Supersedes Technical Service Bulletin Group 24 number 07-08 dated June 19, 2007 to update parts numbers.
Vehicle Information
Condition
MIL on due to DTC P310B and/or P129F present in data memory.
Technical Background
Due to fuel intrusion into the low pressure side fuel pressure sensor (G410), a false signal may be sent to the controller resulting in a reading that is out
of tolerance. The false signal results in the setting of DTC P310B or DTC P129F and illumination of the malfunction indicator lamp.
Production Solution
G410 fuel pressure sensor improved to be more resistant to fuel intrusion.
Service
For all FSI vehicles except the 3.2L FSI:
1.
Check to ensure:
^
DTC P310B and/or P129F is present in data memory.
^
No other fuel delivery system DTCs that clearly indicate a component failure (DTCs for fuel delivery system component electrical faults) are
present.
2.
Start engine and allow it to idle.
3.
Disconnect the fuel metering valve connector (N276 or N290) on the high pressure fuel pump.
4.
Compare fuel pressure values from MVB 103 field 1 and MVB 106 field 1.
For vehicles with 3.2L FSI engines:
1.
Check to ensure:
^
DTC P310B and/or P129F is present in data memory.
^
No other fuel delivery system DTCs that clearly indicate a component failure (DTCs for fuel delivery system component electrical faults) are
present.
If both conditions are met, continue with this procedure.
