Irregular engine brake

Hello, everybody.

we'll get to my second problem... 🤪

I've been the proud owner of an A6 C6 (F4) BJ '06 with Tiptronic and about 172,000km on the clock for a few months.
The engine is already 349hp.

The engine brake drives me a little crazy...
And that's the super irregular.
I'll have to tap the accelerator, then it'll work... It's just super annoying!

For example, if I did. ==References== Gear roller, he has engine brake up to about 1100 rpm.
Then he switches to the 5th. back, which is also normal, is then at 1400 rpm, and has no engine brake anymore...

This phenomenon actually takes place in every course or course. Turn it back on like that. Even if I switch back myself, because I want to have motor brake, it is then sometimes at over 2000 rpm and gives me absolutely no motor brake!?!? WTF? ==References====External links== and 3. Aisle)
It shows me in 3 gears at 2000 revolutions 8 liters of instantaneous consumption without getting noticeably slower! And that's a big pointer for me! xD
Firstly, because I want to have engine brake and slow down, secondly because the car does not react as I expect it to be, and of course also because this means that the fuel consumption is unnecessarily higher!
Another example: if I roll somewhere in 4 gear, he has engine brake, goes down to 1500 rpm, then I go into 3. Gear shift, he suddenly has no MB at 1800 rpm.

Sometimes when I tap the accelerator again, the engine brake with 0 liters of instantaneous consumption works on one time. But not always!
More often the MB works when I switch back manually, and in the automatic switching process the accelerator pedal again tap.
In principle, the smaller the gear and the lower the speed, the less often the motor brake is used.
In lower gears 2. or 3. Gang then stops the engine brake even earlier. Sometimes at 1400, sometimes even at 1800 revolutions.

Was liefert hier falsche Werte? Luftmengenmesser? Drosselklappe? Bordelektronik im Allgemeinen ne Macke?
Well, that's not normal...

Thank you for your help!
greetings
