Typical.  Ingolstadt takes beer in payment, though.  Well, some of the
engineers do ...

Yup.  Zener/resistor network.  Seen it on every ECU they do, regardless
of whether it's necessary or even useful on that ECU.  Just had a MAC12D
with that done to it, although there was ample range in the sensor for
simple re-programming.  A crude bunch of bodgers.

If it's an Audi agent buying Audi parts, I have no sympathy.  The
wastegate issue is that the components of wastegates are not available
separately - if you want a stock spring, you have to buy a stock
wastegate.  Period.

All Superchips did to Charles Adair's car was wreck the ECU.  They
didn't even correct the checksum, so all of the diagnostic and test
functions were useless.

Have you pulled the codes?  Not all events (e.g., excessive knock)
light up the warning light.
