When you detect irregular noises on your Volkswagen Polo you tend to concerns about them. Specifically when you feel a noise when you accelerate on your Volkswagen Polo. It is right away assimilated to an engine motor issue and can therefore be significant. As we know that you do not take these problems lightly, we have made a decision to produce this article to help you find the causes and eliminate this concern as quickly as possible. To do this, we will first see what are the oeigins of a high pitched noise when accelerating with my Volkswagen Polo, then what is a whistling or ratling noise at the acceleration of my Volkswagen Polo, then the origins of a noise that intensifies during acceleration and to finish a noise that ends when I stop accelerating.
Ma Volkswagen Polo makes a high-pitched noise when I accelerate:
If your Volkswagen Polo makes a loud noise when you accelerate, it is quite possible that the alternator belt is the reason of your issue. You will need to establish if this noise shows up suddenly and if it can stop as it started. The alternator belt is a wearing part that is used to get power to the secondary components of your Volkswagen Polo’s engine and although it is less vital than the timing belt it can induce engine troubles if it fails. This sound may be a indicator of a slackened belt, in which case the tensioner roller or its wear and tear may be to blame. In any case, check the condition of your belt and its tension. If it causes this acceleration noise on Volkswagen Polo, go to your auto mechanic.
Ma Volkswagen Polo makes whining noise when I accelerate:
- Rattling or whistling noise caused by the turbo
- Humming noise caused by air leakage
If you have a power loss that comes with the rattling noise when you accelerate with your Volkswagen Polo, it is plausible that your turbo is failing and some of its components are at the end of their life. Check it and swap it if it is the reason, otherwise you risk clogging your engine in the long run. If you hear this blowing or whistling sound on your car, feel free to read this article about turbo noises on Volkswagen Polo, if you would like more info.
If, on the other hand, you do not experience any power loss due to an humming noise on your Volkswagen Polo, it is more than likely that you have one of your junctions or air hoses that has holes. So check the complete air supply system from your air filter to your engine to determine the starting point of this acceleration sound.
Ma Volkswagen Polo makes an increasingly loud noise when I accelerate:
If, on the other hand, you have the feeling that the more you gain speed, the more your noise at acceleration on Volkswagen Polo gets loud, then you will have to look at the rolling parts of your vehicle. Indeed, if this loud noise does not surface when you iddle, it is necessarily related to your transmission, and, in general, to your wheels. The most common reason is the state of your bearings, so make sure to check their state to make sure it is not the reason of this loud noise when you accelerate.

Ma Volkswagen Polo generates a noise when I accelerate that stops when I stop accelerating:
To finish, if you experience a noise when accelerating with your Volkswagen Polo and this noise which could be a cliking sound tends to end when you disengage (press the clutch pedal), then one of the wear parts of your clutch system may be the reason. Indeed, the clutch release bearings must be swapped around every 120 000 / 130 000km. To test it, you just have to see if you have more difficulty than usually shifting gears, if you feel a resistance either stronger or non-existent in the clutch pedal. If you have any of these manifestations, go to your mechanic to change the clutch release bearings on your Volkswagen Polo. Read our article on clutch noise on Volkswagen Polo for more information.
