Boost pressure limit error code: 17965 - Test drive log

Hello everyone,

auf meiner letzten längeren Fahrt, 700 km BAB, ging mein Golf IV (AXR, alles original) zweimal ins Notlaufprogramm. Jeweils nach einem neuen Motorstart war alles wieder normal. Beim zweiten mal fand die Notprogrammschaltung während des Beschleunigens im 5. G'ang' is used instead of 'and'.

The diagnostic scan after the trip revealed:
Error code: 17965
Boost pressure limit occasionally exceeded.

An initial visual inspection revealed no major hose damage in the vacuum system. Furthermore, nothing has been assembled or installed on it yet.

So, I conducted a test run today. The emergency program activation could not be reproduced.

The VTG basic settings were also performed.
Rotation speed during test (automatic): 1407 RPM.
Maximum boost pressure: 1122 mbar.
Boost pressure min.: 989 millibar.

As far as I've learned from this forum, the turbochargers are likely filled with a generous amount of air for exhaust gas optimization, and it seems that overshooting the boost pressure is normal.

Here are my questions:
1. Does any of the experts see anything unusual in the log? Could it be that the car just had a bad day, and I can still hope for spontaneous self-repair? Perhaps it was a bit too much uphill driving, which it's not used to, and it was also quite warm?

What is the maximum permissible deviation?

Thank you for your help.

Regards,
