New Beetle L5-2.5L (BPS) (2006)
Checking voltage supply
-
Switch the ignition ON.
-
Using a multimeter, check the Ignition Coils with Power Output Stage (N70, N127, N291, N292, N323) electrical harness connector terminal 1 to
ground for voltage.
Specified value: Battery voltage.
-
Switch the ignition OFF.
If the specified value was Not obtained:
-
Check the Ignition Coil electrical harness connector terminal 1 through fuse S130 to the Motronic Engine Control Module (ECM) Power Supply
Relay (J271 ) for an open circuit.
-
Check the wiring connection for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection and replace fuse if blown.
If the specified value was obtained:
Checking activation
CAUTION!
Do not touch the Ignition Coils connecting parts or adapter cables during the following test.
-
Disable the power supply to the Fuel Injectors ( N30, N31, N32, N33, N83) by removing Fuse S229.
-
Using a diode test lamp connected to ground, check the Ignition Coils with Power Output Stage (N70, N127, N291, N292, N323 ) electrical
harness connector terminal 3 of each coil.
-
Operate the starter.
The LED should blink.
-
Switch the ignition OFF.
If the LED blinked and the voltage was OK:
-
Replace the faulty Ignition Coils with Power Output Stage (N70, N127, N291, N292, N323) Refer to the Repair Information.
If the LED did Not blink:
Checking wiring
