[Vwdiesel] Bucking TDI/ was "A new member in the family!"

[Fernando Fiore]

     To be honest, I really doubt that it is my fault, as it happens with me
and my dad both.  At first I did think it was, maybe doesn't have the same
low torque as the rabbit or something, too low of revs or my foot or
something.  But, I did it in the driveway, in neutral and gradually pressed
on the accelerator and the revs gradually increased, and found a point like
near 2000 RPM i believe where the tach oscillated a few hundred revs at a
very constant rate.  when it is warm and you repeat this procedure, this
does not happen.

Now that someone else has reported the problem, i really want to get tot he
bottom of this!
