Error code on 1.9 TDI AFN engine - Strange error!

Hello to all you tech freaks .

I'm having a small problem with my...
A4 B5 1.9 TDI AFN 110 hp.
-no chip, if suspected-

Now I'm having problems with something that's happening under...
The performance seems to be dropping off slightly.
'Hey, I'm driving on the highway at 160 km/h.'
and I have to brake - the acceleration.
It takes forever afterward... also, it speeds up.
The performance drops when going uphill.

Not too long ago, I had already...
'Lack of power, but the mass airflow sensor (MAF) was replaced there.'
And then everything was working again.

Now I've borrowed an OBD2 interface, and with...
retrieve the engine fault memory in an English VAG-COM 3 demo.
selected, and the following can be found there:

VAG-COM Version: Release 311.2-N.

Control Module Part Number: 028 906 021 CE

Can anyone possibly help me with this?
I am grateful for any advice.

Wishing everyone a lovely evening!

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

'lg' translates to 'best regards' or 'kindly regards' in English. It is a common abbreviation used at the end of emails and letters.
