Alfa Giulietta - A/C pressure makes no sense for MM ECU

Hi,
Today I examined my friend's Giulietta 1.4MA 2010 (Magneti Mareli ECU), and compared with my Gulietta 1.4TB (Bosch ECU).
What odd I noticed was that A/C pressure on MM ECU was nearly stuck, just 2 values ever either 0.05bar or 0.048bar (A/C at LO setting, and producing correct freezing air~4 C deg (mean just that it was working fine), while on Bosch ECU I got proper Graph ramping betwen 12 - 15bar (with similar ~4C deg produced air temperature).
Could you please check and correct.
Thx
