I've had nightmares with these dashes , check the buttons on the dash as they give lot of trouble and can interfere with display !p32 is a common display fault code on these also. Did you remove mcu or what did you use to read it ??

I read it on board with UPA I have to lift pins 17,20,21 and 26 the mask is 4E28B (HC11E9), I will check the buttons ... thanks
