Performing actuator diagnosis
With the actuator diagnosis the following parts are activated in the sequence indicated:
   
1.Fuel pump relay -J17-
2.Solenoid valve 1 for activated charcoal filter -N80-
3.Secondary air inlet valve -N112- → Note
4.Secondary air pump relay -J299- → Note

1)  Disregard display
  Note
t  The actuator diagnosis can only be carried out when the engine is not running and the ignition is switched on.
t  The final control diagnosis is aborted when the engine is started or when a moment of momentum is detected.
t  The actuators are tested acoustically or by touch.
t  If final control diagnosis is to be repeated wirthout starting the engine in-between, switch ignition off for about 20 seconds.
Test conditions
l  Fuses must be OK in compliance with the current flow diagram.
Special tools and workshop equipment required
t  Vehicle system tester -V.A.G 1552-
t  Diagnostic cable -V.A.G 1551/3, 3A, 3B oder 3C-
Procedure
–  Connect vehicle system tester -V.A.G 1552-. Switch ignition on and select address word 01 “Engine electronics”.
–  Enter function 03 “Final control diagnosis”.
   
The fuel pump relay (on the relay plate, relay position 15) must click until the next actuator is activated by pressing →.
