Alfa Giulietta cannot calibrate Xenon Headlights

[Ruggero1912]

Good morning everyone.
I have an Alfa Giulietta 2.0 with original Xenon Headlights pack.

I noticed that the beam lights are facing too downwards.

For this reason I tried to calibrate the Xenon unit from MES, but it returns me an error, even though I placed the Giulietta in the required conditions (flat surface, no one in the car, low beams turned on).

In the following image I reported a screenshot showing the values read from MES.

I have the doubt that the pitch is not correct, but I am not sure about that, what is considered a correct value when the car is on flat ground?

Do you know what component could cause wrong measurements of this value?

Thanks for your attention

check sensors physically if they are OK. voltages don't look correct.
