Decoding an ESP Bosch part number

Hi everyone,
I haven't worked on that topic for several years. There used to be an online Bosch database where you could enter a Bosch part number and get all sorts of information about it. However, I can't find it anymore.

Specifically:
Fuel injection pump 0460 130 108G.
Installed on an Audi 2.5L TDI engine with MKG AAT.
Can you determine whether an ESP uses a potentiometer or an HDK based on its model number?
The pump connector is round with 8 pins and square with 3 pins, which is not unusual.
Audi still used ESP (Electronic Stability Program) with potentiometers in the early 1990s, which is why I'm asking this question.

Here's what the ESP looks like.
