Service
Prior to replacing a fuel injector, check the wiring pin connectors as described in the following work procedure:
- Locate affected cylinder.
- Swap ignition coil, spark plug or fuel injector from affected cylinder to another cylinder and observe if problem moves with the swapped component.
If problem moves with swapped component:
- Replace that faulty component.
If problem remains at the same cylinder:
- Check electrical connectors of fuel injectors as follows:
- Disconnect connector of fuel injector(s).
- Remove contact pins from the plug housing:
- Push plug out of housing by releasing locking tabs -A-.
- Remove secondary lock -B- upwards.
NOTE:
Use appropriate tool from the VAS 1978 Wiring Repair Kit.
- Push tool into slot -C- and remove female terminals from connector.
With terminals removed from connector:
- Push terminals (trial fit without housing) successively onto the appropriate male terminals of the injector.
- Female terminals should fit snugly.
If the female terminals slide without resistance onto the appropriate injector:
- Replace affected female terminals using the VAS 1978 wiring repair kit. See ETKA Special Catalogues for wires for connector housing 06A973722.
Tip:
When repairing wiring, always follow instructions included in the VAS 1978 Wiring Repair Kit.
If the contact pins fit snugly to the pins:
The affected component needs to be checked using the VAS 5051 or VAS 5052 diagnostic tool and Guided fault finding.
