Fault table for the Gateway
   
Fault table for the Gateway
  Note
t  All the possible faults which can be detected by the vehicle system tester -V.A.G 1552- are listed below according to the 5-digit fault code.
t  After repair always interrogate the fault memory using vehicle system tester -V.A.G 1552- and erase the memory.
t  All static and sporadic faults are stored in the fault memory. A fault is detected as static if it exists for at least 2 seconds. If the fault is then no longer present, it is stored as a sporadic (temporary) fault. “/SP” appears on the right of the display.
t  After switching on the ignition, all the faults which exist are set to sporadic and are not stored as static faults unless they continue to exist after completing the check.
t  If a sporadic fault no longer occurs during 50 driving cycles (ignition on for at least 5 minutes, road speed > 30 km/h), it is erased.
