My Smart Fortwo 451 Diesel built in 2009 has the following problem, error code P2359 pressure regulator charge. There is no more turbo and goes constantly into the emergency run. The workshop meant that the pressure converter is responsible for the turbo. I bought and let me change the valve, but the error has not been fixed. Does anyone have any idea what that can be? I am very grateful if someone has any idea, thank you.
