Ma Volkswagen Scirocco makes a high-pitched noise when I accelerate:
If your Volkswagen Scirocco makes a loud noise when you accelerate, it is quite conceivable that the alternator belt is the reason of your issue. You will need to identify if this noise shows up abruptly and if it can stop as it started. The alternator belt is a wearing part that is employed to get power to the secondary components of your Volkswagen Scirocco’s engine and although it is less vital than the timing belt it can generate engine damage if it fails. This sound may be a warning sign of a slackened belt, in which case the tensioner roller or its wear and tear may be responsible. In any case, verify the condition of your belt and its tension. If it causes this acceleration noise on Volkswagen Scirocco, go to your auto mechanic.
Ma Volkswagen Scirocco makes whining noise when I accelerate:
- Rattling or whistling noise created by the turbo
- Humming noise caused by air leakage
If you have a power loss that occurs with the rattling noise when you accelerate with your Volkswagen Scirocco, it is plausible that your turbo is screwing up and some of its parts are at the end of their life. Examine 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 document about turbo noises on Volkswagen Scirocco, if you would like more details.
If, on the other hand, you do not experience any power loss due to an humming noise on your Volkswagen Scirocco, it is more than likely that you have one of your junctions or air hoses that has holes. So verify the complete air supply system from your air filter to your engine to determine the origin of this acceleration sound.

Finally, if you experience a noise when accelerating with your Volkswagen Scirocco and this noise which could be a cliking sound tends to reduce when you disengage (press the clutch pedal), then one of the wear parts of your clutch system may be the cause. In fact, the clutch release bearings must be changed approximately every 120 000 / 130 000km. To test it, you just have to see if you have more difficulty than every time shifting gears, if you feel a resistance either stronger or non-existent in the clutch pedal. If you have any of these signs of illness, go to your technician to change the clutch release bearings on your Volkswagen Scirocco.
