However, I can give you some possible explanations for a whirring noise that starts with the ignition:
Potential Causes:
* Electric motor: The noise could be coming from a small electric motor associated with your power steering pump, air conditioning compressor, or a similar system.
* Belt tensioner: The whirring could be caused by a worn or malfunctioning belt tensioner.
* Alternator: A failing alternator can create a whirring noise, especially when it's under load.
* Water pump: Although less common, a worn water pump can produce a whirring sound.
Important Note: It is crucial to have your Volvo inspected by a qualified mechanic to identify the source of the noise and determine the necessary repairs.
Here's what you should do:
1. Listen closely: Pay attention to when the noise is loudest and if it changes in intensity. This can help a mechanic narrow down the source.
2. Consult a mechanic: Take your Volvo to a trusted mechanic specializing in Volvo vehicles. They will have the expertise to diagnose the problem and recommend the best course of action.
Remember, diagnosing car noises over the internet is unreliable and potentially dangerous. It's always best to consult a qualified mechanic for accurate diagnosis and repair.
