I have a 1.8t motor in my Passat; but, I had to replace my alternator last January....and I took some pics...I went from a 90 Amp Valeo to a 120 Amp Valeo....the pulley had to be switched over to the new rebuilt unit (I went to an Alternator/Starter shop) ....old one on the left (90 A Valeo)....new one on the right (120 A Valeo)....
Thanks for the help Waynep, ended up replacing the alternator itself and now its working like a charm!
I had a Valeo alternator from an 03 Jetta in my garage, so I slapped that in and made the connector work somehow. Its working perfect now. 14.5v almost instantly at startup. Weather is below 30F.
Bought the new Valeo, removed the Bosch, and got the Valeo installed. All is well, and I have a rebuildable Bosch 120A on hand-- no core charge w the new Alt.
