GTI V6-2.8L (BDF) (2002)
-
Check resistance of fuel injectors between terminals.
Specification: 13.0 to 19.0 ohms
NOTE The resistance value is valid when measured at approx. 20 degrees C. The resistance value increases at higher temperatures.
If the specification is not obtained:
-
Replace faulty fuel injector, item 7. Refer to "Fuel Delivery and Air Induction/Fuel Rail",
See: Fuel Rail/Service and Repair
Observe the following when installing fuel injectors:
-
Replace O-rings on all fuel injectors and moisten then lightly with clean engine oil.
-
Insert fuel injectors vertically and in the correct position into the fuel rail and secure with retaining clips.
-
Set fuel rail with secured fuel injectors on cylinder head and press in evenly.
-
The connectors must audibly engage in the fuel injectors when pushed on.
-
Check DTC memory, repair malfunctions if necessary and then erase DTC memory.
See: Computers and Control Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes
-
Erase learned values and adapt Motronic Engine Control Module (ECM) -J220- again.
-
Read readiness code. If the DTC memory has been erased or the Motronic Engine Control Module (ECM) -J220- was disconnected from battery
positive (B+), the readiness code must be generated again.

Checking voltage supply
-
Connect VAG 1527 LED test light to terminal 1 and ground (GND) of relevant fuel injector connector using adapter cables from VAG 1594.
-
Operate the starter and check the voltage supply for the fuel injector. The LED must light up
-
Switch off ignition.
If the LED does not light up:
-
Check wire for open circuit between 2-pin connector terminal 1 and Fuel Pump (FP) Relay -J17- referring to Electrical Wiring Diagrams.
Wire resistance: max. 1.5 ohms
Checking activation and voltage supply
-
Connect VAG 1527 LED test light to connector terminals of fuel injector to be tested using cables from VAG 1594.
-
Operate starter and check the activation for the fuel injector.
The LED must flicker
-
Switch off ignition.
The LED does not flicker:
-
Remove wiper arms and cowl panel:
