Merro97 Posted May 24 Share Posted May 24 Hi all, new here so apologies if I do anything wrong. My A4 B8.5 S-Line CVT started making a whining noise around 6 weeks ago but not sure exactly when as the wife drives it usually and she never noticed it. There is a slight whine when idle that gets worse as the revs increase. Really hoping it isn’t related to the transmission in any way. I was thinking possibly the alternator failing or something to do with the belt? I’m rubbish with this stuff though. Wondering if anyone has any ideas before I take it into the shop? I’d be really thankful for any input on this. Vid of noise is linked: https://youtu.be/vil177hzwNk?si=YbEEo970Yh2D81Av Thank you all.

coaconi Posted September 1 Share Posted September 1 Hey, I have exact same noise. Did you find what issue is, or someone know what is problem? Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted September 1 Share Posted September 1 It sounds like a worn bearing. Slacken the belt and feel for loose bearings on the alternator, idler pulley, and everything else the belt comes into contact with. Quote Link to comment Share on other sites More sharing options...
