Hello there, new to myturbodiesel, my 2006 vw jetta tdi 1.9 which was my wife's car and wich had recently started making a noise which I learned that was the clutch pulley after changing belt then tensioner, now it's making a noise where i saw on here that sounds like it could be from the cam but it starts of great flowing good then as I begin to exit highway a muffle sound begins kinda like a deep flapping then I park it and it goes away. My friend said it might be the Cadillac converter or the camshaft positioner sensor. I'm changing the timing belt this weekend and I'm going to check camshaft in the morning. Thank you so much for replying I appreciate it a lot. And I'm thinking of ordering a vcds. God Bless you all.
