Fault table, fault codes 00515...01262
Notes:
-
◆ Explanation of the fault types (e.g. "open circuit/short circuit to earth"):
=> Fault reader operating instructions
-
◆ If components are indicated as faulty:
First check the wiring and connectors to these components as well as the system earth connections according to current flow diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).
V.A.G 1551 print out, e.g.:
16497 P0113 035
Intake air temperature sender -G42
Signal too large
Sporadic fault
Explanation:
-
◆ 16497 = Fault code
-
◆ P0113 = Additional fault code (only for USA at present and disregard)
-
◆ 035 = Fault type as a number
-
◆ Intake air temperature sender -G42 = Faulty current path or incorrect location
-
◆ Signal too large = Fault type as text
-
◆ Sporadic faults = Faults that are not always present e.g. loose contact

|
|
|
|
Signal too large
|
- Voltage supply above 16 V (alternator defective)
- Excessive voltage through starting aid
|
- Engine control unit rendered inoperative
|
- Check alternator
|
|
|
Signal too small
|
- Voltage supply less than 10 V
- Poor earth connection to engine control unit
|
- Idling speed not in specified range
|
- Check engine control unit voltage supply
Check charge state of battery
|
|
|
|
- Battery discharged
- Current draw when ignition is off
|
|
- Procedure after voltage supply has been interrupted
=> Page 24-104
|
|

|
Note to fault code 00532:
-
◆ If the fault is indicated as a sporadic fault, ignore the fault information! This fault can be stored when the engine is running for a long time at idling with lots of electrical consumers switched on and the battery is heavily discharged.
-
◆ The fault type "Signal too small" will be stored 60 seconds after starting if the voltage supply drops below 10.08 V for longer than 2 seconds (the control unit will not function below 6.0 V).
-
◆ Voltage supply is not checked when starting engine.

- Fault in the voltage supply for J17
- J17 defective
|
- With open circuit: Engine does not run
- For short to earth: Engine runs normally; however with ignition on there is a higher current draw, as the relay is permanently pulled on and the fuel pump runs continuously, even when engine is not running
