   I have a VW TDI with 110K miles. I just overhauled the head do to a 
broke timing built. What I found with the VW is the intake/TB gets caked 
up from breather oil. Mine was restricted by about 50%. Yes mine smoked.
   The other thing is there is a sencer between the air filter box and 
TB. It regulates the fuel to the injectors by monitoring air flow. If 
this goes you should have a loss of power.
   Let me know if this helped.
