| Observe fuel pressure in display zone. |
l
| The fuel pressure will decrease very quickly because the mechanical high-pressure pump is no longer being supplied with fuel by the fuel system pressurisation pump -G6-. |
–
| As soon as the fuel pressure has fallen to approx. 8 bar, turn off the ignition. |
Note Fuel pressure must not fall below 6 bar, otherwise the engine will stall (this could damage the catalytic converter). |
WARNING The fuel lines are still filled with fuel, the fuel is not under pressure any more. Wear safety goggles and protective clothing when opening the fuel system to avoid possible injury and skin contact. |
Before opening the high-pressure section, wrap a cloth around the connection. |
|
–
| The high-pressure system must be opened »immediately« after reducing the fuel pressure in the system. Place a clean cloth around the connection for this purpose. Catch the escaping fuel. |
The following operations must be performed after completing repair work: |
–
| Erase event memory and generate readiness code in engine control unit in „Guided Functions“ mode. |
