Why does my Audi 80 make a loud screeching noise while in reverse?

Recently, my Audi 80 has been making a loud screeching noise when I put it in reverse. It doesn't happen all the time, but when it does, it's quite alarming. I'm not sure what could be causing it and if it's something I should be concerned about.

It sounds like your brake pads might be worn out. When they get low, they can start to make a loud screeching noise as they rub against the rotors. You should have them checked and replaced if necessary as it can affect your vehicle's braking performance.

It could be an issue with your transmission. If the screeching noise is also accompanied by difficulty shifting gears, it's likely that your transmission is experiencing problems. You should take your Audi to a mechanic as soon as possible to get it checked out.

Have you checked your reverse gear? Sometimes, the gears can become worn or damaged and cause a screeching noise when put into reverse. It's a relatively easy fix and can be done by a mechanic.
