Fuel Injector: Testing and Inspection
WARNING
The check involves partial dismantling of the car's fuel system. The following points should therefore be observed in connection with the work:
-
Work only in a well-ventilated area! If approved equipment for the extraction of fuel vapor is available then make sure it is used.
-
Wear suitable gloves! Prolonged contact with fuel can cause skin irritation.
-
Keep a class BE fire extinguisher close by! Be mindful of the danger of sparks caused by short circuits and when connecting and
disconnecting leads in electrical circuits.
-
Smoking is strictly forbidden.
IMPORTANT Great cleanliness must be observed when working on the fuel rail and injectors. Wash valves, fuel rail and intake manifold and clean
them with compressed air.
1. Remove the fuel rail.
2. Fit the fuel connections to the fuel rail.
Fit a transparent hose on the nozzle. This hose should be about 40 cm long and have an inside diameter of 15 mm.
3. Direct the hose into a receptacle/measuring glass.
4. Plug in the connectors to their respective injectors.
5. Start the fuel pump by connecting cable no. 83 93 886 between fuel pump fuse no. 32 bottom pin, and luggage compartment lighting fuse no.4, top
pin.
6. Carry out the flow capacity check using the diagnostic tool. This tool will activate the injector by supplying it with battery voltage for exactly 30
seconds.
