Yep, that's what my '85 4000 does when it hits 67-6800 rpm...

When I had Techtonics Tuning build a Solo II motor for my '85 4000, they
told me how to bypass the rev limiter; I'll see if I still have the note
with their instructions around somewhere.  They also recommended the 16v
computer from a late-model VW Scirocco since it comes with a 7200rpm rev
limiter and runs a bit richer through the mid-range.  If you're careful,
it's possible to swap the circuit boards from one of these into the Audi
ECU box so no one's the wiser ... not that I would do this, of course!
