TDI 1.9 Engine Failure: E-Pump Replacement

Hello friends, I need a tip for troubleshooting from you.
I replaced the timing belt and fuel injection pump on my 110 hp TDI, manufactured in December 1999.
After adjusting the pump using a measuring device, the motor "stalled" slightly.
but performed well.
Then I checked and adjusted it using VCDS and the TDI Graph software.
I was set to a value above 90, but it wasn't even displayed.
After adjustment to 55 (see image), "improved engine performance."
however, with less power and during acceleration.
The engine keeps stalling; you really have to...
press the gas pedal and let the clutch slip.
can be approached. ???
It's really bad when it's cold, and even when it's warm, it's not great.
Would anyone have a tip for troubleshooting ?

I definitely have this fuel injection pump installed: 0460404986 - it should fit.

Sure, here is the translation of the text from German to English:

"Lg" is a German abbreviation that stands for "Liebe Grüße," which means "Best regards" or "Warm greetings" in English. It is commonly used in emails and other written communications to express a friendly and informal tone.

Hi,

You have selected the wrong engine setting using VCDS, as shown in the Screenshot in the bottom right corner.

The engine code should be ASV for you. Therefore, it makes sense to post an Autoscan here, especially if it says "post an Autoscan" somewhere.

Regardless of whether the settings are correct or incorrect, I suspect that the engine has already been run for a long time based on the year it was manufactured.
For this type of fuel injection pump, except for long-distance vehicles, it's common that after 250,000 km, the injection timing adjustment may no longer function correctly. An early injection start can then be difficult or impossible to adjust, causing the engine to gradually fail under heavy load and high RPMs.

There are many posts on this topic available here; please refer to the search function for more information. Also, see the technical articles on adjusting the fuel injection pump.
