Technical Service Bulletin
Technical Background
A false signal may be sent to the controller due to fuel intrusion into the low-pressure system fuel pressure sensor,
G410. The result is a reading that is out of tolerance.
G410 must be accurately diagnosed with a mechanical gauge, and the results must be compared with the low-side
fuel pressure actual value in Measured Value Block (MVB) 103. Comparing MVB 103 with MVB 106 does not
accurately diagnose G410.
Production Solution
Improvements to G410 fuel pressure sensor.
Service
1. Verify that 24T4 UPDATE - Fuel Pressure Sender (Warr_Ext) was performed (if applicable).
2. Verify the customer did not run out of fuel at the time the DTCs were stored.
3. Follow indication 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:
a. Start engine and allow it to idle for at least one minute.
b. Stop the engine.
c. Keep the ignition on.
d. Measure actual low-side fuel pressure via
mechanical gauge (VAG 1318) on the low
pressure supply line in the engine compartment
(Figure 1).

5. Add 1 bar 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.
7. 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. 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 low-pressure system fuel pressure sensor, G410
(Figure 2).
Figure 2. G410 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.
