[Vwdiesel] [Audi-VW-Diesels] AAZ crank bolt

[Andrew .Libby]

The problem is not specifically the bolt, but rather the entire timing
sprocket/bolt/crank nose combination.  The problem is the key/keyway of the
sprocket.  The solution is to have the crank nose machined to accept the
later style sprocket for the early (pre-2000) TDI engines or swap cranks
entirely.  Simply replacing the bolt or sprocket with another AAZ one will
not help, but rather increase the risk due to the possibility of less
accurate torqueing than what the factory did.
