Yech - I hope not.  That would imply that we're stuck with it.  I also worry
about fatiguing other parts due to the twisting.

Maybe it's a combination, where the engine twisting is feeding back into the
throttle linkage or something.  I can't believe, given Audi pilots' appetite
for performance, that this would have gone un-noticed in testing (if it is,
in fact, an intrinsic problem in the engine mount design).

I intend to be pretty stubborn about this when I take it to the dealer since
I intend on keeping my A4Q for quite a while and I don't want to end up
replacing a bunch of torque-fatigued parts a few years from now... right
after the warranty expires.
