I recently took my tdi 1.9L jetta 2006 with 180k miles, to the dealer b/c it seemed to be running rough and possible misfiring. After running diagnostics they determined they problem was 1) Egr vacuum selanoid valve (stuck open) 2) The waste gate bypass valve 3) The air charge pressure sensor. After they replaced these 3 parts, (over $1000 including labor) the car is doing the same thing, he now says they need to replace the injector pump and all 4 injectors ($4200). Is there any way to confirm that it need these injectors and pump? Does anyone know any good tdi mechanics near albany ny?
