Technical Service Bulletin
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.
Tip: Comparing Measured Value Block 103 with 106 is not an accurate method for diagnosing G410. 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 that the customer did not run out of fuel at the time that the DTCs were stored. If the vehicle did have
a low fuel level, DTCs P310B00, P129E00, and/or P008A00 may be accompanied by DTC P125000. If DTC
P125000 is present, it is likely that the faults occurred due to a low fuel level and are not related to a
malfunction of the G410.
2.
Follow GFF for each DTC.
3.
To check the G410, measure the fuel pressure with a mechanical gauge (VAG 1318), using the following
method:
a.
Start the engine and allow it to idle for at least one minute.
b.
Stop the engine, but keep the ignition on.
c.
Measure the actual low-side fuel
pressure on the low pressure supply line
in the engine compartment (Figure 1).

4.
To calculate the adjusted gauge measurement value, add 1 bar to the value obtained from the mechanical
gauge.
5.
Compare the adjusted gauge measurement value to the Actual Value stored in MVB 103 field 1.
6.
If the MVB 103 field 1 value deviates more than ±1.0 bar from the adjusted gauge measurement value, then
the DTC was likely triggered by a faulty G410 low-side fuel pressure sensor. Document the adjusted gauge
measurement value and MVB value on the Repair Order, then perform the Sensor replacement procedure
below.
Sensor replacement procedure
1. Replace the G410 low-side fuel pressure sensor (Figure 2).
Figure 2. Pressure
sensor
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.
