Interrogating and erasing fault memory
Fault table
Notes:
-
◆ If faults occur in the sensors and components being monitored, they will be stored in the fault memory together with an indication of the type of fault.
-
◆ Faults relating to the electronic throttle are also indicated by the EPC warning lamp in the dash panel insert (EPC = Electronic Power Control).
-
◆ Sporadically occurring faults (temporary faults) will be indicated on the V.A.G 1551 display as "SP". The word "sporadic" means "intermittent" or "occurring at irregular intervals".
-
◆ The fault table is arranged according to the 5-digit fault codes in the left-hand column.
-
◆ If a fault is stored in the fault memory and then does not occur again during the next 40 engine warm-up phases, the fault code will be automatically erased.
-
◆ Components that are indicated as being faulty by the V.A.G 1551 should not be renewed immediately.
- Always start by checking the wiring and connectors for the component using the current flow diagram.
- Also test the earth connections using the current flow diagram. This is particularly important in the case of sporadic
faults (indicated by the letters "SP"on the fault reader display).
-
◆ If the connector for the engine control unit is unplugged or if the battery is disconnected, all the learned values stored in the control unit will be erased, although the contents of the fault memory will remain intact. The next time the engine is started the idling may be rough at first, in which case it should be left to idle for a few minutes until the learning process has been completed.

Fuel status too low
|
- Successive fault =>Note
|
Note:
The fault "Fuel status too low" is stored in conjunction with misfiring or faults relating to lambda control, if the fuel level in the tank is or was too low. The fault is stored in the fault memory as a static fault and is not set to a sporadic fault even if, for instance, the tank was filled in the meantime.
1) If this fault occurs the engine control unit activates the EPC warning lamp in the dash panel insert.
