No small wonder.  Our cars do NOT take lead :-)

It's not the computer geeks, it's the lawyers...and it's by far not
the first Audi to do this sort of thing.

For those bored and with 100/200 Bentleys hanging around, flip to
Volume 3, page 485...wiring diagram for the MC-II cars.  Note track
181...at the bottom, from the brake light switch, notice the link to
track 21.  Flip back to 469...whoa!  Lookee where it goes :-)

(of course, after drafting the message, I just remembered the 10vts
had that decel shutoff stuff, and I'm pretty sure its idle-switch
activated, but...murphy's law says that if you could be wrong about
something in a qlist posting, you will be, and the likelyhood of such
is proportional to how big an a$$ you'll look like if you are in fact
wrong.)

If I'm right about all this, bear in mind that I'm pretty sure the MC
has this too...so it's not from any unintended acceleration BS,
because that happened after the model year the MC was introduced.

Now, you're probably thinking, "ha, just snip that wire on the TT,
problem solved!"

Have fun trying to start the car, I suspect.  Now THAT particular
feature you can thank UA for.

I'd suggest possibly (after lots of due-diligence research)
installing a small switch, after triple-checking the wiring
diagram...to make sure you don't accidentally cut off, say, the
signal to the traction control/ABS.  Note back at our Bentley that if
you put a switch in before T10e/5, you'd be in for a truly nasty
surprise...no ABS.  I think you'd also want to do some QA testing to
make sure everything still worked, as well...

...unless of course the TT has some rocket-science pressure or
position sensor widget that it uses to figure out how hard the nut
behind the wheel is stomping, etc...in which case, probably best not
to touch it, and just stick with no LFB.

...and of course, if any Audi tech ever finds the switch, they'll go
looking to see what wire you cut, and promptly call up the Warantee
Card Ripping Department in Michigan.

Now here's a mind bender.  Guess what the 200q20v, one year later
-doesn't- have, according to the wiring diagrams?  Yep...
