You may have hit a nerve there Stephen. Apparently VW South Africa terms
this condition "heterodyne", whatever that may be. It is only noticeable in
a quiet car, but with the radio on or chatting you can hardly detect it. VW
engines have never been silky-smooth, but this 2.0 litre engine in my Jetta
is reliable, strong & gutsy. If you want smooth, then drive a Toyota 1.3
sedan. I doubt anyone will pick up the resonance in a rwd vanagon.

....One of the problems I recall people talking about re: Eurospec
conversions
was a very irritating resonance or drumming noise from the motor at certain
rpm's. Many people said it was from the vibrations inherent in an inline
4cylinder motor. Are these same motors not making drumming noises in the
TiiCo conversions? Are the motor mounts different, or is this motor
different, or is something else different?.....
