Why does my Audi A6 make a strange noise?

When I start my Audi A6, it makes a strange noise that I've never heard before. It sounds like a high-pitched whirring or squealing noise. What could be causing this and what should I do about it?

Hi Samantha, it's likely that the noise you are hearing is coming from a failing air conditioning compressor. This can often be a sign that it needs to be replaced. It's best to take your Audi A6 to a certified mechanic to have it checked out.

Hey Samantha, another possible cause of the noise could be a failing alternator or serpentine belt. I recommend taking your Audi A6 to a trusted mechanic to have it inspected and repaired if necessary.

Hi Samantha, it could also be a problem with the power steering pump. If you notice any difficulty steering or a squealing noise when turning the wheel, then it's likely the power steering pump needs to be replaced. Have a mechanic take a look to confirm and make the necessary repairs.
