Title: 2002 TDI Chirp
Post by: steevz on October 15, 2011, 07:54:32 pm

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?
