You may already know this, however the alternator is a fundamental component in an engine. It is himself who is responsible for transforming energy of the engine block of this Volkswagen Golf 7 Sw in Electricity supply in order to recharge the battery. In the specific case where there is a problem, it can thus mainly cause electrical failures. It therefore seems important to resolve the problem. However, the problem may also come from your belt, sometimes pulleys. We will see through this post where will be able to come problems related to noise which is issued.noise-alternator-Volkswagen-Golf-7-Sw

Noise alternator belt on a Volkswagen Golf 7 Sw

La alternator belt, also called an accessory belt, is the essential component which contributes to the good action of the alternator. It is the latter which by its convolution drives the alternator and will make it possible to manufacture electricity. However, it also serves to train different pumps of the engine block. If it destroys, it could cause damages rather important within the engine of this Volkswagen Golf 7 Sw.

A metallic noise on the Volkswagen Golf 7 Sw:

This is a noise that generally comes Cold. The most common reason is that the streaks on this strap will be damaged. However it could also happen when the pulley is a little out of gon. If the belt breaks down, it could obviously break. If you distinguish this sound, the ideal will be to replace the belt and the problem will be repaired almost without fail.

A sharp squeal on the Volkswagen Golf 7 Sw:

This remains the most common, as well as the least significant, dysfunction. It usually comes out cold, but may reappear when you sometimes drive. However, it stops suddenly. This problem often occurs when the accessory belt is not tight enough. It will suffice tighten and it's won. Be careful, if it stays in this state for too long, the belt could become damaged and cause a more dramatic problem in the long run. This sharp squeak also sometimes occurs when the damper pulley is damaged, however it is rather rare.

A slight hiss or breath on the Volkswagen Golf 7 Sw:

It is the opposite of the previous dysfunction. Your belt is certainly excessively tight or too small. You know what you have left to do !

Alternator noise on a Volkswagen Golf 7 Sw

In the event that it is really the alternator that makes the sound and not the belt, then the hassle will be totally divergent. Nevertheless, the sound emitted could have similarities compared to that of a strap, so a high hiss. The concern may arise from a electrical failure, this remains relatively ordinary. If it happens that the voltage essential to the good activity of the Volkswagen Golf 7 Sw remains deficient, it can often be seen in the lack of intensity of the lights or bulbs inside the vehicle. In case the lack of intensity is out of the ordinary, it happens that the battery indicator stays on. In order to make a real diagnostic of your concern, it is quite feasible to use a voltmeter and take the tension on the plus and minus of the battery, the ignition on naturally. If the voltage is lower than that recommended by the battery, the problem could therefore come from the alternator. So, it usually needs to be replaced.

Conclusion:

A new alternator sound generally comes from the alternator belt, but may also come from the alternator itself. Economically, an alternator belt is much cheaper compared to the alternator. Get a quote from a auto repairer before embarking on repairs, as you can never be sure of the source of the problem. We hope this post helped you, if so don't hesitate to leave a comment. Have a good ride with your Volkswagen Golf 7 Sw.
