le noise which is issued.
Noise alternator belt on a Volkswagen Bora
La alternator belt, also called accessory belt, is the essential component that contributes to the good action of the alternator. It is it which, through its rotation, drives the alternator and creates electricity. However, it also serves to operate different pumps of the engine block. In the event that it destroys, it may make damages very serious in the engine of the Volkswagen Bora.
A metallic noise on the Volkswagen Bora:
This is a noise that generally comes Cold. The most common reason is that the streaks in the belt turn out to be deteriorated. However, it can also occur when the pulley is slightly offset. If the strap becomes loose it may naturally break. If you recognize this noise, it is best to replace the belt and the malfunction will be solved almost every time.

A slight hiss or breath on the Volkswagen Bora:
It's the opposite of the hassle before. The belt is certainly too tight or too short. You know what you need to do!
Alternator noise on a Volkswagen Bora
When it is indeed the alternator which produces this noise and not the belt, in this situation the problems are quite different. However, this noise may have similarities to that of a belt, which means a high hiss. The malfunction may result from a electrical failure, this remains fairly common. If the voltage essential for the proper functioning of the Volkswagen Bora is usually deficient, this is generally seen in the lack of alertness of the lights or lights within the vehicle. If ever the alertness is excessive, it happens that the battery indicator either in operation. In order to proceed with a voucher diagnostic of your malfunction, it is still quite possible to use a voltmeter to check the tension on the + and - of your battery, with the engine running naturally. Assuming that the voltage is found to be lower than that recommended on the battery, the malfunction will therefore come from the alternator. In this case, it usually needs to be replaced.
Conclusion:
A new alternator noise generally comes from the alternator belt, but can also come from the alternator itself. Economically, the alternator belt costs much less than the alternator.
