hello
A well-known person mentioned that you can identify whether a car has an EMS (Electronic Manual System) or a ZMS (Zero-Point Manual System) by looking at the gearbox. If it has an EMS, the sensor is mounted on the gearbox and there's a fork that goes into the gearbox. If it has a ZMS, the sensor is directly inside the gearbox.
Okay, here's the translation:
"Now, there's a real difference. On the February 1997 TDI model, I have the sensor on the transmission and a lever. On the later model (late 1997), I only have a hose going into the transmission, and definitely a dual-mass flywheel."
After I planned to use the parts from the "Schlachter" (a source for used parts) for the upcoming clutch replacement, I need to know if it's actually possible that my TDI has an EMS (Engine Management System).
"Thank you."

To the best of my knowledge, all 5-cylinder TDI engines, starting from 1994 or with the renaming of the Audi 100 to the A6, have a dual-mass flywheel. Gruß Christian

"Thank you!"
I heard from "the rolling community" that the Volvo only used the ZMS (dual-mass flywheel).
"However, since there are more people working on gasoline engines there, and with gasoline engines, the change from an EMS (Electronic Motor System) to a ZMS (Mechanical System) is related to the sensor cylinder on the transmission, or then with a ZMS central release mechanism, I was a bit confused."
In the TDI engine, the older fork and central release bearing configuration should have a dual-mass flywheel (DMF).
Sure, here is the translation of the text from German to English:
