I changed the fuel rail pressure regulating valve on my M57 engine and now it dosen't start. I tried to find in ista an option to reset adaptations but i didn't found any. I also tried the ignition on/off procedure (to bleed the system)

The car was running with the old valve. After I installed the new valve and saw that it wasn't working, I tried putting the old one back in, but it still won't start.
