I'm having issues with 2006 VW Jetta TDI 1.9. N17, and MAP Vacuum issues. Turbo is at full vacuum (closed) upon startup. If I disconnect the N17 or MAP sensors the turn works since it is fully open. Need someone's with vagcom to scan and help me figure out what is the issue. New turbo, new N17 installed. I'm at my wits end tryouts to diagnose the problem. I'm in West Valley City Utterly and really need help.
