I woud definitley replace the 40 a Orange with a working one. Maybe the breakpedal switch underneath the brake. 6 euro pièce.

Hydaulic unit check f72 & 73 @ front prefuse box shown above. FYI 40A fuse is for secondary air pump (M33).

Also with The Car Running I tested the Brake pedal with the Scanner and it showed the pedal switch working Fine
