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.
Comparing Measure Value Block 103 with 106 is not an accurate method to diagnose low-side fuel pressure
sensor 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 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 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).
Figure 1. VAG 1318 gauge installed on an A3 2.0L TFSI.
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 G410 low-side fuel pressure
sensor.
Figure 2. Pressure sensor 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.

Service
1. If you are performing this TSB because of a reference in TSB 2016868 or 2015505 proceed as follows:
• Inspect if the 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.
• If you are not performing this TSB because of a reference from TSB 2016868 or 2015505; proceed to Step 2.
2. Verify the customer did not run out of fuel at the time the DTCs were stored.
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 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.
