Connect vehicle diagnostic tester and then carry out the
function “Reducing high fuel pressure” in “Guided functions”. |
| The fuel pressure will drop to the specified value. |
| The fuel rail is still filled with fuel, but the fuel is not
under high pressure anymore. |

After the high pressure has been released, the high-pressure
system must be opened »immediately«.
To do this, wrap a clean cloth around the connection before
opening it. Catch the escaping fuel. |

pressure will rise again due to reheating effects. |

switching the ignition on would cause the pressure to rise
again. |
