Audi A6 2.5 TDI: Starting Problems, Won't Start

Hello everyone,
My 2001 AYM is causing me concern.
After a flat tire, my "Red Devil" car is having some kind of problem.

After the explosion, my engine started to spin out of control.
Rough idle, and two instances of brief power loss during driving.

He simply walked out, right in the middle of the city.
With the help of the Startpilot software, he restarted it, and it ran normally.
20 minutes later, red light, and then suddenly, it's off.
Startpilot, go again.
Parked the car at home.
Tomorrow, I'm tired, and I don't feel like driving.
The error code indicated a problem with the needle lift actuator.
Fehler gelöscht, sprang nicht an. Also startpilot und er lief, komisch, aber lief. Error reappeared.
My colleague is currently disassembling a 2.5-liter engine with 163 horsepower.
He gave me the spark plugs, as well as all 6 ESD tires (4 weeks old, with proof of purchase).
Everything was installed, and it started briefly, but then it ran for about 5-10 minutes and just shut off.
It's been 9 days now, and he still hasn't.
In the meantime,
Hydros.
Tilting lever.
Shim under the valves.
Switched.

I was just talking to a friend of mine (a diesel enthusiast) about this topic, and he said that since I drive an AYM and he has a BGH (I think that's what it is), the ESF and NHG would need to be programmed via VCDS.
Could that be related to the pairing process?

The VP44 works fine when it's running.

Don't give up hope.

Hi.

The first area of concern for V6 TDI engines of this type is the VP44 injection pump and its control unit.

I had already considered the issue with the VP44.
A mechanic/car expert took a look at the car.
He suspected LMM.
I removed the mass airflow sensor (MAF) from the butcher's shop's car and installed it in my own.
It only started with the Startpilot, and with this MAP sensor, I couldn't even accelerate. My old one works perfectly fine.

I have an OBD II scanner.
Cartrend On-Board Diagnostics (OBD) II.
It didn't show me any errors just now.
Even so, I proactively deleted the errors.
It strangely started up sometimes as well.
Viewed live data directly.
I was also able to observe the start of injection for the VP44 pump.
It was almost constantly 2 degrees below zero.
Suddenly, without any warning.
18 degrees after TDC (Top Dead Center), and it shut off.

The operator of this forum finances it, among other things, through the sale of VCDS.

Therefore, support is only provided if a legitimate version of VCDS is being used, and this has been verified through Autoscan and the serial number.

Once you meet this requirement, I'm happy to continue. However, until then, we'll have to stop here.

PS: Besides, you can already see for yourself that the tool you're using doesn't display everything correctly. If there were no errors, clearing the error memory wouldn't have made any difference. Therefore, the (admittedly high) investment in VCDS could be very worthwhile for you to get an accurate diagnosis.
