2002 TDI Chirp by steevz on 15 Oct, 2011 19:54

I have a chirpping noise coming from my TDI when I'm driving, but only when coasting. If you are applying gas there is no noise. Coasting there is noise, doesn't increase with speed or RPM just constant, and with brakes applied it's still there. Anyone have an ideas? Belt or tensioner maybe?

It's the alternator clutch pulley for sure.

Ac belt needs more tension.
