Chris,

Thanks for the thought, but this is a drive-by-wire throttle, that is, an
electronic wire. There is no cable. The throttle is moved by an electric
motor. It's all software magic - bad magic, in this case!

OOPS!!! I posted as a 1991 A4! I meant 2001. I don't think there was an
A4 in 1991, was there?
