Customer states:
 MIL on.
 The vehicle either runs roughly or does not start.
Workshop findings:
One or more of the following DTCs is stored in the engine control module (ECM), J623 (address word 0001):
 DTC P008700 (Fuel rail/system pressure - too low).
 DTC P008800 (Fuel rail/system pressure - too high).
 DTC P019100 (Fuel rail pressure sensor “A” circuit range/performance).
Technical Background
Metallic particles in the high-pressure fuel pump may cause the condition.

Production Solution
Not applicable.
Service
Note:
Before proceeding, perform all GFF diagnostic procedures and check all components to determine a root cause of
the condition, including testing supply pressure to the high-pressure fuel pump (a low-pressure side) and checking
for internal leakage from the injectors and N276 pressure regulating valve.
If there is no root cause found, use the following procedure to check for metallic particles in the high-pressure fuel
pump.
Initial diagnosis of high-pressure fuel pump:
1. Prepare to remove the N290 fuel metering valve by
first cleaning the area around the valve then drying the
area using compressed air (Figure 1). All debris must
be removed from the area to ensure that no debris
enters the fuel system and causes damage.
More information is available in the Elsa at Repair
Manual, Engine >> Fuel Supply System >> General
Repair Information >> Clean Working Conditions.

metering valve.

2. Remove the N290 fuel metering valve, and inspect
both the valve and valve bore for metallic particles
(Figure 2).
Figure 2. N290 fuel metering valve and valve bore
shown with and without metallic particles.
3. If metallic particles are found:
 This bulletin applies.
 The high-pressure fuel pump and major
components of the fuel system will need to be
replaced. Proceed to the next section for
instructions.
If metallic particles are not found:
 This bulletin does not apply.
 Reinstall the N290 fuel metering valve using light
pressure. Before reinstalling, ensure that the valve
is free of contaminants.
 Install and hand-tighten both M5 fasteners,
ensuring that the threads are clean and dry (pretighten to 2 Nm, then to 6.5 - 7 Nm).
Figure 3. N290 fuel metering valve O-rings.
Note:
Before reinstalling the N290 fuel metering valve, check
the O-rings for damage (Figure 3). If any damage is
found, the high fuel pressure pump must be replaced
outside of this bulletin.
To prevent damage to the O-rings during reinstallation
of the valve, lubricate the O-rings with diesel fuel.

High-pressure fuel pump replacement and fuel system repair:
Before proceeding, check ElsaPro for the latest information and detailed instructions for the removal and
replacement of the components listed in this TSB.
1.
Use suction pump VAS5226 to clean the fuel delivery unit and fuel tank.
2.
Fill the fuel tank with five liters of fresh diesel fuel.
3.
Use suction pump VAS5226 to completely drain the fuel tank.
4.
Replace the in-tank fuel pump.
5.
Replace the suction jet pump.
6.
Following the instructions in the Elsa repair manual, replace the following components:
 High-pressure fuel pump (note that the supply and return line orientation for the HPFP may be reversed
on updated pumps installed on vehicles manufactured before 05/25/2010).
 High-pressure fuel lines.
 Fuel rail (with both sensors included).
 All fuel injectors.
 Fuel return lines (overflow oil lines).
 Fuel filter.
 Fuel filter housing.
 Auxiliary fuel pump.
7.
After replacements are complete, then fuel the vehicle.
8.
Ensure that the fuel injector return line is properly seated and sealed.
9.
Using the VAS tester, perform the “Vent Fuel System” Guided Function. See Elsa at Repair Manual, Engine
>> Fuel Supply System >> 20 Fuel Supply >> Fuel System, Bleeding for additional information.
Tip: If the test plan is unavailable through Guided Functions, switch to Self Diagnosis >> Engine
Electronics >> Basic Settings >> 35, and perform the basic settings three times consecutively. For UDS
vehicles, perform basic settings for initial fueling.
10. Once the repairs are complete, then test drive the vehicle.
11. Inspect for fuel seepage at the fuel injector return line connector. If seepage is found, the condition must be
corrected.
