Condition
01 12 20 June 29, 2012 2027458 Supersedes T. B. V011207 dated March 19, 2012 to update warranty claiming
service number information.
MIL ON DTCs P310B, P129F, P008B, P129E, P008A, P2540 or P0087 Stored in ECM Fault Memory
MIL ON and one or more of the following DTCs are stored in the ECM data memory:

DTC

Description

P310B

Low-pressure fuel system regulation, fuel pressure
outside tolerance

P129F or P008B

Low-pressure fuel system, pressure too high

P129E or P008A

Low pressure fuel system, pressure too low

P2540

Low pressure fuel system, pressure out of range

P0087

Rail fuel pressure system, pressure too low

Technical Background
Due to fuel intrusion into the low-pressure system fuel pressure sensor (G410), a false signal may be sent to the
controller, resulting in a reading that is out of tolerance.
Comparing Measure Value Block 103 with 106 is not an accurate method to diagnose low-side fuel pressure
sensor G410.

Technical Bulletin
In order to diagnose G410 accurately, use a mechanical gauge and compare results with the low-side fuel
pressure Actual Value in Measured Value Block 103.

Production Solution
Improvements to G410 fuel pressure sensor.

Service
1. Verify the customer did not run out of fuel at the time the DTCs were stored.
2. Inspect that latest fuel pressure sender P/N 06E 906 051 K (Figure 2) is installed, if not replace the old style
component with the new style component and run Basic Settings 103 to adapt system.

Tip:
P310B and/or P129E/P008A may be accompanied by P1250. If so, it is likely the faults occurred due to a low fuel
level and not a malfunction of the -G410- Pressure Sensor.
3. Follow diagnostic program of GFF for applicable DTCs.
4. To check the low-side fuel pressure sensor -G410-, measure the fuel pressure with a mechanical gauge using
the following method:

4a. Start engine and allow it to idle for at
least one minute.
4b. Stop the engine.
4c. Keep the ignition switch ON.
4d. Measure actual low-side fuel pressure
via mechanical gauge (VAG 1318) on the
low pressure supply line in the engine
compartment (Figure 1).

Figure 1. VAG 1318 gauge installed on a 2.0L
TFSI.

5. Add 1 bar (14.5 psi.) to the value obtained from the mechanical gauge to calculate the adjusted gauge
measurement value.
6. Compare the adjusted gauge measurement value to the Actual Value stored in MVB 103 field 1.

Technical Bulletin
7. If the MVB 103 field 1 value deviates more than ±1.0 bar (±14.5 psi.) from the adjusted gauge measurement
value, then the DTC was likely triggered by a faulty -G410- low-side fuel pressure sensor. In this case, document
the adjusted gauge measurement value and MVB value on the Repair Order and perform the Sensor replacement
procedure below.
Sensor Replacement Procedure

1. Replace the -G410- low-side fuel pressure
sensor with P/N 06E 906 051 K.
2. Clear DTCs and verify that the problem was
eliminated.
3. Run Basic Settings 103 to adapt system.
4. DO NOT replace the high pressure fuel
pump, electrical fuel pump, fuel pump control
module or fuel filter unless problem persists
and further diagnosis indicates a malfunction
of any of these components.
