Hello everyone. I was wondering if anyone has ever had a problem similar to mine because i have no idea what to look for. When im driving and im in gear there's a horrible grinding sound that starts to happen at just around 3000 rpm. the noise only occurs in first gear and second gear and occurs at the same rpm in both gears. the car runs fine other than the noise and there are no lights on. anyone heard of anything like this before???oh and the car is an 05 a4 with the 3 liter engine
