Technical P0237 Turbocompressor turbopressure sensor A signal too low, problem

[KaptajnNHH]

Hello everyone!

2009 Fiat500 1,3 Multijet 75hp
101.000 km

I have this check engine light which is getting triggered on highway speeds above 120 km/h for a short time, (i can drive for weeks without error as long as its below that)
I have attatched the freezeframe data from last time i triggered the check engine warning:
The car will loose some performance with the check engine, but not go into limp mode like on other cars as i can still accelerate to 120+ km/h

So far i have changed the MAP sensor which did not help so far!

Where should i look next? Is there any sensors on the turbocharger etc.?
Or could it be that the Turbo is just too worn to perform at high speed?


Thanks in advance guys hope to get your input!
