Reduced power: 130 hp TDI at top speed

Hello,
I recently bought a 2001 Passat TDI with an automatic transmission. I'm relatively happy with the performance at low speeds, but I'm not used to driving an automatic either.
However, I'm concerned about the top speed of 190-195 km/h; it can't be all there is to it! It's already registered with a value of 203 km/h. The mass airflow sensor has already been replaced, and no error codes are being displayed.
Has anyone had a similar issue before, or perhaps even encountered this exact error?
Best regards,
Volker

Mileage: 85,000 km

Please search the technical article for information on systematic error analysis.

Why was the mass airflow sensor replaced if it was working properly ("no errors")?

What do the typical parameters like air mass, Russian characteristic curve, etc., indicate?

Without more specific information, we will not be able to help you.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

A defect in the mass airflow sensor is not displayed when reading the error memory, so my Volkswagen dealer gave me a new one to try out.
Here, I expressed myself poorly; of course, I returned this item after no changes occurred.
The air mass and control of the turbocharger were also checked and measured today, and they show no abnormal readings!
Unfortunately, my VW dealer seems to have run out of ideas as well.
