Ist bekannt woher der schleichende Leistungsverlust kommt?

The link to the thread is above in the post.

In short, the most important thing is:

The situation is different when it comes to the performance degradation mentioned by Jochen, especially in permanent magnet (PM) motors over time during operation on the motor-PST.
Da muss man sich allerdings klar werden, welche Einflussfaktoren die Volllast, vor allem Pmax negativ beeinflussen können (wenn keine Defekte vorliegen - denn normalerweise müsste die Leistungsfähigkeit des Antriebes über die Laufzeit steigen - Reibleistungsreduktion in Motor+Triebstrang!). Bei unserem aufgeladenen, elektr. geregelten DI Motoren, sind das nicht allzuviele - genau genommen nur eines. Die Einspritzrate, also die Mengeneinbringung über die Zeit. This cannot yet be detected or corrected by the electronics.
...and since PD injectors, especially the EU4 models with their small hole diameters, apparently tend to experience slight carbon buildup over time, a decrease in performance is not surprising.
VP Fahrer sind da mE weniger betroffen.

Which vehicle would you recommend to me? I particularly value low weight and low fuel consumption, combined with maximum driving pleasure (possibly with the option for subtle tuning).

Not easy.
Both engines are fundamentally the same, with a few minor differences in the turbocharger, water pump, intercooler, and cylinder head bolts.
In terms of fuel consumption, they should be similar to drive, but it depends on the driving style and conditions.
When buying a used Audi, it's important to carefully check the previous owner, as these cars are often compared to GTIs and driven in a similar style. (Of course, there are always exceptions!)
The ASZ (Automatic Speed ​​Control) can be brought to the same level as the ARL (Adaptive Ride Level) via a chip, which might be advantageous when comparing purchase prices.

Best regards, Jochen.
