The 97 Passat TDI had the same cooled EGR setup as the later A4s.  This,
along with the Castrol oil or the CF oil has probably lead to clogging of
the EGR valve and the manifold.  Remove the manifold and clean it.  It will
be REALLY nasty.  I let mine soak overnight in a good quality degreaser.
Use stem brushes etc to clean it all up. I used up 4 cans of brake cleaner
in the process.  My smoke, which had been building, disappeared except when
under had acceleration but then again, the Wett chip will do that.  Hayden
