–
| Repeat pressure test by setting valve -D- again to „Test“. |
–
| Observe pressure gauge and flow meter. When the throughput quantity decreases and the pressure increases to 10 in. H2O (25 mbar), the fuel system is filled. |
–
| Once pressure has stabilised, set valve -D- to „Hold“. |
–
| If the pressure does not drop again, renew activated charcoal filter solenoid valve 1 -N80-. |
If the pressure still drops, perform „leak detection in fuel system“ → Chapter. |
After completing work, perform guided function „checking fuel tank ventilation system for leaks“ using vehicle diagnostic tester. |
