Why is my Audi 80 making a weird noise under the hood?

Lately, I've been noticing a strange noise coming from under the hood of my Audi 80. It sounds like a low-pitched humming and I'm worried it might be a sign of a bigger problem. Has anyone else experienced this issue and if so, what could be causing it?

Hi Sandra, I would recommend taking your Audi 80 to a trusted mechanic as soon as possible. It's important to get any unusual noises checked out right away before they turn into larger and more expensive problems. It could be something as simple as a loose belt or it could be a more serious issue with the engine. Better to be safe than sorry.
