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

light up the warning light.
