| Remove fuses -4- and -43-(for the electric fuel pump control unit) in the fuse holder, below the instrument panel, left-hand side, and continue reading display field 3. The engine continues to run at idling speed. |
The value shown in display field 3 drops rapidly as the mechanical high pressure pump is no longer fed by the electric fuel pump from the tank. |
Note The display should not read below 6 bar; if so, the engine will stall (with the ensuing risk that the catalytic converter is damaged). |
–
| Switch off the ignition when the value displayed is approx. 8 bar. |
The fuel rail is still full, however, the fuel is no longer under high pressure. |
The components or pipes may now be disconnected. Put a clean cloth around the joints. Catch the fuel coming out. |
–
| Reinsert fuses 4 and 43 (for the fuel pump control unit). |
